Gas pressure regulators for inlet pressures up to 100 bar

This document specifies constructional, functional, testing and marking requirements, sizing and documentation of gas pressure regulators used in the pressure regulating stations in accordance with EN 12186 or EN 12279: - 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 in accordance with EN 437 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 regulating stations complying with EN 12186 or EN 12279, Annex ZA lists all applicable Essential Requirements except the external corrosion resistance in case of environmental conditions where corrosion is likely to occur. This document considers the following classes/types of regulators: - class 1: operating temperature range from 10 °C to 60 °C; - class 2: operating temperature range from 20 °C to 60 °C; - type IS: (integral
