The work o
4、f developing Inter- national Standards is carried out through IS0 technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental and non-governmental, in liai
5、son with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 5407 was developed by Technical Committee ISO
6、/TC 29, Small too/s, and was circulated to the member bodies in May 1980. It has been approved by the member bodies of the following countries : Australia India Austria Israel Belgium Italy Czechoslovakia Japan France Korea, Dem. P. Rep. of Germany, F.R.

9、s and tolerances 1 Scope and field of application This International Standard lays down the dimensions and tolerances of as-sintered hardmetal pellets used in heading dies. NOTES 1 As defined in IS0 3252, the term “hardmetal” may be used synonymously with “cemented carbide”. 2 In the United States,
10、the term “nib” is used instead of the term “oellet”. 2 References IS0 3252, Powder metallurgy - Vocabulary. 1) IS0 5396, Hardmetal heading dies - Terminology. 1) At present at the stage of draft.
