The work of preparing International Standards is normally carried out through ISO techni

19、cal 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 ISO, also take part in the work. ISO collaborates closely w

20、ith 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 International Standard requires approval by at least 75 % of

21、 the member bodies casting a vote. International Standard ISO 5261 was prepared by Technical Committee ISO/TC 10, Technical drawings, product definition and related documentation, Subcommittee SC 6, Mechanical engineering documentation.

24、SO 5261:1999 BSI 15 September 2002 1 1 Scope This International Standard specifies rules complementary to ISO 128 1)and ISO 129 for the simplified representation of bars and profile sections in assembly and detail drawings concerning, among others: structural metal work consisting of plates and shee

25、ts, profile sections and compound elements (including bridges, frameworks, pilings, etc.); lifting and transport appliances; storage tanks and pressure vessels; lifts, moving stairways and conveyor belts. 2 Normative references The following standards contain provisions which, through reference in t

26、his 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 encouraged to investigate the possibility of applying the most rece

27、nt editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

29、ist of their relevant ISO designation followed, if necessary, by the cutting length, separated by a hyphen. This designation may also be used when filling in an item list (see ISO 7573). EXAMPLE The simplified representation of an equal leg angle profile in accordance with ISO 657-1, measuring 50 mm

30、 50 mm 4 mm and having a cutting length of 1 000 mm shall consist of the following ISO designation: Angle profile ISO 657-1 50 50 4 1 000 If there is no designation specified in an International Standard or other relevant standard, the designation shall be composed of the graphical symbol followed b

In this case, the values of the distances between the reference points of the centroidal lines shall be indicated directly on the represented elements (see Figure 4).
