20、ENISO8739:1997 ii BSI 04-1999 Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interes

21、ted 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, also take part in the work. ISO collaborates closely with the International Electrotechnical C

22、ommission (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 International Standard requires approval by at least75% of the member bodies casting a vote. Interna

23、tional Standard ISO8739 was prepared by Technical Committee ISO/TC2, Fasteners. This second edition cancels and replaces the first edition (ISO8739:1986), which has been technically revised. Descriptors: Fasteners, steel products, pins (mechanics), grooved pins, specifications, characteristics, dime

24、nsions, designation.ENISO8739:1997 BSI 04-1999 1 1 Scope This International Standard specifies the 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

25、and a pilot to facilitate insertion, with nominal diameter, d 1 , from1,5mm to25mm inclusive. The displaced material to each side of the grooves forming an expanded diameter d 2which is larger than the nominal diameter d 1will cause a non-positive locking fit when these grooved pins are forced into

26、a drilled hole equal to the nominal diameter d 1(see clause4). 2 Normative references The following 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 a

27、re subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 3269:1
