This document specifies safety, constructional, performance, testing and documentation requirements of gas safety shut-off devices (SSDs).
This document is applicable to SSDs with operating pressures greater than 500 kPa (5 bar1) up to 10 MPa (100 bar) of nominal connection sizes up to and including DN 400 for use with fuel gases such as natural gas, manufactured gas, biomethane or liquefied petroleum gas (LPG) in commercial industrial installations, including fuel gas infrastructures.
This document is applicable to SSDs for an operating temperature range from −20 °C to +60 °C;
This document is applicable to:
— test methods which are intended for product type tests, routine tests and batch surveillance tests;
— SSDs which use the pipeline gas as a source of control energy unassisted by any external power source;
— SSDs integrating on the same body a second SSD, conforming to the requirements in this document;
— SSDs integrating a gas pressure regulator conforming to ISO 23555‑2;
— SSDs incorporating a creep (venting) relief device and/or a vent limiter conforming to the requirements in this document;
