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. ) k/ A$ z9 v8 |" y$ n

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。
