Cables and reaction to fire

lyledunn
Why do you suppose that the MHCLG did not feel it necessary to mandate levels of performance for cables with respect to their reaction to fire as was their prerogative under CPR?

Clearly the current non-prescriptive approach is either working or there is no significant evidence that cables and wiring systems have unduly contributed to the propagation of a fire or resulted in emissions that made a situation untenable when it would not have otherwise been. 

Further, what does it actually mean in the note in 422.2.1 that cables need to satisfy the requirements of the CPR in terms of their reaction to fire? I can find nothing specific in the CPR other than the need for CE marking and the requirements placed on the manufacturers for technical information.

    Having said all this, I realise that we are suffering from a bit of topic creep here. I am not sure what this has to do with cable fire performance. Any comments to bring it back will no doubt be welcomed by Lisa.



    I would class this as acceptable topic creep though as it's still loosely related to fire protection etc. albeit not specifically cables now... ?


    Where a conversation goes completely away from the original subject then I'd say that was definitely #offtopic
