The work of preparing Intematio
20、nal 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 IS
21、O, also take pari 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 Int
22、ernational Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 8739 was prepared by Technical Committee ISOTTC 2, Fastenem. This second edition cancels and replaces the first edition (IS0 8739:1986), which has been technically revised. Descrlpt

24、characteristics of full-length parallel grooved pins, made of steel or austenitic stainless steel, with pilot which have three equally spaced grooves impressed longitudinally on their exterior surface and a pilot to facilitate insertion, with nominal diameter, d, from 1,5 mm to 25 mm inclusive. The
25、displaced material to each side of the grooves forming an expanded diameter d2 which is larger than the nominal diameter d, will cause a non-positive locking fit when these grooved pins are forced into a drilled hole equal to the nominal diameter d, (see clause 4). 2 Normative references The followi
26、ng standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encour
