BRIEF HISTORY
The IS0 Recommendation R 22 was prepared by the Technical Committee
ISO/TC 41, Pulleys and belts (including vee-belts), the Secretariat of which is
held by the Association Française de Normalisation.
It was at its Lisbon meeting in April 1953 that the Committee adopted
the resolutions on which the present Recommendation is based. From then
10 and R 20 series of preferred
on, the chosen values were taken from the R
numbers.
After the Lisbon meeting, the Secretariat circulated a first draft proposal
and subsequently a second one to take account of the few comments received
(unification of tolerances on widths for all possible constituent materials of
pulleys and belts, possibility of adopting some other correspondence than
I
provided for ordinary transmissions).
Following the circulation of the second draft proposal, an addition was
made to the footnote to the table of.widths, in an attempt to meet the only
comment received, without compromising the general agreement of the other
Member Bodies who had replied.
The draft thus amended was sent to the General Secretariat, which placed
it before all the IS0 Member Bodies as Draft IS0 Recommendation.
The following 21 (out of a total of 35) Member Bodies approved the Draft
without reserve :
