5、is standard has been prepared by Section B Gewinde of the Normenausschuss Technische Grundlagen (Fundamental Technical Standards Committee). It is an editorially revised edition of DIN 13-26:1983-10, with the normative references updated and the designations modified in form, but not in substance, t
6、o conform with standard terminology (see Amendments). Amendments The following amendments have been made to DIN 13-26:1983-10: a) the title of the standard is now more precise; b) in the German edition of this standard, the following terminology has been modified. The first two terms have also been
7、changed in the English translation: Innengewinde (internal thread) replaces Muttergewinde (nut thread), Auengewinde (external thread) replaces Bolzengewinde (bolt thread), Mindestma (minimum limit of size) replaces Kleinstma, Hchstma (maximum limit of size) replaces Grtma, Toleranzklasse (tolerance
8、class) replaces Toleranzfeld; DIN 13-26:2005-08 3 c) the normative references have been updated; d) the standard has been editorially revised, Previous editions DIN 13-26:1973-02, 1983-10 1 Scope This standard applies for ISO general purpose screw threads with a basic profile as in DIN ISO 68-1. It
9、sets out limits of size for fine pitch threads with nominal thread diameters of 252 mm to 1000 mm, with preferred tolerance classes. 2 Normative references This standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appro
