This document (EN 88-1:2011+A1:2016) has been prepared by Technical Committee CEN/TC 58 “Safety and control devices f
6、or burners and appliances burning gaseous or liquid fuels” (Secretariat: BSI, United Kingdom).

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 Was
8、serfaches e.V. (German Technical and Scientific Association for Gas and Water). This standard contains specifications giving technical detail to the essential requirements set out in Annex I of the “Gas Appliances Directive”, Directive 2009/142/EC (see also Annex ZA). Once this standard is cited in
9、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 the “Gas Appliances Directive”, Directive 2009/142/EC. Directive 2009/142/EC has be
10、en implemented in Germany by the Siebte Verordnung zum Gerte- und Produktsicherheitsgesetz (GPSG) (Seventh Ordinance to the German Equipment and Product Safety Act). Amendments This standard differs from DIN EN 88-1:2011-06 as follows: a) the content of Subclause 7.102.3.1 has been subdivided into S
11、ubclauses 7.102.3.1.1 and 7.102.3.1.2; b) Subclause 7.102.3.2 has been revised; c) the content of Subclause 7.102.3.3 has been subdivided into Subclauses 7.102.3.3.1, 7.102.3.3.2, and 7.102.3.3.3; d) in the new Subclause 7.102.3.3.3, Figure 3 has been added; e) in Subclause 9.2, the former “Figure 3
12、” has been changed to “Figure 4” and the corresponding references in Subclause 9.2, items n) and p), have been changed accordingly.
