Gas pressure safety and control devices for use in gas transmission, distribution and installations for inlet pressures up to and including 10 MPa — Part 2: Gas pressure regulator

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).

This document is applicable to regulators with operating pressures greater than 500 kPa and up to and including 10 MPa (100 bar) and nominal diameters up to DN 400 for use with fuel gases as natural gas, manufactured gas, biomethane or liquefied petroleum gas (LPG).

This document is applicable to:

— test methods which are intended for product type test, routine tests and product surveillance tests;

— regulators which use the pipeline gas as a source of control energy unassisted by any external power source;

— regulators integrating on the same body a second regulator, used as monitor, complying with the requirements in this document;

— regulators integrating a safety shut off device (SSD) according to ISO 23555-3;

— regulators incorporating a creep (venting) relief device and/or a vent limiter complying with the requirements in this document.

This document does not apply to:

— regulators upstream from/on/in domestic gas？consuming appliances which are
