# t. S J1 [* n1 b/ H. S/ d请教各位大师关于UL859:2012中section 44 的温升测试方法问题。我看标准很有歧义，公司做法跟我的理解好像不一致！
3 O9 J6 A- c4 m7 a) n标准原文： s( [. R' K$ `8 q/ L3 ]
44.1.19 An electrical heating element intended for application to the hair is to be loaded with a moistened

疑问如下：
* R5 @3 @" _7 n, H. B1，直发器和卷发器的温升测试方法是一样的吗?具体步骤是怎么样的？2 j& t% C/ I6 j

2 \7 ]6 n3 J% H T4 T: X4 j2，我看标准理解是：直发器和卷发器测试方法一致，发热板上夹湿布，开始上电，直到蒸发完成且发热板表面温度达到204度时，断电；停止2分钟，期间换上第二块湿布，再次上电，直至温度达到204度，完成测试（总共测试2cycles）。这种理解正确吗？难道只做2cycles/换2次湿布就可以完成温升测试了？好像这样温度都没有达到稳定状态。

3，标准说达到204度后断电，换湿布，那么如果我们的产品发热板表面温度没有达到204度，那什么做测试？

4，为什么44.1.19中是测试2cycles，而44.1.21中却说是要一直工作到温度状态？这两个条款是针对不同产品吗？指哪些产品呢？
