1、BRITISH STANDARD BS EN ISO 8745:1998 Grooved pins Half-length taper grooved The European Standard EN ISO 8745:1997 has the status of a British Standard ICS 21.060.50BSENISO8745:1998 This British Standard, having been prepared under the directionof the Engineering SectorBoard, was published underthe

2、authority of the Standards Board and comes intoeffect on 15 May 1998 BSI 04-1999 ISBN 0 580 29060 3 National foreword This British Standard is the English language version of EN ISO 8745:1997. It is identical with ISO 8745:1997. It supersedes BS EN 28745:1992 which is withdrawn. The UK participation

3、 in its preparation was entrusted by Technical Committee FME/9, Bolts, nuts and accessories, to Subcommittee FME/9/6, General purpose fasteners and accessories, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enqu

4、iries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Atte

5、ntion is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement international or European publications referred to in this document

6、 may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of Briti

7、sh Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

20、745:1997 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 interested in

21、 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 Commiss

22、ion (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 least 75 % of the member bodies casting a vote. Internation

23、al Standard ISO 8745 was prepared by Technical Committee ISO/TC 2, Fasteners. This second edition cancels and replaces the first edition (ISO 8745:1986), which has been technically revised. Descriptors: Fasteners, steel products, pins (mechanics), grooved pins, specifications, characteristics, dimen

24、sions, designation.ENISO8745:1997 BSI 04-1999 1 1 Scope This International Standard specifies the characteristics of half-length taper grooved pins made of steel or austenitic stainless steel which have three equally spaced grooves impressed longitudinally on their exterior surface, with nominal dia

25、meter, d 1 , from 1,5mm to 25mm inclusive. The displaced material to each side of the grooves forming an expanded diameter, d 2 , which is larger than the nominal diameter d 1will cause a non-positive locking fit when these grooved pins are forced into a drilled hole equal to the nominal diameter d

26、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 are subject to revision, and parties to agree

27、ments based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
