求助“SJTW及以上线”这句话包含SPT-2W线吗？

新手请教：
产品是户外灯具，标准说，如果要在户外使用，电源线要是SJTW及以上线，请这句话包含SPT-2W线吗？
请问SPT-1，SPT-2，SVT和 SJT这些线有高低等级之分吗？SJTW及以上线有哪些线？
SPT-2和SJT线使用的区别在哪？
谢谢

SJT是hard usage ，SPT是No hard usage，SJT的绝缘皮要比SPT的厚。

我想了解一下，hard usage 和 no hard usage分别是指怎样的使用场所？

参考UL62中的定义：
Not-for-hard-usage cord – a cord intended for use with light equipment, classified as the lowest grade
in mechanical serviceability.
Hard-usage cord – a cord intended for use with moderately heavy equipment and for hand-held
appliances and tools, classified as the medium grade in mechanical serviceability.
Extra-hard-usage cord – a cord intended for use with heavy equipment and for hand-held appliances
and tools, classified as the highest grade in mechanical serviceability.
