BRIEF HISTORY
The IS0 Recommendation R 104, Ball and Rollers Bearings - Boundary Dimen-
sions, was drawn up by Technical Committee ISO/TC 4, Ball and Roller Bearings, the
Secretariat of which is held by the Sveriges Standardiseringskommission (SIS).
The proposals drawn up by the ISO/TC 4 Secretariat for the subject-matter of this
IS0 Recommendation were discussed by the Technical Committee during its fourth
meeting, held in Madrid, in May 1955, and during its Wth meeting, held in Vienna, in
September 1956; they were adopted as a Draft IS0 Recommendation.
On 15 November 1957, the Draft IS0 Recommendation (No 154) was distributed
to all the IS0 Member Bodies and was approved by the following Member Bodies:
India Spain
Austria
Bulgaria Italy Sweden
Switzerland
Burma Japan
Canada Netherlands Union of
South-Africa
Finland New Zealand
Poland United Kingdom
France
Germany Portugal U.S.A.
Romania U.S.S.R.
Hw3ary
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the
IS0 Council, which decided, in April 1959, to accept it as an IS0 RECOMMENDATION.
