NOTE 1 Thermal cut-outs of the trip-free type have an automatic action, with a reset actuating member, so constructed that the automatic action is independent of manipulation or position of the reset mechanism.

u]Thermal cut-outs of the bulb and capillary type that operate during the tests of Clause 19

shall be such that rupture of the capillary tube shall not impair compliance with the

requirements of 19.13.

Compliance is checked by inspection, by manual test and by rupturing the capillary tube.

NOTE 2 Care must be taken to ensure that the rupture does not seal the capillary tube.

我想请教的就是上面红底字。这个实验如何做？割开毛细管的温控器，是割开探头部分（粗点），还是割开毛细管（细点）部分？割开以后，里面的传导介质流失掉，限温器还能起什么作用？做60335-1的CL19.5时候，就相当于干烧了，要符合CL19.3的要求，如果干烧符合要求，还加限温器做什么？

请大家说说

也许一刀下去，它断电了。

我们有一产品,油炸锅用毛细管的温控器,在香港TUV测试时是折断毛细管.有保险丝保护就行的.参考用

有道理！

此测试是在产品正常工作的情况下剪断限温器的毛细管，等毛细管内部的液体流完了，限温器就会断开，测试合格，不会断开测试失败
