This European Standard specifies general terms and calculations used in deter- mining performance of heat exchangers including related theory and general test procedure. This European Standard applies to heat exchangers classified according to the general arrangement of heat transfer specified by heat transfersurface types of 4.1 and 4.2 of prEN 247:1996. This European standard applies when referenced by the various branch applicationstandards. The specific application European standards shall be the prime reference documents.
