1、DEUTSCHE NORM November 1999 Screw threads General plan I ICs 21.040.01 Gewinde - bersicht Supersedes January 1988 edition. In keeping with current practice in standards published by the International Organization for Standardization (ISO), a comma has been used throughout as the decimal marker. Fore
2、word This standard has been prepared by Technical Committee Gewinde of the Normenausschuss Technische Grundlagen (Fundamentals in Technology Standards Committee). Amendments This standard differs from the January 1988 edition as follows: a) Table 1 has been amended taking into acount the specificati
3、ons of DIN 13-52, DIN 8141-1, DIN EN 144-1, and DIN IS0 6698. b) Table 1 now also includes DIN 55525 buttress threads; DIN 4930 taper knuckle threads and DIN 4941 tapered drill pipe threads have been dropped. c) Table2 has been extended to include IS0 metric screw threads complying with ISO965-4 and
4、 IS0 965-5. Previo us edit ions DIN 202: 1923-02, 1924, 1926-04, 1938-07, 1974-08, 1981-12, 1988-01 1 Scope This standard gives an overview of screw threads used either for general purposes or in special applications, threads complying with DIN Standards being given in table 1 and those complying wi
5、th IS0 Standards in table 2. 2 Normative references This standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the titles of the publications are listed below. For dated references, su
6、bsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies. See tables 1 and 2. 3 Designation The thread designation is generally to c
7、omprise the symbol denoting the type of thread and the value of the nominal diameter or nominal size, followed, where required, by the value of the pitch or number of threads, tolerance, number of starts, taper and whether the thread is a left-hand thread. In the case of a number of screw threads co
8、nforming to DIN Standards, the designation is preceded by the DIN number. It should be noted that, when using tables 1 and 2, only the latest edition of each standard referred to shall apply.
