6 Marking
Applies differential pressure (type) measuring instruments (instrument) with a shut-off device (manifold) directly bolted on to them. It specifies mating dimensions and tolerances, threads, bolts, and gaskets for a maximum allowable working pressure of 41,3 MPa (413 bar) at 38 deg C. This Standard does not apply to assemblies that provide additional sealing elements (adapters) between the instrument and the manifold. This Standard is only valid for instrument and manifold flanges manufactured from a metallic material with yield strength equal to , or larger than, 190 N/mm2
