( M/ ?% f9 i/ `: U' I' h/ y# M; y2 nQuestion:
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
( B! o" C/ f  y* ntechnical 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
) @+ d; G2 H6 y5 j6 Boptions for component descriptions, depending on the type of disk drive:
$ U/ s/ l. w7 f/ ]/ S* F& y4 E1. 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

2. Laser based drive - The parts list should state: "Mfr: Company A or equivalent", and
4 N% m) d- f+ L8 ~"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
