Amendments This standard differs from DIN EN 215:2004-09 as follows: Amendment A1:2006 has been incorporated. a) The standard now also applies to two-port thermostatic val

6、ves with or without a pre-setting facility. b) Subclause 5.3.4 “Change of the flow rate by means of the protection cap” and subclause 6.4.1.6 “Change of the flow rate by means of the protection cap” have been deleted. c) The hysteresis at nominal flow rate, differential pressure influence, water tem

7、perature influence and response time are now to be included in the “Technical information to be published by the manufacturer in the manufacturers instructions for installation and operation” (clause 7). d) When testing operating characteristics, the value given by the manufacturer for the hysteresi

8、s at nominal flow rate shall not be exceeded by more than 0,2 K, that for the differential pressure influence shall not be exceeded by more than 0,3 K, that for the water temperature influence shall not be exceeded by more than 0,3 K and that for the response time shall not be exceeded by more than

19、ndard, either by publication of an identical text or by endorsement, at the latest by December 2004, and conflicting national standards shall be withdrawn at the latest by December 2004. This document will supersede EN 215-1:1987 and HD 1215-2:1988. This European Standard constitutes the merging of

20、EN 215-1:1987 and HD 1215-2:1988, according to Resolution BT 80/1998. The merging has been provided such that HD 1215:1988 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 requirem

21、ents and a test procedure to form the basis of a possible certification scheme for radiator valves. EN 2151:1987 was first accepted by CEN on 1986-10-28, published in July 1987, and a Corrigendum EN 215:1987/AC 1:1987 was published in November 1987. This European Standard incorporates the corrigendu

22、m, and it will thus supersede EN 215-1:1987 and EN 215-1:1987/AC 1:1987. This European Standard further includes HD 1215-2:1988, which was first accepted by CEN on 1987-08-13, published in September 1988, and a Corrigendum HD 1215-2:1988/AC1:1989 was published in March 1989. This European Standard i

23、ncorporates the corrigendum, and will supersede HD 1215-2:1988 and HD 1215-2:1988/AC1:1989. This European Standard can be used as a reference for a CEN/CENELEC Certification Mark System on radiator valves. Annex A is normative; Annexes B and C are informative. This document includes a Bibliography.

EN 215:2004 + A1:2006 (E)4 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 thermostat

29、ic 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

30、 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

31、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 thi

32、s 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).
