标题: 19.2测试条件？ [打印本页] 作者: Hu159357 时间: 2019-4-29 21:19 标题: 19.2测试条件？ 19.1 中有Unless otherwise specified, the tests are continued until a non-self-resetting thermal cutout operates or until steady conditions are established. If a heating element or an intentionally weak part becomes permanently open-circuited, the relevant test is repeated on a second sample. This second test shall be terminated in the same mode unless the test is otherwise satisfactorily completed. # ^6 |% c n+ M5 u- O

而在19.2中又有 Appliances with heating elements are tested under the conditions specified in Clause 11 but with restricted heat dissipation. - _9 U6 _- b* t4 ^19.2中写按11章测试条件测试，测试时间30min（此时间针对IEC 60335-2-23的产品中手持式器具）是否可以理解成另有规定，是否不用按19.1做到稳定状态？2 n/ F7 M9 e% r9 s1 A: O+ \ 作者: guxia 时间: 2019-6-10 11:19
个人认为 conditions specified in Clause 11 包括11.7.作者: MANMANM 时间: 2019-6-11 10:39

19.2 的异常是电参数改变， 测试时间和安装方式及其他都是参考正常温升；注意特别的19.2 也要看一下。
