Together with BS EN 1254-2 it supersedes BS 864-2:1983 which is declared obsolescent. The UK participation in its preparation was entrusted by Technical Committee NFE/34, Copper and copper alloys, to Subcommittee NFE/34/3, Copper and copper alloy fittings for tube and pipe, which has the responsibility to: ? aid enquirers to understand the text; ? present to the responsible European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; ? monitor related international and European developments and promulgate them in the UK.
