% J( |$ d+ d  m, Q7 H. E2 |' bQuestion:
Within an IECEE CB Report for an end product that contains a component disk drive(s)
$ U* ?7 T  p+ a7 J(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:
3 H- C6 `9 B4 j4 O: q1. 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

certifying body/organization.
7 E' r5 V7 i5 \/ H+ [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
6 y! J& ^8 n& fapplicable laser requirement(s)) for the construction of the sample tested. The description
should also include technical data (input voltage rating, load current rating, flammability
