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...作者: songbolove 时间: 2012-1-11 20:04
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作者: lukefeng 时间: 2012-1-12 08:48
不清楚就问UL工程师,因为工程师个人看法理解都不同。。作者: Rock 时间: 2012-1-20 11:26

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作者: tony0421 时间: 2012-6-20 11:17
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。) W' i" S. u" m* e
