热电偶的COC

UL说要热电偶的COC， certificates of conformance , 问了几个我公司的热电偶供应商，都回答没有，哪里去找呢？ 你见过吗？
是不是要证明符合ANSI MC 96.1的声明还是？？？

求

You need to know, why UL asks for that, and if you can not understand it, then directly ask the UL engineer, and let him/her explain to you which kind of data he/she needs to evaluate...

做了这么久的UL目击测试，还真没见过UL工程师要求说需要热电偶的COC:D

不清楚就问UL工程师，因为工程师个人看法理解都不同。。

certificates of conformance ??不是certificate of conformity??

谁能解释下

hope who answer this question.

这里的COC应该是Certificate of Calibration，一般常用K型T型热电偶都是OMEGA的，他们在出货时都自带这个CoC

上面的理解有误，刚才又看了下UL对实验室的要求，这里CoC的确是CERTIFICATE OF COMPLIANCE。

具体的解释

1. The supplier of the thermocouple wire shall be required to provide a certificate of
conformance. The appropriate certificate shall be requested from the supplier when the
material is ordered (i.e. Class 1,2 or 3 per IEC 60584-2, JIS C 1602, Special Tolerances
(Limits) wire per ASTM E230 or ANSI MC96.1 Temperature Measurement
Thermocouples. The certificate shall be included with the material shipment or the
supplier shall provide an alternate means such as access to a website where the certificate
can be obtained.
