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.
