This document specifies constructional, functional, testing, marking, sizing and documentation requirements of gas pressure regulators:
— for inlet pressures up to 100 bar and nominal diameters up to DN 400;— for an operating temperature range from - 20 °C to +60 °C,
which operate with fuel gases of the 1st and 2nd family as defined in EN 437:2018 [1], used in the
pressure control stations in accordance with EN 12186 or EN 12279, in transmission and distribution
networks and also in commercial and industrial installations.
"Gas pressure regulators" hereafter will be called "regulators" except in the titles.
For standard regulators when used in pressure control stations complying with EN 12186 or EN 12279,
the Annex ZA lists all applicable essential safety requirements of the European legislation on pressure
equipment except external and internal corrosion resistance for applications in corrosive environment.Cross References:EN ISO 15613:2004EN ISO 12156-1:2018ISO 3419:1981EN ISO 9606-1:2017EN ISO 175:2010EN ISO 15610:2003EN ISO 15612:2018EN ISO 9606-3:1999EN ISO 9712:2012EN ISO 15611:2003EN 60534-2-1:2011EN 1092-4:2002EN 10204:2004EN 60534-2-3:2016EN 14382:2019EN 1759-4:2003EN 13906-2:2013EN 12279:2000/A1:2005EN 1092-1:2018EN 10226-1:2004EN 13906-1:2013EN 1092-3:2003/AC:2004EN 1759-1:2004EN 13906-3:2014EN 60534-3-1:2000EN 13445-4:2014/A1:2016BS EN 14382:2019ISO 1817:2015EN 1092-2:1997EN 1349:2009EN 12516-1:2014+A1:2018ISO 7005-2:1988EN 12516-2:2014EN 10226-2:2005EN 1759-3:2003/AC:2004EN 12516-4:2014+A1:2018EN 12186:2014EN ISO 148-1:2016EN ISO 9606-4:1999EN 549:1994EN ISO 17637:2016EN ISO 15614-1:2017EN ISO 15614-2:2005/AC:2009EN ISO 15609-1:2004EN ISO 14732:2013EN ISO 15607:2003EN ISO 9606-2:2004EN 88-1:2011+A1:2016EN 88-2:2007EN 60534-8-3:2011EN 437:2018EN 60534-3-2:2001EN 12732:2013+A1:2014EN 60534-1:2005ISO 5752EN ISO 14025:2010EN 14717EN ISO 9001:2015EN 61672-1EN ISO 14024:2018EN ISO 6708:1995EN ISO/IEC 17050-1EN 60534-8-3EN ISO 14021:2016ASME PTC 60EN ISO/IEC 17065:2012EN 12627EN 60534-2-1EN ISO/IEC 17025All current amendments available at time of purchase are included with the purchase of this document.
