21、s (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 represented on that committee. International organizations,
22、 governmental and nongovernmental, 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 Standards adopted by the technical committees are circulated t
23、o the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 58451 was prepared by Technical Committee ISOflC 1 O, Technical drawings, product definition and related documen- tation, Subcom
24、mittee SC 6, Mechanical engineering documentation. 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 Technical drawings - Simplified representation of the assembly

II STD-BSI BS EN IS0 5845-1-ENCL L?97 1111 4LZLibS3 07b393 bB5 = EN IS0 5845-1:1999 Introduction IS0 5845
26、 has been devised to provide a universal means of communi- cation among the various parties involved in the design and manufacture, 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 mu
27、st meet requirements for microcopying and reproduction: a) conventional drawing of fasteners (according to IS0 128); this 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
28、; this method is best suited to drawings con- taining a large number of fasteners (see clauses 4 and 5). Requirements within 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 a
29、erospace equipment. Both are recommended for application to other fields as well. . 111 STD-FIS1 BS EN IS0 SAi5-l-ENGL 3777 Ib2qbb7 U77b374 511 EN IS0 5845-1:1999 Technical drawings - Simplified representation of the assembly of parts with fasteners - Part I: General principles 1 Scope This part of
