RE: Cable Harnesses and Product Safety (UL1950/CSA C22.2 no. 950)
Hi Paul, For wire: CSA/UR Source: type of wire, gauge, rated voltage, max temperature, flammability rating, For shrinkable tubing: CSA/UR Source: material, rated voltage, flammability rating, max temperature, thickness You should get also a Declaration of Conformity from the cable harnesses' vendor that states all lot complies with your specs and you perform a follow-up procedure for part traceability on-site. The DoC has a spec sheet attached to it indicating manuf name, part number, date of manuf., manuf. names or UL/E # and CSA/LR # for wiring and sleeving, especially when wiring/sleeving source is changed. All lot or the package must be labeled with outside vendor' s name, part/code number, date of manufacturing, rev, stamped "verified/inspected by QC", easy to trace by your QC dept. and inspect by your product NRTL's auditor. These thoughts reflect my opinion only, I' m willing to get other people' opinions into this problem.

RE: Cable Harnesses and Product Safety (UL1950/CSA C22.2 no. 950)
I would state the requirements (UL Recognized) for the wire, heat shrink, etc. on the print somewhere. You may want to also set up some sort of "certification" process with your supplier, that is, you and your supplier work up a certification document stating that components used on your assembly are constructed using UL Recognized parts. This cert is completed and shipped with each shipment of your cables. We presently do this on some of our components that appear on the UL Test Report, such as transformers, finished plastic parts. It has pleased two of our UL field inspectors over the past years, so far so good! Good Luck! -Original Message- From: Hare, Paul [mailto:ph...@pirus.com] Sent: Wednesday, March 14, 2001 6:05 PM To: emc-p...@ieee.org Subject: Cable Harnesses and Product Safety (UL1950/CSA C22.2 no. 950) I use an outside vendor to assemble various cable harnesses for my products.

RE: Cable Harnesses and Product Safety (UL1950/CSA C22.2 no. 950)
Paul - If you specify on your drawings that the harnesses (cables) are to be UL R/C (or Listed) and CSA Certified, your vendor should place the required markings or agency labels on the packaging or product as specified in their UL agreement. You need to have the packaging available when the FUS inspector comes around, and the markings/labels should be all that the inspector needs to see. Jim Lyons James W.

RE: Cable Harnesses and Product Safety (UL1950/CSA C22.2 no. 950)
Call out requirements for recognized material VW-1 etc on the drawing. Then have the vendor mark the cables with their recognition mark, either toe tags or on the box. Show that to the inspector just like you would any recognized part. But have control of your vendor - you should have some feedback mechanism that says you approve the material before he uses it, again just like any other second source component.
