DIN EN 15420:2011-03

This standard has been prepared to deal with aspects related to: - safety; - rational use of energy; - fitness for purpose. Other types of boilers are dealt with in separate standards. This standard covers only type testing. Matters related to quality assurance systems, tests during production and to certificates of conformity to auxiliary devices are not dealt with in this standard. It is impractical to use the full range of test gases to EN 437 for type testing since their availability for inputs over 300 kW may present problems for test houses and manufacturers. Informative Annex O gives guidance on the use of gases for tests in order to still ensure conformity with the requirements of EC Directive 90/396/EEC "Gas Appliances Directive". The Committee responsible for this standard is NA 032-03-01 AA "Häusliche, gewerbliche und industrielle Gasanwendung" ("Domestic, commercial and industrial gas use") at DIN.
