This document will supersede EN 215-11987 and HD 1215-21988. This European Standard constitutes the merging of EN 215-11987 and HD 1215-21988, according to Resolution BT 80/1998. The merging has been provided such that HD 12151988 has been included into prEN 215 mainly as a normative annex. The work on radiator valves started in September 1982 in CEN/TC 105 with the aim of drafting a standard for requirements and a test procedure to the basis of a possible certification scheme for radiator valves. EN 215- 11987 was first accepted by CEN on 1986-10-28, published in July 1987, and a Corrigendum EN 2151987/AC 11987 was published in November 1987. This European Standard incorporates the corrigendum, and it will thus supersede EN 215-11987 and EN 215- 11987/ AC 11987. This European Standard further includes HD 1215-21988, which was first accepted by CEN on 1987-08-13, published in September 1988, and a Corrigendum HD 1215-21988/AC11989 was published in March 1989. This European Standard incorporates the corrigendum, and will supersede HD 1215-21988 and HD 1215- 21988/AC11989. This European Standard can be used as a reference for a CEN/CENELEC Certification Mark System on radiator valves. Annex A is normative. Annex B is inative. This document includes a Bibliography. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

This standard applies to two port thermostatic 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. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies including amendments. EN 1982 Copper and copper alloys - Ingots and castings.
