BRIEF HISTORY
The IS0 Recommendation R 727, Socket fittings for pipes under pressure - Unplasticized
polyvinyl chloride (PVC) fittings with plain sockets - Metric series, was drawn up by Technical
Committee ISO/TC 5, Pipes and fittings, the Secretariat of which is held by the Association Suisse
de Normalisation (SNV).
Work on this question by the Technical Committee began in 1961 and led, in 1965, to the
adoption of a Draft IS0 Recommendation.
In February 1967, this Draft IS0 Recommendation (No. 1155) was circulated to all the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial nature, by
the following Member Bodies :
Argentina Hungary Portugal
Australia India Spain
Belgium Ireland Sweden
Canada Israel Switzerland
Chile Italy Thailand
Czechoslovakia Japan Turkey
France Netherlands U.A.R.
Norway U.S.S.R.
Germany
Greece Poland Yugoslavia
One Member Body opposed the approval of the Draft
United Kmgdom
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council
which decided, in May 1968, to accept it as an IS0 RECOMMENDATION.
