This document is applicable to pressure regulators with declared maximum inlet pressures up to and including 50 kPa and of nominal connection sizes up to and including DN 250. Addition: This document is applicable to: - pressure regulators which use auxiliary energy; - pneumatic gas/air ratio pressure regulators, which function by controlling a gas outlet pressure in response to an air signal pressure, air signal differential pressure, and/or to a furnace pressure signal (zero pressure regulators are included as a special type of pneumatic gas/air ratio pressure regulators); - pneumatic gas/air ratio pressure regulators, which change an air outlet pressure in response to a gas signal pressure or a gas signal differential pressure. This document is not applicable to: - pressure regulators connected directly to a gas distribution network or to a container that maintains a standard distribution pressure; - pressure regulators intended for gas appliances to be installed in the open air and exposed to the environment; - mechanically linked gas/air ratio controls; - electronic gas/air ratio controls (EN 12067-2:2022). The 4th paragraph of EN 13611:2019, Clause 1 is removed.
