UL Traceability Requirements
当然，这个是从UL官方得到的，可惜只有英文版本。如果有同学看得困难，有问题我可以帮忙解答。个人觉得这还是很不错的一份指南。

Fabricated parts (category QMMY2)
Overview
UL’s fabricated parts traceability program covers material traceability
for molded, encapsulated, potted and other fabricated plastic parts.
This program is intended to provide quick verification of material
identity through markings on a fabricated part.
Component specifications are noted in individual end-product UL
Follow-Up Services procedures. An end-product manufacturer must
pay particular attention to the UL Follow-Up Services procedure to
be sure that the component specifications are not compromised
and continue to meet UL requirements, especially when molders or
fabricators use additives, regrinds and recycled plastics.
Method of traceability
Traceability is provided by means of identification markings on a part,
shipping carton or accompanying specification sheet that includes
the following information:
• UL-assigned designation
• Name of molder/fabricator
• Factory location, when more than one factory location is used
• Part identification
• Date of molding or fabrication
• Material manufacturer’s name and grade designations.
This may be a code mutually agreed upon between an
end-product/designated-party manufacturer and a
molder/fabricator.

Processed wire (categories ZKLU, ZKLU2, ZKLU7 and ZKLU8)
Overview
This program provides traceability for various different types of wire/
cable that have been subjected to processing subsequent to original
manufacturing and labeling. Wire in these categories originates as
insulated wire that is then cut into specified lengths with insulation
stripped from one or both ends and packaged for further processing.
The stripped ends may be soldered or tinned and may have eyelet,
ring, open spade or quick-connect terminals attached by crimping,
soldering or welding. This program can also cover wire that has been
respooled into smaller quantities.
Method of traceability
Traceability for wire that is covered under this program is through an
appropriate UL certification mark on an attached tag, reel or smallest
unit container in which product is packaged. In addition, tag-marking
information provided by an original wire manufacturer is transferred
onto tags provided by a wire processor. The certification marks
applicable to this program include:
• UL Listed processed wire
• Respooled UL Listed processed wire
• UL Classified processed wire
• Respooled UL Classified processed wire
• UL Recognized processed wire
• Respooled UL Recognized processed wire
