EN 13611:2019, Clause 1 applies with the following modification and addition:

Modification:

The 1st paragraph of EN 13611:2019, Clause 1 is replaced by:

This document specifies the safety, design, construction, and performance requirements and testing for pressure regulators and pneumatic gas/air ratio pressure regulators (zero pressure regulators are included as a special type of pneumatic gas/air ratio pressure regulators) for burners and appliances burning one or more gaseous fuels, hereafter referred to as ´pressure regulators´.

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.
