所有根据ANSI/UL 507申请 ETL Mark 的产品在 2010年9月27号之前, 必须符合以下於2007年9月27号所发布的新生效或是修正的标准条文. 新生效条文摘要如下:

14.1.1A 针对Table 14.1内，第一列与第二列所描述的电源线，必须符合Section 51B~51E的能力测试。
51B supply cord Abrasion
51C supply cord pinching -mandrel
51D supply cord crushing -mandrel
51E supply cord flexing

要求相当的高，在客户那里看到测试过程，感觉要通过这个测试，电线胶料配方要作相当大的改变才行

UL 1278电暖器标准仍有相同的要求，所以做电线的朋友们一定要早作准备啊
