(German Technical and Scientific Association for Gas and Water). Amendments This standard differs from DIN EN 298:2004-01, DIN EN 2

8、30:2005-10 and DIN EN 298 Corrigendum 1:2006-09as follows: a) the standard has been brought in line with EN 13611:2007+A2:2011; b) the requirements of EN 230 have been incorporated (EN 230 is merged into prEN 298); note: if, due to the reference of EN 13611 the term “gas” will be part of a requireme

9、nt or test, then the term “gas” shall be substituted by the term “fuel” ; c) requirements for flame supervision and the reactions in case of loss of flame have been adapted to the modifications made in EN 267 and EN 676 and optimised for better understanding; d) requirements and tests for “independe

10、nt flame detectors” have been integrated; e) new requirements concerning “common cause” have been added; f) requirements for the new function “remote reset from lock-out” have been added. Compared with DIN EN 298:2012-09 the following correction has been made to the German version only and therefore

11、 does not affect the English text: a) under “Start of application” it has been specified that DIN EN 230:2005-10 may be used in parallel until 2015-05-31.
