Status: active
Page Count: 34
ICS Code (Valves): 23.060
scope:

This International Standard is applicable to differential pressure (type) measuring instruments (instrument) with a shut-off device (manifold) directly bolted on to them.

This standard specifies mating dimensions and tolerances, threads, bolts, and gaskets for a maximum allowable working pressure of 41,3 MPa (413 bar) at 38 °C.

This standard does not apply to assemblies that provide additional sealing elements (adapters) between the instrument and the manifold.

Where the possibility exists, shut-off devices shall be mounted on either side of the instrument, and all connections shall then meet this standard.

Elements, such as flanged coupling joints, may apply this standard or parts thereof to increase standardization at the discretion of the supplier and the end-user.

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.
