以下就拿60335-1 来说

如果分不清楚就按照说明书把产品运行一下,看一下就知道了究竟是什么了,然后再去查元器件的证书看看耐久的次数是不是符合要求

在这里要指出的是光从外观是看不出这个元器件是thermostat 还是 self-resetting thermal cutout的. 2 F1 Z, O* K/ [1 w. H6 U" P
5 H( c8 Q5 R8 i( p4 a所以6楼中第一章图片是用在冰箱中的温控器,一般情况下是对的
5 |8 e4 b- P' [9 _, M+ T但是第三张图片绝对不能说是thermal cutout. 也许用在A产品中是thermal cutout但是用在B产品中就是thermostat了. 举个例子,sandwich maker(三明治炉)中很多温控器都是这个样子的.' J4 ?: E( c7 z* D+ I

判断是不是温控器是要运行产品来判断的" J/ p" I- A; T: a4 K5 }9 T4 I
$ {5 H* Z+ c3 n; f. Q( `1 i" b另外, 2楼的解释也有问题,前看下面的条款/ N9 O( }- E4 H& p
24.1.8 The relevant standard for thermal links is IEC 60691. Thermal links that do not/ N r4 v* J1 _; c
comply with IEC 60691 are considered to be an intentionally weak part for the purposes of7 a# O/ |& H1 h
Clause 19.- N. R3 x# u0 m2 n
60335-1 的A2已经修改了,所以thermal link 不一定要有证书的.
