UL Traceability Requirements

感觉

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.

Printed wiring board assemblies (category ZPVI2)
Overview
This program provides traceability for printed wiring board
assemblies. It covers materials and components of assembled
printed wiring boards, including a board itself, when these can only
be identified at a board assembly location. This program is used
when printed wiring boards are assembled remotely from an endproduct
manufacturing location and traceability of a board or its
components is a concern. It is intended to address traceability of a
UL Recognized board and/or components only. All other aspects of
design, spacings, etc., are evaluated as part of the UL investigation
of end-use products.
Method of traceability
An assembler is required to keep records to trace the identity of all
materials and components from receipt through storage, inventory,
withdrawal, assembly, packaging and shipping. Printed wiring
assemblies covered under the category ZPVI2 are identified by an
assembler’s name and UL code designation on a part, shipping
container or included specification sheet. Relevant material and
component manufacturer name and type designations are marked
on a part, shipping container or accompanying documentation. In
addition, assemblies covered under this program will also bear the
UL Recognized Component Mark.

Wiring harnesses (category ZPFW2)
Overview
This program provides traceability for wiring harnesses that are
assembled at off-site locations and intended for use as factory
installed components at an end-product manufacturing facility. They
are defined as components consisting of two or more wires joined
electrically and/or mechanically, and may include connectors, plugs,
strain reliefs, splices, etc. When assembled at an off-site location,
traceability for components used to construct a wiring harness is
not possible at an end-product factory location. This program can
be used to provide this traceability. Each wiring harness is normally
constructed in accordance with a harness diagram and is generally
designed for a specific application that is indicated on a diagram
or carton marking. These wiring harnesses are not intended for
field installation. An assembly consisting solely of a cord set, power
supply cord or power supply cord attached to an appliance such as
a motor is not eligible for coverage under this program.
Method of traceability
An off-site fabricator assembles a wiring harness in accordance with
a harness diagram, print or other specification from an end-product
manufacturer that details construction elements and components
to be used in assembling a harness. A harness manufacturer
will assemble a harness in accordance with these specifications
and, provided that a wiring harness is in compliance with these
specifications, it may be shipped with the UL Mark. Traceability for
these construction elements is further determined at an end-product
manufacturing location and involves verifying that these features
comply with an end-product Follow-Up Services procedure.
The UL Recognized Component Mark on the smallest bundle or unit
container in which a product is packaged is the only method used
to identify wiring harnesses manufactured under the UL Recognition
and Follow-Up Service programs.

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
