ASME B1.20.1:1983, Pipe threads, general purpose (inch) 3 Terms and definitions For the purposes of this document, the terms and definitions of types of valves and components and the terms and definitions given in EN 736-1, EN 736-2 and EN 736-3 apply, together with the following terms and definitions. NOTE The terms maximum allowable pressure, PS, and test pressure, PT, defined in EU Directive 97/23/EC (PED) are equivalent to the terms allowable pressure, ps, and test pressure, pt, defined in EN 736-3:2008. 3.1 loose nut end body end provided with a tailpiece which retains a loose internally threaded nut or ring for connection to the mating component 3.2 union end body end provided with an external thread to which is attached a threaded nut or ring, which retains a tailpiece for connection to the mating component 3.3 NPS alphanumeric designation of size for components of a pipework system, which is used for reference purposes and which comprises, for the purpose of Class designated flanges according to this standard, the letters NPS followed by a dimensionless number which is indirectly related to the physical size of the bore or outside diameter of the end connections NOTE The number following the letters NPS does not represent a measurable value and should not be used for calculation purposes except where specified in the relevant standard.

4.1.3 PN and Class designations The PN and Class designations applicable to valves having flanged, threaded and loose nut/union end body ends shall be as specified in Table 4. NOTE 1 PN 20 and PN 32 are established PN designations for threaded end copper alloy valves and are additional to the list of PN designations given in EN 1333:2006. Valves with capillary or compression ends are not designated by PN or Class. NOTE 2 EN 1254-1:1998, EN 1254-2:1998, EN 1254-3:1998 and EN 1254-5:2007 which give details of the body ends for capillary and compression end valves in this European Standard, do not use the PN designation system given in EN 1333. If PN designations are allocated to capillary or compression end valves, it is the responsibility of the manufacturer to provide information on any pressure and/or temperature limitations in service. SIST EN 12288:2011

4.1.4 Valve series Two series of valves are specified, series A for flanged and threaded end valves and series B for flanged, threaded, capillary, compression and loose nut/union end valves. Series A valves have the shell components constructed from the restricted range of copper-aluminium and copper-tin alloys (see Table A.1) specified in EN 1092-3 and EN 1759-3, and are suitable for the pressure/temperature ratings given in these two flange standards. Additional copper-aluminium and copper-tin alloys are specified in Table A.1 for series A valves and the pressure/temperature ratings for valves in these materials are the same as given in EN 1
