This document specifies safety, constructional, performance, testing and documentation requirements for gas pressure regulators for use in gas transmission and distribution installations (hereafter referred to as regulators).<\/p>\n
This document is applicable to regulators with operating pressures greater than 500\u00a0kPa and up to and including 10\u00a0MPa (100\u00a0bar) and nominal diameters up to DN 400 for use with fuel gases as natural gas, manufactured gas, biomethane or liquefied petroleum gas (LPG).<\/p>\n
This document is applicable to:<\/p>\n
\u2014\u00a0\u00a0\u00a0 test methods which are intended for product type test, routine tests and product surveillance tests;<\/p>\n
\u2014\u00a0\u00a0\u00a0 regulators which use the pipeline gas as a source of control energy unassisted by any external power source;<\/p>\n
\u2014\u00a0\u00a0\u00a0 regulators integrating on the same body a second regulator, used as monitor, complying with the requirements in this document;<\/p>\n
\u2014\u00a0\u00a0\u00a0 regulators integrating a safety shut off device (SSD) according to ISO\u00a023555-3;<\/p>\n
\u2014\u00a0\u00a0\u00a0 regulators incorporating a creep (venting) relief device and\/or a vent limiter complying with the requirements in this document.<\/p>\n
This document does not apply to:<\/p>\n
