European foreword
This document (prEN 215:2017) has been prepared by Technical Committee CEN/TC 130 “Space
heating appliances without integral heat sources”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 215:2004.
This European Standard can be used as a reference for a CEN/CENELEC Certification Mark System on
radiator valves.
1 Scope
This European Standard specifies definitions, requirements and test methods for thermostatic radiator
valves (referred to hereafter as thermostatic valves).
This standard applies to two port thermostatic valves with or without pre-setting facility and
thermostatic integrated valves with or without pre-setting facility for fitting to radiators in wet central
heating installations up to a water temperature of 120 °C and a nominal pressure of PN 10.
This standard further specifies the dimensions, the materials and the connection details of four series of
straight and angle pattern thermostatic radiator valves of nominal pressure ≤ PN 10.
This standard can be used as reference in a CEN/CENELEC Certification Mark System on thermostatic
radiator valves.
