EN 1216:1998 BSI 28 March 2003 3 0 Introduction This European Standard is one of a series of European Sta
27、ndards dedicated to heat exchangers. 1 Scope This European Standard applies to forced circulation air-cooling or air-heating coils operating: a) with an evaporating or condensing refrigerant; b) with a cooling or heating fluid; c) without fans. Operation with steam is not part of the standard. This
28、standard specifies uniform methods of testing under non-frosting conditions conducted on test samples to test and ascertain the following: product identification; the capacity; air side pressure drop; fluid side pressure drop. at standard conditions, unless otherwise stated by the user. It is not th
29、e purpose of this standard to specify the types of test used for production or field testing. 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 t
30、he 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 publication referred to applies: EN 45001
