2、IS0 1 127 : 1992) Supersedes DIN 2462-1 and DIN 2463-1, March 1981 editions, and May 1996 edition. European Standard EN IS0 1127: 1996 has the status of a DIN Standard. A comma is used as the decimal marker. National foreword This standard has been published in accordance with a decision taken by EC
3、ISS/TC 29 to adopt, without alteration, International Standard IS0 1127 as a European Standard. The responsible German body involved in its preparation was the Normenausschu Eisen und Stahl (Steel and Iron Standards Committee). Amendments In comparison with DIN 2462-1 and DIN 2463-1, March 1981 edit
4、ions, the following amendments have been made. a) The specifications for seamless and welded pipes have been combined. b) Tolerances on the pipe length are no longer specified. c) Tolerances on the outside diameter and wall thickness have been changed. d) An outside diameter of 12,7 mm has been incl
5、uded. In comparison with DIN EN IS0 1127, May 1986 edition, a printing error in the German version has been corrected (i.e. no amendment has been made to the English version). Previous editions DIN 2462-1: 1969-03, 1981-03; DIN2463-1: 1969-03, 1981-03; DIN EN IS0 1127: 1996-05. EN comprises 8 pages.
