BRIEF HlSTORY
Addendum 1, Dimensions of the wheel holes for special applications and tolerances, to IS0 Recommendation
R 525 -1966, Bonded abrasive products ~ General features - Designation - Ranges of dimensions ~ Profiles, was
drawn up by Technical Committee iSO/TC 29, Small tools, the Secretariat of which is held by the Association Fran-
çaise de Normalisation (AFNOR).
The IS0 Recommendation R 525-1966 has been completed by the addition of two hole dimensionsd (dimen-
sions for special applications), and by the tolerances to be assigned for wheel holes. Work on this question led to the
adoption of a Draft IS0 Recommendation.
In July 1968, this Draft 1SO Recommendation (No. 1590) was submitted 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 :
Australia Ireland Sweden
Austria lsrael Switzerland
Belgium Italy Thailand
Chile Japan Turkey
Czechoslovakia Netherlands U.A.R.
France Poland United Kingdom
Germany Portugal U.S.A.
Hungary South Africa, Rep. of U.S.S.R.
India Spain Yugoslavia
No Member Body opposed the approval of the Draft.
This Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council, which decided,
in June 1969, to accept it as ADDENDUM 1 to IS0 RECOMMENDATlON R 525-1966.
