22、 Standard, ISO 7005-1, Steel flanges. In taking this decision, CEN/TC 74, agreed that this standard would differ significantly from the ISO standard in respect of the following: a) Whereas ISO 7005-1 included in its scope both the original DIN based flanges and also the original ANSI/ASME based flan

CEN/TC 74 has produced a separate series of standards, EN 1092 Parts 1, 2, 3 and 4, dealing with the DIN based flanges in PN designations; b) In this standard, the flanges are Class designated (not PN designated as in the I
24、SO standard) and those dimensions taken from ASME B16.5 are hard metricated. Consequently, whilst the mating dimensions, the flange and facing types and designations are compatible with those given in ISO 7005-1, it is important to take account of the following differences which exist in EN 1759-1:
