Dear Barry Thanks for your kind answer.
I know that Australia standard of glow-wire test. Because, I have some experience of glow-wire failure when I requested by test lab. in Australia last year. In the IEC 335-1 (third edition) demand tip temperature of glow-wire 750 centigrade in case of unattended appliance and current exceed 0.5mA. However, EN and Australia standard want more sever condition as 850. You mentioned that the current of connection is the main point to decide tip temperature. But I do not know what is the correct mathematics calculation method to choice glow wire tip temperature. If you know it, please tell me about.
