19、est by December 2004. This document will supersede EN 215-1:1987 and HD 1215-2:1988. This European Standard constitutes the merging of 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
20、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 form the basis of a possible certification scheme for radiator valves. EN 215-1:1987 was first accepted by CEN on 1986-10-28, published
21、in July 1987, and a Corrigendum EN 215:1987/AC 1:1987 was published in November 1987. This European Standard incorporates the corrigendum, 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
22、 1987-08-13, published in September 1988, and a Corrigendum HD 1215-2:1988/AC1:1989 was published in March 1989. This European Standard incorporates 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 Cer
