消費(fèi)者在使用 便攜式風(fēng)扇和電暖器 ( 取暖器、暖風(fēng)機(jī) ) 時普遍存在四種使用狀況：
1 ) 消費(fèi)者將風(fēng)扇和電暖器或其他物體壓在電源線上。
2 ) 消費(fèi)者將風(fēng)扇和電暖器推靠到墻邊夾到電源線。
3 ) 消費(fèi)者將風(fēng)扇和加熱器的電源線暴露在人會來回走動的地方。
4 ) 消費(fèi)者在儲存期間，電線暴露也會損壞。
“R”類就是增加以下4項測試內(nèi)容
﹥ 磨損測試 Abrasion Test
﹥ 夾擠測試 Mandrel Pinching Test
﹥ 壓碾測試 Mandrel Crushing Test
﹥ 彎曲測試 Flexing Test

一、-R型在UL62沒有定義R的名詞，僅作為區(qū)分電纜型號的代碼；（-R型需要額外增加4項測試，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明確解釋了名詞：（注：-W型需額外增加4項測試：（抗UV 720Hrs&冷彎-30℃、Insulation resistance、Permittivity and stability factor、（第四項：根據(jù)具體電纜型號選測Swelling and blistering））
5.1.7 Weather resistance – all ″W″ cords and electric vehicle cables
，歡迎拍磚

UL電線標(biāo)記與應(yīng)用 里面有說明
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.
對于"W"里面有很多條款給予了說明，可以認(rèn)為是“戶外”使用電纜
