dot rule 54, fire test requir for mains, is it still active?
hi all,
i am struggling to find out if dot rule 54 has been replaced by another standard, our certificate is out of date and lloyds have stated they don't regonise it, even though they tested and issued or original certificate, any help would be appreciated, thanks.
