The work of preparing International
9、 Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, a
10、lso take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Interna
11、tional Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 10897 was prepared by Technical Committee ISO/TC 29, Small fools. Annex A forms an integral part of this International Standard. ISO 10897:1996 (E)21 Scope This International Standard s
12、pecifies the dimensions, materials and manufacturing requirements, and designation of collets for tools with cylindrical shanks and their corresponding holders and nuts. For non- standardized clamping devices, such as clamping devices specified in drawings, these holders can be agreed upon between c
13、ustomer and supplier. Form A applies where a clamping range of h10 is sufficient. Form B can be used for any application without lateral cutting load. 2 Normative reference The following standard contains provisions which, through reference in this text, constitute provisions of this International S
14、tandard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below. Members of IE
15、C and IS0 maintain registers of currently valid International Standards.
