capacity

accurate

and

reliable

so

as

to

be

in

accordance

with

the

national calibration rules, it is requested that the expand uncertainty of the whole capacity be 0.1

﹪

(k

＝

2) so

that it will be scientific and fair.

●

新建罐 必须经水压试验且排完水、罐内清扫后方能进行检定，即用水充装到总容量的

80%

以上，

稳定时间不少于

48

小时后方能进行检定。

Calibration can start only after water pressure test, especially after water draining off and cleaning up;

that is, the tank should be filled with water until it reaches to much more than 80

﹪

of the capacity, and

the stable situation should last more than 48 hours.

安全要求

REQUSTS FOR SAFETY

●

关闭所有进出罐的管线，做到无任 何泄露，打开所有进出人孔和通风口。

All the tubes into or out should be closed so that no leak takes place,All manholes shall be open for

acess/egress and ventilation.

●

使用的电器设备应符合防爆要求。

All the electric equipment should be in keeping with the explosion-proof rules.

●

标定人员的衣服鞋帽必须符合有关 规定，避免静电与火花的产生。

The

dress

of

calibrating

staff

should

be

in

accordance

with

the

related

regulations

in

case

that

static

electricity or sparks would happen.

●

认真检查扶梯和罐顶的护栏以及能检查到的其它附着在罐壁或罐顶的附件，确定其是否牢固，以

保证检定人员及仪器的安全。

Have an attentive check on the staircase, top bars and some other attachments on the tank wall and top,

make

sure

whether

they

are

stable,

so

as

to

guarantee

safety

of

the

calibrating

staff

and

their

instruments.

●

进罐测量时，罐内有害气体的浓度 必须符合安全规定，并得到申检单位安全部门的进罐许可。

Whenever entering the tank, esp. when the measuring beginning, the density of pernicious gas should

meet safety requirements. Note that you should be allowed access to the tank from the security service

of the application company.

●

高空作业人员应使用牢固耐磨的安全带。

People working high above the ground should use wear-resisting safety harness.
