Safety and control devices for gas burners and gas burning appliances - Part 3: Pressure and/or flow rate regulators for inlet pressures up to and including 500 kPa, electronic types; German version EN 88-3:2022
Sicherheits- und Regeleinrichtungen für Gasbrenner und Gasgeräte - Teil 3: Druck- und/oder Durchflussregler für Eingangsdrücke bis einschließlich 500 kPa, elektronische Ausführung; Deutsche Fassung EN 88-3:2022
Overview
This standard specifies the safety, design, construction, and performance requirements and testing for electronic pressure and/or flow rate regulators for burners and appliances burning one or more gaseous fuels, hereafter referred to as "regulators". This document is applicable to regulators with declared maximum inlet pressures up to and including 500 kPa and of nominal connection sizes up to and including DN 250. This document is applicable to: - regulators which use auxiliary energy; - regulators, which function by controlling a gas outlet pressure or a gas flow rate; - regulators with a modular structure specified as a unit; - regulators intended for gas appliances to be installed indoor or in the open air and exposed to the environment. This document is not applicable to: - regulators connected directly to a gas distribution network or to a container that maintains a standard distribution pressure. This standard (EN 88-3:2022) has been prepared by Technical Committee CEN/TC 58 "Safety and control devices for burners and appliances burning gaseous or liquid fuels", the secretariat of which is held by BSI (United Kingdom). The responsible German standardization committee is Joint Working Committee NA 041-03-10 GA "Gemeinschaftsarbeitsausschuss NHRS/NAA/NAGas: Sicherheits- und Regeleinrichtungen für wärmeerzeugende Geräte und Anlagen sowie für die Gasversorgung (SpA CEN/TC 58, WG 11, WG 13, WG 15 und ISO/TC 161, WG 3, WG 4, WG 5)" ("Joint working committee NHRS/NAA/NAGas: Safety and control devices for heating appliances and heat generating systems and for the gas distribution (SpA CEN/TC 58, WG 11, WG 13, WG 15 and ISO/TC 161, WG 3, WG 4, WG 5)") at DIN Standards Committee Heating and Ventilation Technology and their Safety (NHRS).
