Subscribers to UL?s Listing Service for: Flexible Cords and


Cables (ZJCZ, ZJCZ7) and Electrical Vehicle Cables (FFSO, FFSO7)




New Issue of the Follow-Up Inspection Instructions (FUII) for


Flexible Cords and Cables(ZJCZ, ZJCZ7) and Electrical Vehicle


Cables(FFSO, FFSO7)




UL has developed a new issue of the Follow-Up Inspection Instructions (FUII)


for Flexible Cords and Cables (ZJCZ, ZJCZ7) and Electrical Vehicle Cables


(FFSO, FFSO7). The new issue Follow-Up Inspection Instructions (FUII) updates


the inspection instructions with current practices as noted in previously


issued bulletins and incorporates the latest revisions to UL 62, 18th Edition,


the Standard for Flexible Cords and Cables. Therefore, except as noted


elsewhere in this bulletin, the FUII are considered effective upon receipt as


they do not alter the FUS program currently in effect at your facility.



The new issue of the FUII was circulated to industry in a memo dated May 13,


2011 and all comments received were incorporated where applicable.





The following summarizes the changes in the FUII:



I.



General Inspection Guidelines


a.



Removed Bulk Labeling Option from Label section.


b.



Revised label section - Flexible Cord requires the use of


Type L Holographic labels, therefore machine


imprinting/computer-Generated Labels will no longer be an


option and will be deleted. Please refer to L2.


c.



In addition to the Compound Recognition Program (QMTT2) and


Unlisted Component Program (QMTT3), the Field Representative


shall also confirm if the compound is acceptable for cords with


a ?


-


R? suffix.


Please refer to L18.


d.



A function check of test equipment is now required in


addition to calibration requirement. Please refer to L26 and


L70.



II.



Manufacturer?s Test Program and Records



a.



UL will no longer require that a UL Inspection Data Sheet be


completed during the inspection. In lieu of the UL Datasheet,


Field Representatives will confirm and witness the Manufacturer


conducting the tests specified in the FUII and verify the data


recorded on the manufacturer?s own in


-house Data Sheets/Data


Recording system per bulletin dated 4/21/2010.


b.



Added Periodic Lot testing. Please refer to L68.


c.



Other than the individual conductors of each cord, the


jacket on duplex and coaxial constructions of Elevator cables


types E, EO, ETT, and ETP also shall be subjected to the


appropriate test potential for the specific cord or cable type


indicated in the table for


Please refer to L69 b.

III.


UL Representative?s Countercheck Program



a.



Sample selection requirement was changed to more clearly


indicate the number of samples and which of those samples


should be sent to UL for FUS testing. The previous edition of


the FUII required selecting one (1) sample for every 7,500 feet


or less of


each type


of Flexible Cord available. This edition


requires selecting one (1) sample for every 7,500 feet or less


of


two types


(or one type if only one type and one temperature


rating is available for selection) of flexible cord available


when selected in accordance with L33 and Table L1 (Cord Groups).


b.



Deleted optional flame testing at factory (Vertical Flame


test



VW-1, FT-1 and Horizontal Flame test - FT2). Please


refer to L34 and Table L2. (


Effective June 1 2012.


This


option was included in the FUII but also required authorization


in the FUS Procedure. As UL revises the FUS Procedures to


include the revised FUIIs, this option will be removed from any


FUS Procedures in which it is currently included.).


c.



DC resistance of the conductor is required for all flexible


cords and cables and Electric Vehicle Cables based on revisions


to UL 62. Please refer to L34, L37 and Table L2.


d.



Detailed Examination Items shown in Table L3 were revised to


include Tearing(integral constructions only), Overall


Diameter(round service and heater cords) and Manufacturer and


grade designation of compounds used (cords using a QMTT2 or


QMTT3 compound, cords with a



R suffix, or cords with specific


compounds specified in Procedure Description only).


e.



Removed detailed measurement description for Length of Lay


from this edition. The measurement method for Length of Lay


shall follow UL 2556.


f.



Corrected testing of Coiled Cords to match UL 62. Physical


Properties Test shall be conducted on the straight portion of


the cords instead of coiled portion. Please refer to L60.


g.



Clarified tearing test requirement. Please refer to L66.




IV.



Sample Selection Instructions for Tests at UL


a.



Clarify sample selection procedure; please refer to L71-L74

a.



Added in Enhanced Mark Integrity Program (eMIP) requirements


from bulletins dated 5/1/2007, 6/8/2007 and 4/1/2008.


b.



Removed ?trend? program since significant nonconformances


are covered by Enhanced Mark Integrity Program (eMIP) and minor


nonconformances are covered by Customer Corrective Action


Process (CCAP).



VII. Others


a.



References UL 2556 rather than UL 1581 in accordance with UL


62.


b.



Corrected name of UL 62 from Flexible Cord and Fixture Wire

SCOPE



A.



These requirements cover Flexible Cord for use in accordance with Article


400 of the National Electrical Code as well as Types XTW and CXTW Decorative


Cords; Clock Cord; Heater Cord, Types HSJOW, HSJOOW and Shaver Cord. These


requirements also cover Flexible cords for use in Canada including Types DRT,


PXT, PXWT, TX and CXWT. The Standard for Flexible Cords and Cables, UL 62,


and the Standard for Wire and Cable Test Methods, UL 2556, are applicable for


inspections in this category. The Authorization Page for the Procedure will


note authorization for use of the Canadian UL Mark on Flexible Cord production


accordingly. The descriptive sections of the Procedure will identify the


Canadian Types authorized for the manufacturer, and their corresponding UL


Type Designations if products meet both Canadian and U.S. requirements, or the


Canadian Types authorized for the manufacturer for products that meet only


Canadian Requirements. The Procedure will contain instructions that cover the


generic marking, labeling and test requirements for such cords.



These instructions do not cover Hoistway Cable that is also identified in


UL 62. Follow-Up Inspection requirements for Hoistway Cable are defined in the


respective Follow-Up and Inspection Instructions and/or Follow-Up Service


Procedures for this category. For specific Flexible Cord types covered by this


FUII, refer to Table L1.



GENERAL



B. As a part of Underwriters Laboratories Inc. (UL's) follow-up inspection, it


is required that a Field Representative periodically visit the factory and


select, for test or examination or both, samples of production made since the


last inspection visit of the products covered.



C. The Follow-Up Service Procedure covering the product is loaned to the


manufacturer and constitutes the basis on which the product is judged for


compliance with the applicable requirements.




GENERAL RESPONSIBILITIES OF THE MANUFACTURER AND THE FIELD REPRESENTATIVE



The Manufacturer?s and Field Representative?s


general responsibilities, as


part of the Follow-Up Services Procedure, are as noted in the published


document title


d, “UL Mark Surveillance Requirements”, and is available through


UL?s secure customer portal MyHome@ and/or through UL?s internet site


. Manufacturers that do not have Internet access may obtain the


current version of these requirements from their local UL Customer Service


Representative or UL Field Representative.



Products in question shall be removed from service by segregation or prominent


labeling and marking.




Subject 62

Issued: 2011-08-12



GENERAL INSPECTION GUIDELINES



APPLICATION OF THE LISTING MARK TO THE PRODUCT



General



L1. If available, the Field Representative shall examine a minimum of ten


coils or reels of Flexible Cord to assure that the application of the label to


the product throughout is in compliance with the requirements of Underwriters


Laboratories Inc.



L2. Flexible Cord is covered under UL's Type L Listing Service and requires


the use of Type L holographic labels whose contents are identified in the


Section General of the Follow-Up Service Procedure. Additional information,


such as camera-ready art work and proportional dimensions for the


Marks/Markings may be found by visiting UL?s website at


“/marks_labels/”.




L3. The Listee's name, tradename, trademark or UL File Number which identifies


the Listee, must appear on a combination label, unless the subscriber chooses


to purchase standard labels from UL's Label Centers, in which case the


Listee's identification is not applicable. At least one label shall be applied


to the tag furnished with each coil or reel of Flexible Cord. The footage


represented by the label or labels shall in each case be approximately the


same as the number of feet of Flexible Cord, within ±5 percent. The Field


Representative shall verify manufacturers records or markings to confirm


footage.



L4. Each flexible cord shall have a durable distinctive marking throughout its


entire length by means of which the Listee can be identified. This shall be


accomplished by one or more of the following methods:



1.



assigned combination of colored marker threads.


2.



assigned file number, or


3.



organization name or acceptable coding such as by trade name, trademark



L5. The above identification methods are listed in order of precedence; i.e.


if the descriptive marking includes both a marker thread and a file number,


the marker thread shall be used to identify the responsible organization.




Purchasing Listing Marks



L6. Type L holographic Listing Marks for flexible cords are available in


standard format containing only UL Listing Mark information at UL?s Label


Centers, or they may be ordered as combination labels to also include the


Listee identification. Additional information on designing and ordering custom


holographic labels can be found in the Hologram UL Marks section of UL?s Marks


and labels website at “/marks_labels/”.




Surface Printing, Tag Marking and Labeling of Multi-Rated Flexible Cord




Subject 62


5


Issued: 2011-08-12


L7. Flexible Cord that is dual rated with a Recognized Component AWM style


(e.g.:


carton, and only the UL Logo in the surface print legend.




L8. The UL Logo shall consist of the letters


parentheses. For multi-rated constructions, UL requires that the UL Logo in


the surface print legend clearly associate the


types, and clearly separate the Listed cord types from the AWM designations.


Examples of proper markings are shown below:



...SPT-


2 (UL) ………………… AWM...



... (UL) SPT-2 18 AWG/2 C 300 V or AWM...



The tag marking for dual-rated cord shall account for all common and unique


requirements for each cord type identified in the cord's surface print. As an


example, for cord identified as


marking requirements for these two types would include the Listee's


identification, conductor size, number of conductors, temperature rating,


voltage rating and date of manufacture. The unique tag markings would be


applicable to the AWM category and would include such items as the insulation


thickness and the usage statement.



L9. Since the construction in the above example references one Listed cord


type and one Recognized wire type, a UL Listing Mark is applied to the tag. In


this case, a Flexible Cord Listing Mark is applied to the tag.



L10.



If the Field Representative encounters marking practices not in


accordance with the above guidelines, the situation shall be documented on a


Variation Notice. The Field Representative shall work with the manufacturer in


accordance with the “VN Handling and Processing Procedure”. Should it be


determined that the cord or cable is no longer eligible to bear the UL


Certification Mark, all cord or cable with surface printing referencing UL


shall be scrapped in accordance with L24.



Nondenominational Labels



L11.



Nondenominational labels that do not contain a denomination (length) are


available for Flexible Cords. When nondenominational labels are used, the


Field Representative shall verify that the manufacturer is maintaining


accurate records of Flexible Cord produced bearing nondenominational labels


during each calendar month. The Field Representative shall have access to


these records in order to determine and report nondenominational label usage.



L12.



The use of nondenominational labels is an option made available only to


those manufacturers whose production recording methods and controls have been


evaluated by UL, and found to be an acceptable basis for service charge


billing. The use of nondenominational labels is not required, and labels with


the footage imprinted will continue to be available. When nondenominational


labels are authorized for a manufacturer, the authorization will be indicated


in the Follow-Up Service Procedure and on the Subscriber Card (Account, Class


and Code Section). Use of nondenominational labels may be revoked if proper


controls and reporting are not maintained.




Subject 62


6


Issued: 2011-08-12


L13.



The Field Representative shall inform manufacturers interested in having


their record keeping facilities evaluated toward receiving authorization to


use nondenominational labels to contact the Label Center.



Labeling of Cut Lengths



L14.



Flexible Cord produced in-house and packaged in cut lengths by the


manufacturer is labeled differently from Flexible Cord which is received on


reels from another Flexible Cord manufacturer and then cut into lengths by the


receiving manufacturer. The procedure indicated below shall be followed when


labeling Flexible Cord which the manufacturer produces in-house and ships in


cut lengths:



a.



Place the Flexible Cord label covering the total footage of cut


lengths on the outside of the carton of cut lengths. The label shall


be so located so that the label is torn when the carton is opened.



b.



Prepare the usual engineering tag and place it inside the carton of


cut lengths. The information required on the tag can be found under


the



c.



At the location on the tag normally occupied by the Flexible Cord


label, use the statement




As an alternative to preparing the tag for cut lengths mentioned in


paragraph L14b, the manufacturer may print the required tag information onto


the carton itself. The Flexible Cord label shall then be placed on the outside


of the carton (see L14a), adjacent to the tag information, in a location where


the label will be torn when the carton is opened.



L15.



Flexible Cord that is received from another manufacturer with the


intention of being cut into lengths or respooled and labeled by the receiving


manufacturer shall already bear the UL Flexible Cord label. Manufacturers who


receive Listed Flexible Cord from another manufacturer and cut it into lengths


for resale as Listed Flexible Cord shall use Listed Processed Wire or


Processed Wire Respooled labels, as authorized by their Processed Wire Follow-


Up Service Procedure.



Surface Printing of Flexible Cord



L16.



In addition to the surface printing requirements specified in the



Logo in the surface print legend. For products meeting only U.S. Requirements,


the letters


required to appear in the surface print legend. For products meeting only


Canadian Requirements, the letters


is required to appear in the legend. For products meeting both U.S. and


Canadian Requirements, either the C(UL)US Logo or separate U.S. and Canadian


logos are required to appear in the legend. For example:



E12345 (UL) SJT 14 AWG (2.08 mm2)/2C 105C 300V VW-1 C(UL)



or



Subject 62


7


Issued: 2011-08-12



E12345 C(UL)US SJT 14 AWG(2.08 mm2)/2C 105C 300V VW-1



are acceptable markings for products meeting both US and Canadian


requirements.



Date Marking of Cord



L17.



The age of the cord is derived from the marked date of manufacture, and


is either applied to the tag, reel or carton or included in the surface


markings of the cable through the use of ink, indent, or embossed surface


print marked on the outside surface of the product as permitted in the


Standard for Flexible Cords and Cables, UL 62. The date code shall follow the


“month and year” or month, day and year” sequence (e.g. “10/02”, “Oct. 02”,


“10/31/02” or “Oct. 31, 02”, etc.). If the date code is printed on the surface


of the cord, it shall be repeated at intervals of no greater than 40 inches (1


meter). The date may be shown in code. In no case shall the marked date be


previous to the date of the 100% Production-Line testing (See Paragraph L67)


of the cable.




COMPOUNDS FOR USE IN FLEXIBLE CORD



L18.



Specific compounds shall be used as insulating materials used in


Decorative Cords and Wire, types SPT-1W, SPT-2W, CXTW and XTW as well as


jacketing compounds for a


nd cord types with “W” in the type designation. All


other constructions not bearing the


based, and are not subject to the requirements of the Recognized Component


QMTT2 and QMTT3 Programs described below. Cords bea


ring the “


-


R” suffix such


as type SPT-2-R or SJT-R shall have the insulation and jacket compound


procedure described. The compound does not need to be covered under either


QMTT2 or QMTT3 unless the cord type also contains the ?W? suffix.




Recognition Program (QMTT2) - Under the Recognition Program for Compounds


(QMTT2), the manufacturer purchases Recognized compounds from an outside


supplier that are Recognized under the QMTT2 category. To confirm if a


compound is acceptable for the applicable cable rating(s), the Field


Representative is to reference the Online Certifications Directory to confirm


that the compound exists and is suitable for the specific type ratings.


Products not employing a Recognized compound, if required by the Procedure,


shall be held, and a Variation Notice shall be written to document the


situation.



Unlisted Component Program (QMTT3) - Under the Unlisted Component Program,


manufacturers have been granted authorization to formulate their own


compounds. To verify if a compound is acceptable, the Field Representative


shall reference a separate volume under the manufacturer's Follow-Up Service


Procedure for Flexible Cord or a separate file/volume that has been issued to


the manufacturer under the CCN


Procedure described. Cords not manufactured using the unlisted component


compound described in the Procedure shall be held and a Variation Notice shall


be written to document the situation




Subject 62


8


Issued: 2011-08-12


Procedure-described compounds - The compound used on cord


s marked with a “


-


R”


suffix (such as SPT-2-


R) is procedure described. Cords with a “


-


R” suffix that


are not manufactured using the compound described in the Procedure shall be


held and a Variation Notice shall be written to document the situation.





Reprocessed Thermoplastic Insulating/Jacketing Materials



L19.



Bleeder stock is insulating or jacketing material that has already been


processed through an extruder at least once. Bleeder stock used for


insulating or jacketing cable shall not contain any copper or other conductive


materials. Paragraphs a - c describe the only forms of bleeder stock


reprocessing currently authorized by Underwriters Laboratories Inc. It should


be noted that reprocessed thermoplastic material shall not exceed twenty five


percent (25%) by weight of the material being fed into the hopper, and shall


be thoroughly mixed with the virgin material. Use of up to 50% reprocessed


compound by weight, for cable jackets for general applications only (reference


paragraph ?c? below) is permitted only


if authorized in the Follow-Up Service


Procedure.



a.




stock obtained from the manufacturer's own production, that is


granulated while still hot at the extruder and then immediately put


back into the hopper of the extruder. Compounds reprocessed in this


manner are acceptable for any use for which the original compound is


authorized.



b.




and allowed to cool is acceptable for any use for which the original


compound is authorized, provided the bleeder stock is segregated by


compound and continuously identifiable until reused.



c.



Insulation stripped from cables is acceptable for use only as a


jacketing compound on cable in which the jacket is non-integral and


where no specific performance requirements are specified for the


jacket (such as


resistant


-


R” suffix,


etc.). Jackets employing reprocessed compound are intended for use


only where generic requirements are specified for the jacket.



L20.



Paragraphs a - c above apply only to thermoplastic insulating/jacketing


materials. Underwriters Laboratories Inc. does not authorize the reprocessing


of either thermoplastic elastomers (TPE) or of pure thermosets.



L21.



Please not


e that this applies to both “in


-


house” reprocessed compounds,


and compounds that are reclaimed insulation and jacket material (herein


defined as “reclaimed” compounds) sent to external reclaiming companies (or


sister facilities that perform this service).



L22.



Manufacturers are required to request authorization for both the use of


reprocessed compound in the range of 25 to 50% by weight, and for reclaiming


operations not conducted at the original manufacturing location for the


reclaimed products. Special instru


ctions placed in the Subscriber?s Follow


-Up



Subject 62


9


Issued: 2011-08-12


Service Procedure will authorize the use of the reprocessed compound and/or


the reclaiming operation.



L23.



Manufacturers utilizing both in-house reprocessed and reclaimed


compounds must specify the ratio of virgin and reprocessed compounds on their


production records, reel tags, or other corresponding production data. In


addition, reprocessed and reclaimed compounds of a particular temperature


rating (e.g., “PVC 90


?



C”) must be noted. For both types, manufacturers mu


st


specify in their production specifications the mixture ratio and temperature


rating(s). Suppliers of pre-mixed reclaimed/virgin compounds must specify this


same information as part of their shipping documentation.



Scrapping of Flexible Cord With a Reference to UL



L24.



The following defines the various means that UL considers acceptable in


order to render rejected, surface printed Flexible Cord unusable:



a.



Cord cut into short lengths [maximum 10 ft. (3 m)]. These lengths


are not to be disposed of in neat bundles, but rather, they are to


be disposed of by means that will cause entanglement of the short


lengths.



b.



Cord, including coils, severely compressed or compacted.



c.



Insulation stripped from the conductor.



d.



Cord of various constructions randomly assembled and bailed. It is


intended that all cord be removed from cartons or reels and all ties


removed. The turns of cord must be sufficiently separated in the


container to cause complete entanglement of the cord and thus


destroy the integrity of the original coil.



e.



Cord of various constructions processed as in


and sent to a reclaimer. Employing this method, the manufacturer


must maintain his own and copies of his reclaimer's scrap weight


records for examination by the Field Representative.



f.



Pouring printing ink on rejected coils, reels and lengths of cable


soaking the cable surface and thereby obliterating any reference to


UL, then hardening and binding the scrap cables to each other,


making the cable unusable.



L25.



If the Field Representative encounters an alternate scrapping method


being employed by the manufacturer which is not authorized in the Follow-Up


Service Procedure, the Field Representative shall document the situation on a


Variation Notice and request that the manufacturer contact the Responsible


Office within 15 days, to have the alternate method evaluated and, if found


acceptable, included in the Procedure.




Spark Testing of UL Labeled Production



L26.



Since UL 62 requires Spark Testing as a condition for labeling, Field


Representatives are required to review the manufacturer's Spark Testing



Subject 62


10


Issued: 2011-08-12


equipment and testing procedure during each inspection to determine compliance


with the requirements specified in the


UL 62. Review of the equipment shall include a review of calibration records


and function check documentation. The misuse of Spark Testing equipment and


procedures has been seen to consist of one or more of the following items:



a.



Voltage below that required.



b.



Sparking not done at the last operation before twisting, jacketing,


packaging, or reeling for shipment.



c.



Spark testers not switched on by the operator for any reason.



d.



Spark testers in poor operating condition, those that have not been


calibrated for voltage and sensitivity since installation in excess


of one year.



e.



Insufficient bead-chain spacing or missing sections of bead- chains.



f.



Conductors of insulated wire not grounded at either their take-up or


pay-off reel.

L27.



Manufacturers are required to maintain in good condition, adequate and


sufficient facilities and equipment for conducting the required tests. Should


the Field Representative question the suitability of the Spark Testing


equipment or testing procedure, the situation is to be documented on a


Variation Notice and the Field Representative will be within his/her authority


to withhold labeling of the product until the manufacturer institutes


corrective action.





FIELD REPRESENTATIVE'S COUNTERCHECK PROGRAM



Sample Selection Requirements and Special Inspection Instructions



General



L28.



At each visit to the factory the Field Representative shall be allowed to


see all Flexible Cord that bears or is intended to bear the Listing Mark, and


shall then select representative samples.



L29.



The Follow- Up Service Procedure specifies the type or types of Flexible


Cord on which the use of Listing Marks (labels) has been authorized. The Field


Representative shall assure that type designations currently being UL labeled



Subject 62


11


Issued: 2011-08-12


at the factory, or submitted for UL inspection, are authorized in the Follow-


Up Service Procedure.



L30.



The Field Representative shall examine labeled production and all


production intended to be labeled for all of the construction details,


dimensions, ratings and markings specified in UL 62, the Follow-Up Service


Procedure description, these Follow-Up and Inspection Instructions, the


Standard for Wire and Cable Test Methods, UL 2556(see also Table L4), and


shall witness the tests specified in Table L2.



L31.



The Field Representative is required to inspect and report upon randomly


selected samples. These samples shall not be taken from a lot which other


samples have been taken during a previous inspection, unless the lot was


previously rejected, has been culled (sorted) and reworked, and is resubmitted


for reinspection. The actual number of coils to be taken in individual cases


may necessarily vary somewhat according to conditions, but the Field


Representative shall follow the outline given in Table L4 and the instructions


in the paragraphs that follow the table.



L32.



The number of samples selected by the Field Representative shall be


proportional to the amount of Flexible Cord available for inspection. Select


one (1) sample for every 7,500 ft. (2.286 km) or less of two types (or one


type if only one type and one temperature rating is available for selection)


of Flexible Cord available when selected in accordance with L33 and Table L1.


A minimum of three (3) samples shall be selected per type at each visit, but


the maximum number of initial samples selected per type shall not exceed nine


(9). Each sample shall be selected from a different coil or reel.



L33.



The grouping of cord types is shown in Table L1. If available, the Field


Representative shall select samples from different groups. If samples within


one group are selected, samples of different temperature rating and options


(oil, weather resistant) shall be selected.

L34.



Samples selected for examination shall not be less than 15 ft. (4.6 m) in


length. Table L2 specifies the tests/examinations to be witnessed by the Field


Representative. For the Detailed Examination, the items shown in Table L3 are


to be reviewed, where applicable. Use Table L4 as a guide for acceptance or


rejection of a lot based on examination results.



L35.



If all of the samples examined show acceptable results, the entire lot is


acceptable with respect to that item. If any sample is nonconforming,


additional samples from different coils or reels shall be selected in


accordance with Table L4 and inspected. The lot as a whole may be accepted or


rejected in accordance with Table L4. For lots accepted, coils or reels from


which acceptable results were obtained may be labeled as being acceptable.


Reference is to be made to paragraphs L62 and L63 that provides additional


instructions regarding how a physical properties nonconformance is to be


treated. The manufacturer may then make a thorough review of the rejected


lot(s) and reject all individual coils or reels which do not comply with the


requirements, after which the remainder of the lot(s) may be submitted for


inspection and if found to be acceptable by the Field Representative, labeled.



L36.



The Field Representative shall note that all tests shown in Table L2 may


not be applicable for the given Flexible Cord under inspection. The Field


Representative shall reference the Construction Tables that appear in UL 62,


which define the construction and test performance requirements for each


Flexible Cord type. The list of tests shown in Table L2 shall be compared


against the Construction Table for the Flexible Cord type under inspection to


determine which tests in Table L2 are applicable. As an example, if a Type


SJT Flexible Cord was selected for inspection then tests 1



8 and 11 of Table


L2 are applicable. Test 9 (Tightness of Insulation) and Test 10 (Flexibility


of Braid) do not appear in the Construction Table for Type SJT. The Field
