IEC是否有规定电源线外露长度呢？我之前看到过最新的IEC标准，电暖器电源线外露长度不能大于1.8m.根据出自哪里呢？

不同的产品有不同要求，特标里找找。

这个要看特标，一般在25.8章节中可以找到。

IEC 60335-1:2004 25.8里面的表，表明某些线不可以长度超过2M,我之前看到的是新标准的表里，2M改成了1.8M是什么年号的IEC标准呢？

a These cords may only be used if their length does not exceed 2 m between the point where the cord or cord guard enters the
    appliance and the entry to the plug.
b Cords having the cross-sectional areas indicated in the　parentheses may be used for portable appliances if their length does not exceed 2m

这个只是对于表格中选用箔线、0.5平方和其他括号里的线径的一个前提条件而已
