BRIEF HISTORY
The IS0 Recommendation R 343, Warp Tubes for Ring Spinning and Ring Doubling
Spindles-Inch Dimensions, Tolerances and Gauges, was drawn up by Technical Committee
ISO/TC 72, Textile Machinery and Accessories, the Secretariat of which is held by the Associa-
tion Suisse de Normalisation (SNV).
Work un this question by thc Tcchnical Committee began in 1958 and led, in 1960, to the
adoption of a Draft IS0 Recommendation.
In August 1961, this Draft IS0 Recommendation (NO 449) was circulated to all the IS0
Member Bodies for enquiry. It was approved by the following Member Bodies:
Australia Germany Poland
Austria India Spain
Brazil Italy Switzerland
Chile Netherlands Turkey
Czecho Slovakia New Zealand United Kingdom
One Member Body opposed the approval of the Draft: France.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council,
which decided, in September 1963, to accept it as an IS0 RECOMMENDATION.
