如何规避灼热丝测试？

IEC60335-1，

30.2.3 Appliances that are operated while unattended are tested as specified in 30.2.3.1 and
30.2.3.2. However, the tests are not applicable to
– parts supporting welded connections;
– parts supporting connections in low-power circuits described in 19.11.1;
– soldered connections on printed circuit boards;
– connections on small components that are mounted on printed circuit boards;
– parts within 3 mm of any of these connections.
NOTE Examples of small components are diodes, transistors, resistors, inductors, integrated circuits and capacitors not directly connected to the supply mains.

– parts supporting welded connections;
支撑焊接的连接能不能给我一个实例？？让我更好的理解
– soldered connections on printed circuit boards;
是不是说塑胶壳碰到了PCB上的焊点，也不需要做灼热丝测试？？

离拔插端子距离小于3MM，需要做灼热丝吗？？

需要做，只是做550就可以，

远离足够距离就可避开.

这个是指碰焊，不是普通的焊接

如果你的塑胶壳不是用来支撑带电部件的,只要做550度就行了,如果是用来支撑带电部件的,就要做750度了.
