- 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 regulator),
- 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 European Standard does not cover
- pressure regulators connected directly to 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,

Le présent document spécifie les exigences en termes de sécurité, de construction, de fonctionnement et les essais des régulateurs de pression et des régulateurs pneumatiques de pression du rapport air/gaz (les détendeurs à pression atmosphérique sont inclus à titre de modèle spécial de régulateur pneumatique de pression du rapport air/gaz), destinés à équiper des brûleurs à gaz, des appareils à gaz et des dispositifs analogues, désignés par la suite par « régulateurs de pression ».
Ce document est applicable aux régulateurs de pression supportant des pressions amont maximales déclarées inférieures ou égales à 50 kPa, ayant un diamètre nominal de raccordement jusqu'à DN 250 inclus.
Addition :
Le présent document est applicable :
- aux régulateurs de pression alimentés par une énergie auxiliaire ;
- aux régulateurs pneumatiques de pression du rapport air/gaz, qui fonctionnent en délivrant une pression de gaz en sortie en réponse à un signal de pression d'air, à un signal de pression différentielle d'air et/ou à un signal de pression de combustion (les détendeurs à zéro sont inclus à titre de modèle spécial de régulateurs pneumatiques de pression du rapport air/gaz) ;
- aux régulateurs de pression du rapport air/gaz qui font varier une pression d'air en sortie en fonction d'un signal de pression de gaz ou d'un signal de pression différentielle de gaz.
Le présent document ne couvre pas :
- les régulateurs de pression raccordés directement au réseau de distribution de gaz ou à un récipient qui maintient une pression de distribution normalisée ;
- les régulateurs de pression destinés à des appareils à gaz qui doivent être installés en plein air et exposés aux intempéries ;
