Introduction


NM-300-1:2002



This part of MERCOSUR Standard was based on ISO 8124-1:2000, and in the EN 71-1:1998 related to


acoustics: in


the


requirements


and


test


methods.


Also


were


included


current


general


requirements


and


test methods on national standards of member states, specifically the NBR 11786:1998, and included a


comparative chart for testing between several standards.


However, it shall not be construed that a toy manufactured in compliance with this part of MERCOSUR


Standard will be in full compliance with relevant national toy safety requirements in the market where the


product is intended to be distributed. The user of this part of MERCOSUR Standard is therefore advised to


be aware of relevant national requirements.


Compliance with the requirements of this part of MERCOSUR


Standard


will


minimize


potential


hazards


associated


with


toys


resulting


from


their


use


in


their


intended


play


modes


(normal


use)


as


well


as


unintended play modes (reasonably foreseeable abuse).


This part of MERCOSUR Standard


will


not,


nor


is


it


intended


to,


eliminate


parental


responsibility


in


the


appropriate selection of toys. In addition, this part of MERCOSUR Standard will not eliminate the need for


parental supervision in situations where children of various ages may have access to the same toy(s).


This part of MERCOSUR Standard includes as normative the Annex B



Safety-labelling guidelines and


manufacturer's markings. As informative the Annex A

NM-300-1:2002




Safety of toys


Part 1: General, mechanical and physical properties


1


Scope


The


requirements


in


this


part


of


MERCOSUR


standard


apply


to


all


toys,


i.e.


any


product


or


material


designed or clearly intended for use in play by children under 14 years of age. They are applicable to a toy


as it is initially received by the consumer and, in addition, they apply after a toy is subjected to reasonably


foreseeable conditions of normal use and abuse unless specifically noted otherwise.


The


requirements


of


this


part


of


MERCOSUR


standard


specify


acceptable


criteria


for


structural


characteristics of toys, such as shape, size, contour, spacing (e.g. rattles, small parts, sharp points and


edges, hinge-line clearances) as well as acceptable criteria for properties peculiar to certain categories of


toy


(e.g.


maximum


kinetic


energy


values


for


non



resilient-


tipped


projectiles,


minimum


tip


angles


for


certain ride-on toys).


This part of MERCOSUR standard specifies requirements and test methods for toys intended for use by


children in various age groups from birth to 14 years. The requirements vary according to the age group


for which a particular toy is intended. The requirements for a particular age group reflect the nature of the


hazards and the expected mental and/or physical abilities of the child to cope with them.


This part of MERCOSUR standard also requires that appropriate warnings and/or instructions for use be


given on certain toys or their packaging. Due to linguistic problems that may occur in different countries,


the wording of these warnings and instructions is not specified but given as general information in annex B


(normative). It shall be noted that different legal requirements exist in many countries with regard to such


marking.


This part of MERCOSUR standard does not purport to cover or include every conceivable potential hazard


of a particular toy or toy category. Except for labelling requirements indicating the functional hazards and


the age range for which the toy is intended, this part of MERCOSUR standard has no requirements for


those


characteristics


of


toys


that


represent


an


inherent


and


recognized


hazard


that


is


integral


to


the


function of the toy.


NOTE



An example of such a hazard is the sharp point necessary for the proper function of a needle. The needle is


a


hazard


that


is


well


understood


by


the


purchaser


of


a


toy


sewing


kit,


and


the


functional


sharp


point


hazard


is


communicated to the user as part of the normal educational process as well as at the point of purchase by means of


cautionary labelling on the product’s packaging.



As


a


further


example,


a


toy


scooter


has


inherent


and


recognized


hazards


associated


with


its


use


(e.g.


instability


during


use,


especially


whilst


learning).


The


potential


hazards


associated


with


its


structural


characteristics (sharp edges, pinch hazards, etc.) will be minimized by compliance with the requirements


of this part of MERCOSUR standard.


However, taking into account the reference resolution given in MERCOSUR


54/92 concerning safety of


toys, this standard is not apply to:


1)


Christmas decorations and other parties, including children, with purpose purely ornamental;


2)


models with small scale, type hobby or craft, propulsion or not, assembled or not, in the final product


has not primarily value of toy (for example: decorative folk dolls, soldiers collection, to build models,


etc.);


3)


installation of permanent equipment, intended for use in public playgrounds or adventures;


4)


elements


and


sports


equipment


Regulated


(those


with


materials,


size


and


weight


set


in


each


regulation sports);


NOTE



It is acknowledged that often there is a subtle difference between, say, a musical instrument or sports article


and


its


imitation


toy.


In


these


cases,


the


intention


to


use


expressed


by


the


manufacturer


or


distributor,


and


the


normal use and abuse reasonably foreseeable determine if the article is an imitation toy or not.

exceeding


435 mm;


15)


video games that can be connected a display of video and fed by a tension over 24 volts;


16)


soothers of childcare;


17)


faithful imitation of firearms;


18)


jewels of fantasy aimed at children, except those that are part of a disguise or fantasy and the sets to


construct them (see D1);


19)


sunglasses, except for too many small to be used by a child;


20)


auxiliary


equipment


that


is


used


for


flotation


in


waters

22)


articles for children who are not functionality offered with a playful additional or subsequent to its main


use;

assessed


to


determine


whether


it


presents


an


unreasonable


risk


of


injury,


taking


into


account


the

and


including


96


months


that


by


reason


of


their


function (e.g. functional toy scissors and functional toy tool kits) necessarily include a sharp edge and


that do not include any non-functional sharp edges are exempt from 4.6 provided that the packaging


carries a warning (see B.2.12 for guidance).


4.6.3

protective caps that are used shall be subjected to the compression test in 5.25.7, regardless of whether


or


not


the


protective


cap


is


accessible


to


flat-surface


contact


during


the


appropriate


test(s)


in


5.25


(reasonably


foreseeable


abuse


tests).


Protective


caps


shall


also


be


subjected


to


5.25.5


(torque

Points (see D.12)


4.7.1


Accessible sharp points


a)


Accessible points on toys intended for children under 97 months, shall not be hazardous sharp points


when tested according to 5.9 (sharp point test).


If


an


accessible


point


fails


the


sharp


point


test


as


given


in


5.9,


the


point


shall


be


assessed


to


determine whether it presents an unreasonable risk of injury taking into account the foreseeable use


and intended age grade of the toy.


Points of pencils and similar drawing implements are not considered as sharp points.


16



NM-300-1:2002




b)


Potentially sharp points shall be considered non-accessible if they lie adjacent to a surface of the test

whose


largest


cross-sectional


dimension


is


2


mm


or


less


and


that


do


not


necessarily


present


a


sharp


point


when


tested


in


accordance with 5.9, are considered to be potentially hazardous sharp points. They shall therefore be


assessed to determine whether they present an unreasonable risk of injury, taking into account the


foreseeable use and intended age grade of the toy.


4.7.2


Functional sharp points


a)


Toys


intended


for


children


up


to


and


including


36


months


shall

and


its


salts,


pentachlorophenol


in


toys,


wood and wood components of certain toys).


4.8


Projections (see D.13)


If


a


projection


presents


a


potential


skin


puncture


hazard,


the


projection


shall


be


protected


by


suitable


means, such as turning back the end of a wire, or by affixing a smoothly finished protective cap or cover,


which effectively increases the surface area for potential contact with the skin. The protective cap or cover


shall not become detached when tested according to 5.25.6.4 (tension test for protective components).


Toys


intended


to


be


repeatedly


assembled


and


taken


apart


shall


have


the


individual


pieces


and


fully


assembled


articles,


as


shown


on


packaging


graphics,


instructions


or


other


advertising,


evaluated


separately.


The requirements for the assembled toy do not apply to toys where the assembling makes up a significant


part of the play value of the toy.


Since


this


requirement


relates


to


hazards


arising


from


a


child


falling


onto


a


toy,


only


vertical


or


nearly


vertical


projections


are


required


to


be


evaluated.


The


toy


shall


be


tested


in


its


most


onerous


position.

from


sharp


edges


and


sharp


points


when


tested


in


accordance


with


5.8


(sharp


edge


test)


and


5.9


(sharp


point


test).


Furthermore,


if


the


protective


components


are


removed


by


the


tension


test,


the


spokes


shall


have


a


minimum


diameter


of


2

Test methods


5.1


General


The


test


methods


specified


in


clause


5


shall


be


used


to


determine


the


compliance


of


toys


with


the


requirements of this part of MERCOSUR standard.


The tests in 5.2 through 5.24 apply to particular types of toys as specified in the requirements of clause 4.


The objective of the tests in 5.25 is to simulate reasonably foreseeable abuse and damage to which the


toys may be subjected. The test methods are for use in exposing potential hazards that would result from


the reasonably foreseeable abuse and damage of toys intended for children.


Certain test methods have been established for ages


?



?



?



from birth up to and including 18 months


from 19 months up to and including 36 months and


from 37 months up to and including 96 months of age.


29



NM-300-1:2002



If a toy is marked, labelled, advertised or otherwise intended for children of ages spanning more than one


of these age groups, the toy shall be subjected to the test(s) providing the most stringent requirements.


If a toy or its packaging is not age-labelled in a clear and conspicuous manner, or (based on such factors


as marketing practices and the customary patterns of usage of a toy by children) is inappropriately age-


labelled


and


is


intended


or


appropriate


for


children


up


to


and


including


96


months,


it


shall


also


be


subjected to the most stringent test requirements.


If


during


a


test


the


toy


has


been


materially


affected,


e.g.


by


a


clamp


or


similar


test


equipment,


further


relevant testing shall be carried out on a new toy.


Unless


otherwise


specified


in


the


test


method,


each


sample


shall,


prior


to


testing,


be


subjected


to


a


temperature


of


21


?


C


?



5


?


C


for


at


least


4


h.


Textile


toys


and


textile


soft- filled


(stuffed)


toys


shall


be


conditioned


at


a


temperature


of


21


?


C


?



5


?


C


and


65


%


?



10


%


relative


humidity


for


at


least


4


h.


The


testing shall commence within 5 min after the toy has been removed from the preconditioning atmosphere.


Toys reasonably intended to be assembled by an adult and not intended to be taken apart by a child shall


be tested only in the assembled state if the packaging and the assembly instructions prominently indicate


that the article is to be assembled only by an adult.


In situations where a test procedure may be applied in more than one way to a toy test component, the


point (or direction) of force (or torque) application which results in the most onerous conditions shall be


used.


5.2


Small parts test (see 4.3.2, 4.4, 4.18.2 and 4.25)


Place the toy, without compressing it and in any orientation, into the cylinder as shown in Figure 13.


Repeat the procedure with any removable component of the toy and any component liberated after testing


according to 5.25 (reasonably foreseeable abuse tests).


Determine


whether


the


toy


or


any


removable


component


or


liberated


component


fits


entirely


within


the


cylinder.

Position and clamp the test template A shown in Figure 14 so that the axis of the slot is essentially vertical


and the slot is unobstructed at its top and bottom openings.


Orientate the toy to be tested in a position which would most likely permit the entry of the toy through the


slot in the test template. Place the toy in the slot in the orientation stated so that the force on the toy is only


the force due to its mass.


Determine whether any part of the toy penetrates past the full depth of the cavity of the test template.


Repeat


the


procedure


for


toys


with


nearly


spherical,


hemispherical


or

Sharp edge test (see 4.6 and 4.9)


5.8.1


Principle


A self-adhesive tape is attached to a mandrel which is then rotated for a single 360°


revolution along the


accessible edge being tested.


The tape is then examined for the length of cut.


5.8.2


Apparatus


The apparatus shall be as illustrated in Figure 18.


5.8.2.1


Mandrel made of steel


The


test


surface


of


the


mandrel


shall

and


shall


have


a


surface


roughness Ra not greater than 0,40 ?


m when measured in accordance with ISO 4287. This surface shall


have a Rockwell C scale hardness of not less than 40 when measured in accordance with ISO 6508-1.


The diameter of the mandrel shall be 9,35 mm


?

Edge test apparatus


5.8.3


Procedure



Ascertain that the edge to be tested is accessible by the method described in 5.7 (accessibility of a part or


component).


Support the toy in such a manner that the accessible edge to be tested does not bend or move when the


force of the mandrel is applied. Ensure that the support is not less than 15 mm from the edge to be tested.


If part of the toy has to be removed or disassembled in order to test a particular edge, and as a result, the


rigidity of the edge being tested is affected, support the edge so that its stiffness approximates the edge


stiffness in the assembled toy.


Wrap the mandrel with one layer of the tape to provide sufficient area for performing the test.


Place the taped mandrel such that its axis is at (90


?



5)


?



to the line of a straight edge, or (90


?



5)°


to a


tangent at the test point of a curved edge, and the tape is in contact with the sharpest part of the edge (i.e.


the worst-case situation) when the mandrel is rotated one full revolution (see Figure 18).


Apply


a


force


F


of


N


to


the


mandrel,


3


mm


from


the


leading


edge


of


the


tape,


and


rotate


the


mandrel


360°



about


its


axis


against


the


edge,


ensuring


that


no


relative


motion


occurs


between


the


mandrel and the edge during rotation of the mandrel. If this procedure causes the edge to bend, apply the


maximum force that will not cause the edge to bend.


Remove the tape from the mandrel without enlarging any cut in the tape or causing any score in the tape


to become a cut. Measure the length of tape which has contacted the edge during the test. Measure the


length of tape that is cut, including any intermittent cuts. Calculate the percentage length of the tape which


has


been


cut


during


the


test.


If


this


is


more


than


50


%


of


the


contact


length,


the


edge


is


a


potentially


hazardous sharp edge.

A point tester is applied to an accessible sharp point and it


is


observed


whether


or


not


the


point


being


tested penetrates a specified distance into the sharp point tester. Depth of penetration of the point being


tested determines sharpness. If the point can contact a sensing head that is recessed a distance of 0,38

5.9.3


Procedure



Ascertain that the point to be tested is accessible by the method described in 5.7 (accessibility of a part or


component).


Support the toy to be tested in such a manner that the point does not move during the test. In most cases


it will not be necessary to support the point directly; however, if necessary, support at not less than 6 mm


from the point to be tested.


If part of the toy has to be removed or disassembled in order to test a particular point, and as a result, the


rigidity of the point being tested is affected, support the point so that its stiffness approximates the point


stiffness in the assembled toy.


Adjust the point tester by loosening the locking ring and rotating it so that it moves toward the indicator


lamp


assembly


a


sufficient


distance


to


expose


the


calibration


reference


mark


on


the


barrel.


Rotate


the


gauging cap clockwise until the indicator lamp lights. Rotate the cap anticlockwise until the sensing head


moves a distance of 0,12 mm


?


0,02 mm from making contact with the dry cell, as shown in Figure 19.


NOTE



Where the gauging cap includes micrometer markings, the distance may be readily achieved by rotating the


cap


anticlockwise


until


the


appropriate


micrometer


marking


corresponds


with


the


calibration


reference


mark.


The


gauging cap may now be locked in this position by rotating the locking ring until it fits firmly against the cap.


Insert the point, in the most onerous direction, into the cap slot and apply a force of



to depress the spring as far as possible without shaving the point on the edges of the slot or extruding the


point through the the point being tested penetrates a distance of 0,5 mm or more into the gauging


slot, causing the indicator lamp to light, and the point under test maintains its original shape while under a


force of


, the test point is a potentially hazardous sharp point.
