5、 this standard is 2015-10-01. National foreword This standard includes safety requirements. This document (EN 15502-1:2012+A1:2015) has been prepared by Technical Committee CEN/TC 109 “Central heating boilers using gaseous fuels” (Secretariat: NEN, Netherlands). The responsible German body involved

6、in its preparation was the DIN-Normenausschuss Gastechnik (DIN Standards Committee Gas Technology), Working Committee NA 032-03-01 AA Husliche, gewerbliche und industrielle Gasanwendung. This standard has been developed with the consensus of the DVGW Deutscher Verein des Gas- und Wasserfaches e.V. (

7、German Technical and Scientific Association for Gas and Water). It is intended to include this standard in the body of technical rules and standards for gas issued by the DVGW Deutscher Verein des Gas- und Wasserfaches e.V. (German Technical and Scientific Association for Gas and Water). Amendments

8、This standard differs from DIN EN 15502-1:2012-10 as follows: a) The following clauses have been revised with regard to ecodesign and energy labelling: Clause 8 “Operational requirements”; Clause 9 “Useful efficiencies”; Clause 10 “Electric auxiliary energy”. b) The following amendments have been ma
