Hello folks,
Thank you to everyone who replied with the information and further reading; it was most helpful. I'm still on the EN version of the 2nd edition which is why I hadn't spotted the update. All the best James From: James Pawson (U3C) <ja...@unit3compliance.co.uk> Sent: 07 January 2019 15:55 To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] Cable Flammability Standard Comparison Hello all, Happy new year folks, I hope 2019 brings health and happiness to you all. I'm trying to gain a better understanding of cable flammability standards. Safety standard EN 62368-1 states that, for PS2 and PS3 circuits, wire insulation flammability should meet the requirements of [ IEC 60332-1-2 and IEC 60332-1-3 ] or IEC/TS 60695-11-21. I don't have a copy of 60695-11-21 but have read that it uses a 500W flame. Does anyone have a feeling or understanding for the equivalence between 60695-11-21 and the UL 1581 test for VW-1 rating of cables? I ask because I don't see many cables with a 60332-1 or 60695-11-21 rating but lots with a VW-1 rating, for instance on PC ATX power supplies, the outputs of which are definitely PS2 and PS3 circuits. If someone could point me towards some further reading material on the subject that would be appreciated.
