BRIEF HISTORY
The IS0 Recommendation R 441, Drop Wires for Mechanical and Electrical Warp Stop
Motions, was drawn up by Technical Committee ISOITC 72, Textile Machinery and Accessories,
the Secretariat of which is held by the Association Suisse de Normalisation (SNV).
Work on this question by the Technical Committee began in 1950 and led in 1956, to the
adoption of two Draft IS0 Recommendations.
These first Draft IS0 Recommendations (Nos. 127 and 128) were circulated to all the IS0
Member Bodies for enquiry, in Septembre 1956. As the results of this consultation were not
considered satisfactory, the Technical Committee presented two second Draft IS0 Recommenda-
tions, which were circulated to all the IS0 Member Bodies in September 1963, and which were
approved by the following Member Bodies:
- for Draft IS0 Recommendation No. 127:
Argentina Greece Poland
Brazil Hungary Spain
Colombia Italy Switzerland
Czechoslovakia Korea (Rep. of) United Kingdom
France Netherlands Turkey
Germ an y New Zealand
Two Member Bodies opposed the approval of the second Draft:
India
U.S.S.R.
- for Draft IS0 Recommendation No. 128:
Brazil Hungary Poland
Colombia India Spain
Czechoslovakia Italy Switzerland
France Korea (Rep. of) United Kingdom
Germany Netherlands Turkey
Greece New Zealand
One Member Body opposed the approval of the second Draft: U.S.S.R.
These two Draft IS0 Recommendations were then submitted by correspondence to the
IS0 Council, which decided, in July 1965, to accept them as an IS0 RECOMMENDATION.
