4、 validity This standard takes effect on 1 June 2009. DIN EN 14710-2:2008-06 may be used in parallel until 28 December 2009. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 192 “Fire service equipment” (Secretariat: BSI, Unit
5、ed Kingdom), Working Group WG 2 “Fire-fighting pumps” (Secretariat: DIN, Germany). This document includes Amendment A2:2008. The responsible German body involved in its preparation was the Normenausschuss Feuerwehrwesen (Firefighting and Fire Protection Standards Committee), Technical Committee NA 0
6、31-04-05 AA Feuerlschpumpen. For further information about the Normenausschuss Feuerwehrwesen (FNFW), please refer to www.fnfw.din.de. Amendment A2:2008 to EN 14710-2:2005 became necessary for the following reasons: Until now, fire-fighting centrifugal pumps conforming to DIN 14710 have been limited
7、 to a nominal delivery rate of not more than 6 000 l/min. However, in view of the rising demand on the part of customers for pumps with higher delivery rates (i.e. for pumps that have a better performance capability while satisying all the requirements and tests specified in DIN 14710), CEN/TC 192 h
8、as decided to increase the nominal delivery rate of fire-fighting centrifugal pumps conforming to DIN EN 14710 to a maximum of 10 000 l/min. Amendment, A1:2008, which was first included in the consolidated September 2008 edition of this standard, was necessitated by the revision of the Machinery Dir
9、ective 98/37/EC and its replacement through 2006/42/EC, effective from 29 December 2009, requiring modifications to the European Standards cited under that Directive in the Official Journal of the European Communities. If these modifications had not been made, then an Annex Z would have been added t
10、o the relevant standard stating that the standard does NOT comply with the relevant essential requirements of Directive 2006/42/EC. The standard would have then been deleted from the Official Journal and would have no longer been deemed a harmonized standard. To maintain its status as a harmonized s
11、tandard, EN 14710-2:2005 has been carefully reviewed and compared with the revised Machinery Directive 2006/42/EC; it has been determined that the standard complies with the requirements of 2006/42/EC. Therefore, CEN/TC 192 decided in June 2007 to use the “simple amendment” (type 1) procedure which
12、does not involve any technical modifications, but only a few minor editorial changes (e.g. updating the Foreword) and the addition of a new Annex ZB. Amendment A1:2008, in conjunction with the previous edition EN 14710-2:2005 thus contains specifications meeting the essential requirements set out in
13、 Annex I of the “Machinery Directive”, Directive 98/37/EC (valid until 28 December 2009), and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to machines that are either first placed on the market or commissioned within the EEA. This s
14、tandard serves to facilitate proof of compliance with the essential requirements of the directives. 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 with the requireme
15、nts of the Machinery Directive (“presumption of conformity”) A revision of Part 1 of EN 14710 (EN 14710-1:2005) was also necessary for the same reasons. This European Standard is to be applied in conjunction with Part 1 of EN 14710 Classification, general and safety requirements. DIN EN 14710-2:2009
