EN 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 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 efficiency 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 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 can 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 used inside a product Housings designed for use inside products e.g. with clip connections, with back panel connection or 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 operation 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
