Safety and control devices for gas burners and gas burning appliances - Part 1: Pressure regulators for inlet pressures up to and including 50 kPa

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.

Sprememba:
Prvi odstavek točke 1 standarda EN 13611:2019 nadomešča naslednje besedilo:
Ta dokument določa zahteve za varnost, načrtovanje, izdelavo in delovanje ter preskušanje regulatorjev tlaka in regulatorje tlaka z nadzorom razmerja med pnevmatskim plinom/zrakom (regulatorji z ničelnim tlakom so
vključeni kot posebna vrsta regulatorja tlaka z nadzorom razmerja med pnevmatskim plinom/zrakom) za gorilnike in aparate,
ki uporabljajo enega ali več plinastih goriv (v nadaljnjem besedilu »regulatorji tlaka«).
Ta dokument se uporablja za regulatorje tlaka z določenim največjim vstopnim tlakom do
vključno 50 kPa in nazivno velikostjo priključkov do vključno DN 250.
Dodatek:
Ta dokument se uporablja za:
– regulatorje tlaka, ki uporabljajo pomožno energijo;
– regulatorje tlaka z nadzorom razmerja med pnevmatskim plinom/zrakom, ki delujejo na podlagi nadzora izstopnega tlaka plina
kot odziv na signal zračnega tlaka, signal diferenčnega zračnega tlaka in/ali signal tlaka peči
(regulatorji z ničelnim tlakom so vključeni kot posebna vrsta regulatorja tlaka z nadzorom razmerja med pnevmatskim
plinom/zrakom);
– regulatorje tlaka z nadzorom razmerja med plinom/zrakom, ki spremenijo izstopni zračni tlak kot odziv na signal
plinskega tlaka ali signal diferenčnega plinskega tlaka.
Ta dokument se ne uporablja za:
– regulatorje tlaka, priključene neposredno na omrežje za distribucijo plina ali vsebnik, ki ohranja
tlak pri običajni distribuciji;
– regulatorje tlaka, namenjene za plinske aparate, ki jih je treba namestiti na odprtem in so izpostavljeni
okolju;
– mehansko povezane naprave z nadzorom razmerja med plinom/zrakom;
– elektronske naprave z nadzorom razmerja med plinom/zrakom (EN 12067-2:2022).
Četrti odstavek točke 1 standarda EN 13611:2019 je odstranjen.
