2、opy, (c) BSI BS EN 15316-4-2:2008 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 29 August 2008 BSI 2008 ISBN 978 0 580 59468 7 National foreword This British Standard is the UK implementation of EN 15316-4-2:2008. The UK participation in it
3、s preparation was entrusted to Technical Committee RHE/24, Central heating installations. A list of organizations represented on this committee can be obtained on request to its secretary. BSI, as the UK member of CEN, is obliged to publish EN 15316-4-2:2008 as a British Standard. However, attention
4、 is drawn to the fact that during the development of this European Standard, the UK voted against its approval as a European Standard The UK voted against this standard on the grounds that it was considered disproportionate to the essential requirements of the EU Energy Performance of Buildings Dire
5、ctive (2002/91/EC), which it supports. In the opinion of the UK committee, EN 15316-4-2:2008 is regarded as unsuitable for existing buildings where the data required are unlikely to be available. This publication does not purport to include all the necessary provisions of a contract. Users are respo
6、nsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations.

9、pumpensysteme This European Standard was approved by CEN on 15 May 2008. CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliogra

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a
11、 CEN member into its own language and notified to the CEN Management Centre has the same status as the official versions. CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland
