Decision confirmed
by CTL at its 42nd
meeting 2005 in
Cancun
Question:
Within an IECEE CB Report for an end product that contains a component disk drive(s)
(e.g., CD-ROM, CD-RW, DVD, Hard, Floppy, Tape), if the disk drive(s) has its own
certification to IEC 60950 (-1), is it acceptable to identify such a critical component by
technical data, standard, and mark(s) of conformity, as in the example below, without
specifying manufacturer’s name and type number for each component?
Decision:
For component disk drives covered by a CB Test Report and Certificate, there are two
options for component descriptions, depending on the type of disk drive:
1. Non-laser based drives – The parts list should state "Mfr: Company A or equivalent," and
"Model: Model B or equivalent," so there is traceability for the construction of the
sample tested. The description should also include the technical data (input voltage
rating, load current rating, flammability rating of the bezel), standard, and mark of
certifying body/organization.
2. Laser based drive - The parts list should state: "Mfr: Company A or equivalent", and
"Model: Model B or equivalent," so that there is traceability (to IEC60950-1 and
applicable laser requirement(s)) for the construction of the sample tested. The description
should also include technical data (input voltage rating, load current rating, flammability
rating of the bezel, and, when applicable, laser classification), and standard, and indicate
that the component is covered by a CB Test Report and Certificate.

complex set of requirements to be applied, or the evaluation is part of the end product
evaluation, the manufacturer’s name and type number, in addition to the technical
information, shall be described/controlled for each component.
