15、 PN 40. b) For PN 10 instrument nozzles, the d4 value for a size DN1 of 25 was corrected and branch sizes (DN2) 40 and 50 have been dropped. c) Designations for steel and cast iron have been updated. d) Some new steel grades have been introduced. e) The speci?cations have been harmonized with DIN EN

16、 1092-1. f) The standard has been editorially revised. Previous editions DIN 2848: 1976-07, 1993-12; DIN 2848-10: 1982-01; DIN 2848-11: 1982- 01; DIN 2848-12: 1982-01.
