5、The DIN 2285 Geometrical product specifications (GPS) GO screw ring gauges for ISO metric screw threads series of standards comprises the following: Part 1: Nominal diameters from 1 mm up to 200 mm for general purposes Part 2: Nominal diameters over 50 mm up to 200 mm for precision engineering Amend
6、ments This standard differs from DIN 2285-1:1989-11 as follows: a) The introductory element “Geometrical product specifications (GPS)” has been added to the title. b) Reference to International Standard ISO 3670:1979 has been deleted as that standard has been withdrawn. c) Terminology has been harmo
7、nized with current standards. d) The standard has been editorially revised.
