This document (EN 16129:2013) has been prepared by Technical Committee CEN/TC 181 “Dedicated liquefied petroleum gas appliances” (Secretariat: AFNOR, Fra

7、nce). The responsible German body involved in its preparation was the Normenausschuss Gastechnik (Gas Technology Standards Committee), Working Committee NA 032-03-04 AA Flssiggas. This standard has been included in the body of technical rules and standards for gas issued by the DVGW Deutscher Verein

8、 des Gas- und Wasserfaches e.V. (German Technical and Scientific Association for Gas and Water). In this standard, the unit “inch” is used. It should, however, be noted that the Gesetz ber Einheiten im Messwesen (German Law on units in metrology) prohibits the use of the unit “inch” for official and

9、 commercial purposes in Germany. Conversion: 1 inch = 25,4 mm The DIN Standards corresponding to the International Standards referred to in Clause 2 of this standard are as follows: ISO 565 DIN ISO 565 ISO 7005-2 DIN EN 1092-2 Amendments This standard differs from DIN EN 12864:2006-03, DIN EN 12864/

10、A3:2010-08, DIN EN 13785:2010-05 and DIN EN 13786:2010-07 as follows: a) this document merges the standards DIN EN 12864:2006-03, DIN EN 12864/A3:2010-08, DIN EN 13785:2010-05 and DIN EN 13786:2010-07; b) Clause 1 “Scope” has been extended to include adaptors; c) requirements for taking into account

11、 pressure losses of gas installations have been added; d) the two stage safety regulator (over pressure safety device) and the safety diaphragm have been included as regulating devices with safety function; e) drawings of connections described in other standards have been deleted; f) test methods ha
