specifying manufacturer’s name and type number for each component?
; N4 e+ W; c6 f1 |6 k% ^! uDecision:
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
& @( I% I  c3 a8 psample tested. The description should also include the technical data (input voltage
rating, load current rating, flammability rating of the bezel), standard, and mark of
4 k& X4 B. f1 H% x4 Jcertifying 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
