取暖机、暖风机（UL1278）的插头不用带保护插头，那插头需要重新送样报备—R的线吗？

UL507有要求用到此类插头而且即将生效：
21A Fuseholders and Fused Attachment Plugs
Added Section 21A effective September 27, 2010
21A.1 In addition to the applicable requirements in this standard, a fuseholder located in the enclosure of
a unit shall comply with the Standard for Fuseholders – Part 1: General Requirements, UL 4248-1 and/or
any applicable part in the UL 4248 series standards, and a fused attachment plug shall comply with the
Standard for Attachment Plugs and Receptacles, UL 498, or the Standard for Cord Sets and
Power-Supply Cords, UL 817.
请参考具体的UL498或UL817，此类插头，UL507要求提供证书。
