10、ion) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International 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 r

11、epresented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Sta

12、ndards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 Yo of the member bodies casting a vote.

This first edition of IS0 5845-1 is a partial revision of IS0 5261:1981, clause 3 of which has been technically revised. IS0 5845 consists of the following parts, under the general title T

14、echnicai drawings - Simplified representation of the assembly of parts with fasteners: - Part I: General principles - Part 2: Rivets for aerospace equipment Introduction IS0 5845 has been devised to provide a universal means of communi- cation among the various parties involved in the design and man

15、ufacture, in general, as well as the installation of fasteners. The representation of fasteners on technical drawings should conform to one of the following two methods, which must meet requirements for microcopying and reproduction: a) conventional drawing of fasteners (according to IS0 128); this

16、method is particularly suitable for drawings containing a small number of fasteners, or when the use of symbols may not provide complete understanding; b) symbolic representation; this method is best suited to drawings con- taining a large number of fasteners (see clauses 4 and 5). Requirements with

17、in industries vary considerably; in recognition of this fact, IS0 5845 is presented in two parts. Part 1 is mainly devoted to structural metal work. Part 2 is mainly devoted to aerospace equipment. Both are recommended for application to other fields as well. Page 2 IS0 5845-1 : 1995 1 Scope This pa

18、rt of IS0 5845 establishes general principles for the simplified representation of holes, bolts (screws), rivets, etc. on technical drawings. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of IS0 5845. At th

All standards are subject to revision, and parties to agreements based on this part of IS0 5845 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
