39.2.1 The tests are to be performed with any combinations of temperature controls in the circuit and out of the circuit where such combinations may result in higher temperatures or increased risk of electric shock or ?re.
Exception: The following controls are to be left in the circuit:
a) A designated temperature limiting control [see 3.14(b)]

上面的电路内， 外什么意思？是下面的意思吗？
把温控器从电暖器的外壳的里面拿到外壳的外面， 使这个温控器不感温，从而电暖器一直加热到失效，或限温器动作。

PTC加热元件算不算温控器？

先谢谢啦

标准的意思是 任何的组合性的温控，在回路或不在回路里那个危险，按照最危险的来。
PTC加热件 不算温控
