This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2013, and conflicting national standards shall be with
22、drawn at the latest by April 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document, together with EN 16297-2:2012, super

BS EN 16297-1:2012EN 16297-1:2012 (E) 4 Introduction This European Standard has been prepared under mandate M/469 EN of 22 June 2010 given to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to Requirements of the EU Directive 2005/32/EC o
28、f 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 efficiency index of circulators. The document comprises standalone circulators and circulators integrated in products. NOTE
29、 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 to operate independently from the product and should be tested and calculated in accordance with EN 16297-2. Circulator i
30、ntegrated 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 can be used as guidance for deciding when EN 16297-3 applies. A circulator is considered to be operated dependently if it c
31、arries 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 used inside a product Housings designed for use inside products e.g. with clip connections, with back panel connection or
32、 plate heat exchanger connections. Housings integrating electrically or thermally driven valve functions Control Designed to be speed controlled by the product Circulators with product specific control signal interfaces Safety measures Designed with safety features not suitable for stand alone opera
33、tion Product takes over safety features (ISO IP classes) Circulator is a defined part of product approval or product CE marking Circulator is part of the component list of product approval or product CE marking BS EN 16297-1:2012EN 16297-1:2012 (E) 5 1 Scope This European Standard specifies general
34、performance requirements and general requirements and procedures for testing and calculation of the energy efficiency index (EEI) for glandless circulators having a rated hydraulic output power of between 1 W and 2500 W designed for use in heating systems or cooling distribution systems. All known h
35、azards which are likely to occur at normal installation and operation are covered by the European Standards EN 809 and EN 60335-2-51. As regards safety for electro-technical parts of circulators, EN 60335-2-51 applies. 2 Normative references The following documents, in whole or in part, are normativ
36、ely referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1151-2:2006 Pumps Rotodynamic pumps Circulation pumps having a
