消费者在使用 便携式风扇和电暖器 ( 取暖器、暖风机 ) 时普遍存在四种使用状况:

1 ) 消费者将风扇和电暖器或其他物体压在电源线上。

2 ) 消费者将风扇和电暖器推靠到墙边夹到电源线。

3 ) 消费者将风扇和加热器的电源线暴露在人会来回走动的地方。

4 ) 消费者在储存期间,电线暴露也会损坏。

“R”类就是增加以下4项测试内容

磨损测试 Abrasion Test

夹挤测试 Mandrel Pinching Test

压碾测试 Mandrel Crushing Test

弯曲测试 Flexing Test

一、-R型在UL62没有定义R的名词,仅作为区分电缆型号的代码;(-R型需要额外增加4项测试,如下:)

Cords marked with the ″-R″ suffix as indicated in Clause 6.2.4(g) shall comply with the requirements

specified for the standard cord construction in addition to those specified in Clauses 4.2.13.2 – 4.2.13.5(Abrasion、Mandrel pinching、Mandrel crushing、Flexing).Cords marked with ″-R″ shall be limited to 0.824 – 2.08 mm2 (18 – 14 AWG), and 300 V.


二:-W型:UL62明确解释了名词:(注:-W型需额外增加4项测试:(抗UV 720Hrs&冷弯-30℃、Insulation resistance、Permittivity and stability factor、(第四项:根据具体电缆型号选测Swelling and blistering))


5.1.7 Weather resistance – all ″W″ cords and electric vehicle cables

W型理解成户外阻水线,R型理解成户外耐磨线。

UL电线标记与应用   里面有说明


Similarly, cables covered for use in accordance with Articles 725, 760, 770, 800, 820, and 830 of the NEC? are investigated with respect to their application: plenum, riser, general use or restricted residential use. Suffixes to the Type designation identify the use as defined in the appropriate NEC? articles:

-P: Plenum

-R: Riser

-No Suffix, -G: General purpose

-X: Limited residential use

Some wire and cable may also have a suffix ―-LS‖ or "ST1" which means that the entire construction complies with the requirements for flame retardant, limited smoke wiring materials as evaluated per UL 83, UL 1685 or UL 2556.


对于"W"里面有很多条款给予了说明,可以认为是“户外”使用电缆
