SIST EN 13785:2005/kprA1:2008

Regulators with a capacity of up to and including 100 kg/h, having a maximum nominal outlet pressure of up to and including 4 bar, other than those covered by EN 12864 and their associated safety devices for butane, propane or their mixtures

This standard defines the constructional and operational characteristics, the safety requirements and test methods, the marking of regulators having a capacity of less than or equal to 100 kg/h, other than the regulators covered by EN 12864, for butane, propane or their mixtures, in the gaseous phase. Regulators for caravans up to 1,5 kg/h are covered by EN 12864.
NOTE 1 bar = 105 Pa
This European standard also applies to the safety devices which are included within regulators covered by this standard. The characteristics of these devices are given in annexes A and B.

Druckregelgeräte mit einem höchsten Ausgangsdruck bis einschließlich 4 bar und einem Durchfluss bis einschließlich 100 kg/h, die nicht in EN 12864 geregelt sind, für Butan, Propan oder deren Gemische sowie die dazugehörigen Sicherheitseinrichtungen

Détendeurs de débit inférieur ou égal a 100 kg/h, a pression de détente nominale maximale inférieure ou égale a 4 bar, autres que les détendeurs relevant de l'EN 12864, et leurs dispositifs de sécurité associés pour butane, propane ou leurs mélanges

Regulatorji s pretokom do vključno 100 kg/h z največjim imenskim izhodnim tlakom do vključno 4 bar, ki niso vključeni v SIST EN 12864, in s pripadajočimi varnostnimi napravami za butan, propan ali njuni zmesi - Dopolnilo A1
