4、sIn case of doubt, the German-language original shall be considered authoritative.9908.11 DIN EN 545:2011-09 A comma is used as the decimal marker. National foreword This standard has been prepared by Technical Committee CEN/TC 203 “Cast iron pipes, fittings and their joints” (Secretariat: AFNOR, Fr
5、ance). The responsible German body involved in its preparation was the Normenausschuss Rohrleitungen und Dampfkesselanlagen (Piping and Boiler Plant Standards Committee), Working Committee NA 082-00-05 AA Gusseiserne Druckrohre und Formstcke. National Annex NA includes Table NA.1 showing the corresp
6、ondence between the previously used K classes and current pressure classes. This informative Annex is deemed to be necessary because a number of technical rules and standards for gas issued by the DVGW have been based on these K classes and thus a direct comparison can be made. Amendments This stand
7、ard differs from DIN EN 545:2007-02 as follows: a) the scope has been extended; b) pressure classes for all nominal sizes and the resulting component dimensions and characteristics have been included; c) in Subclause 6.6, the mean mass of zinc per unit area has been increased from at least 130 g/m2
8、to at least 200 g/m2; d) installation length and socket depth have been revised to comply with practical requirements; e) the former Annex F “Quality assurance” has been revised and is now included in Clause 9 “Evaluation of conformity”; f) the standard has been brought in line with European directi
9、ves; g) references to European Standards covering external and internal coatings (linings) have been included; h) the standard has been editorially revised. Compared with DIN EN 545:2010-12, the following correction has been made to the German version only and therefore does not affect the English t
10、ext: a) in Table 4, DN 900 to DN 1 400, the value 5,5 has been added for the standardized length Lu. 2 DIN EN 545:2011-09 Previous editions DIN 2614: 1990-02 DIN 2833: 1934-09, 1935-02, 1938x-05 DIN 2834: 1934-09, 1935-02, 1938-05 DIN 2839: 1934-09,1938-05 DIN 2840: 1934-09, 1935-02, 1938-05 DIN 284
