Dear colleagues. I have a question regarding the flammability rating of components located within a fire enclosure. We have been told by a safety approval engineer that under clause 6.4.6 of 62368-1:2014 that all combustible material within a fire enclosure and not part of a PS2 or PS3 circuit must have be V-2 or better flammability rating. For example, internal harnesses & connectors which carry low level signals between PCBs and do not carry supply voltages must have a rating of V-2 or better. Does this mean that any component within a fire enclosure regardless of location must have a minimum flammability rating of V-2 or pass the convoluted Annex S.1 test?
