8、 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 represen
9、ted 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 Standards
10、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. International Standard IS0 965-1 was prepared by Technical Committee ISOiTC 1, Screw threads, Subcommit
11、tee SC 2, Tolerances. This third edition cancels and replaces the second edition (IS0 965-3:1980), which has been technically revised. IS0 965 consists of the following parts, under the general title IS0 general purpose metric screw threads - Tolerances - Part 1: Principles and basic data - Part 2:
12、Limits of sizes for general purpose bolt and nut threads - Medium quality - Part 3: Deviations for constructional screw threads - Part 4: Limits of sizes for hot-dip galvanized external threads to mate with internal threads tapped with tolerance position H or G after galvanizing - Part 5: Limits of
13、sizes for internal screw threads to mate with hot-dip galvanized external screw threads with maximum size of tolerance position h before galvanizing Page 2 IS0 965-3 : 1998 1 Scope This part of IS0 965 specifies deviations for pitch and crest diameters for IS0 general purpose metric screw threads (M
14、) conforming to IS0 261 having basic profile according to IS0 68-1. The deviations specified are derived from the fundamental deviations and tolerances specified in IS0 965-1. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisio
15、ns of this part of IS0 965. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of IS0 965 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated belo

18、ntour shall not in any point transgress the basic profile. The tabulated deviation values for the minor diameter of the external thread are calculated on the basis of - truncation and may be used for stress calculations deviation = - + - . For coated threads, the tolerances apply to the paris before
19、 coating, unless otherwise stated. After coating the actual thread profile shall not in any point transgress the maximum material limits for position H or h respectively.
