It is intended to include this standard in the body of technical rules and standards for
7、 gas issued by the DVGW Deutscher Verein des Gas- und Wasserfaches e.V. (German Technical and Scientific Association for Gas and Water). This document contains specifications giving detail to the essential requirements set out in Annex I of the “Gas Appliances Directive“, Directive 2009/142/EC (see
8、also Annex ZA). Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance (“presumption of conformity”) with the requirements of Annex I of Directive 2009/142/EC.

39、lectric flame supervision devices, energized by a thermocouple intended for use with gas burners, gas appliances and similar use, hereafter referred to as “controls“. This European Standard is applicable to controls with declared maximum inlet pressures up to and including 500 kPa (5 bar) of nominal
40、 connection sizes up to and including DN 50 for use with one or more fuel gases in accordance with EN 437. This European Standard is not applicable to: a) the thermocouple; b) controls which use auxiliary energy (e.g. electrical energy supplied externally). 2 Normative references The following refer

43、e flame effect produces an electromotive force (e.m.f.) 3.102 flame supervision device control which, in response to the e.m.f. produced by the thermocouple, maintains the gas way to the main burner or the main burner and the pilot burner open and which shuts off the gas way to the main burner at le
44、ast, after extinction of the supervised flame NOTE For further reference see Figure AA.1 and Figure AA.2. 3.103 ignition interlock part which prevents the igniter from operating as long as the main gas way is open 3.104 re-start interlock mechanism which prevents the re-opening of the gas way to the
45、 main burner or to the main burner and the pilot burner until the armature plate has separated from the magnetic element NOTE For further reference see Figure AA.1 and Figure AA.2.
