BS EN 15202:2012EN 15202:2012 (E) 4 Introduction The primary objective of this European Standard is to ensure the safe connection of LPG c

18、ylinder valves to their connectors. This European Standard is the fundamental source for identifying the essential manufacturing dimensions of the LPG cylinder valve connections used in Europe. prEN 16129 is the fundamental source for identifying the essential manufacturing dimensions of other conne

19、ctor types not used with LPG cylinder valves. This European Standard identifies the existing cylinder valves and the connectors that are currently in use with LPG. It is the intention that only connections which are identified in this standard should be used with LPG cylinder valves. This European S

20、tandard lists potentially unsafe connections where it may be possible to connect together, but which, when connected, may not be sound or secure in some operating conditions or orientations. This standard specifies a marking system that is intended to ensure that only valves and connecters that are

21、marked with the same connector type number are used in combination. BS EN 15202:2012EN 15202:2012 (E) 5 1 Scope This European Standard specifies basic connection dimensions of LPG cylinder valves (manufactured in accordance with EN ISO 14245 and EN ISO 15995) and connectors (including pressure regul

22、ators) to enable them to be safely connected together. NOTE 1 Figure 1 (type G.1) to Figure 19 (type G.33) give the types of threaded outlet connections. NOTE 2 Figure 20 (type G.50) to Figure 34 (type G.66) give the types of non-threaded outlet connections. This European Standard lists potentially

23、unsafe connections where it may be possible to connect together, but which, when connected, may not be sound or secure in some operating conditions or orientations. This European Standard specifies a marking system that is intended to ensure that only valves and connecters that are marked with the s

24、ame connector type number are used in combination. This European Standard also recommends tightening torques for the attachment of screwed metal-to-metal connections. Quality assurance systems, production testing and particularly certificates of conformity are not covered in this standard. This Euro

25、pean Standard excludes connections for automotive vehicles covered by UN/ECE Regulation No. 67 Part 1 and EN 13760. This European Standard excludes connections for gas cartridges covered by EN 417. 2 Normative references The following documents, in whole or in part, are normatively referenced in thi
