This document (EN 16297-1:2012) has been prepared by Technical Committee CEN/TC 197 “Pumps” (Secretariat: AFNOR, France). The responsible German body involved
7、 in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-11-01 AA Kreiselpumpen of Section Kreiselpumpen. Representatives of manufacturers and users of glandless circulators, and of the employers liability insurance associations
8、contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC in conjunction with Directive 2009/125/EC and Commission Regulation (EC) No 641/2009, and which apply to machines that are eith
9、er first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of these directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufa
10、cturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same n
11、umber. For the International Standards which have not been published as DIN ISO Standards with the same number, there are no national standards available. Amendments This standard differs from DIN EN 1151-1:2006-11 and DIN EN 1151-1 Corrigendum 1:2008-06 as follows: a) the scope now includes electri
12、cally controlled pumps; b) the standard has been subdivided; c) the procedure for calculating the energy efficiency index (EEI) of standalone circulators has been included to meet the requirements of the Ecodesign Directive.

32、 and the European Free Trade Association to provide a means of conforming to Requirements of the EU Directive 2005/32/EC of 6 July 2005 and Commission Regulation (EC) 641/2009 of 22 July 2009 by describing procedures for measurement and calculation of hydraulic power, power consumption, and energy e
33、fficiency index of circulators. The document comprises standalone circulators and circulators integrated in products. NOTE For the purpose of this document, the term “product“ is used in the sense of an appliance that generates and/or transfers heat. Standalone circulator means a circulator designed
34、 to operate independently from the product and should be tested and calculated in accordance with EN 16297-2. Circulator integrated in a product means a circulator designed to operate dependently of the products and should be tested and calculated in accordance with EN 16297-3. The following table c
35、an be used as guidance for deciding when EN 16297-3 applies. A circulator is considered to be operated dependently if it carries at least one of the design details listed in Table 1. Table 1 When EN 16297-3 applies Design Details Examples (non exhaustive list) Pump housing Designed to be mounted and
36、 used inside a product Housings designed for use inside products e.g. with clip connections, with back panel connection or plate heat exchanger connections.
