KS C IEC 61518:2014 Mating dimensions between differential pressure (type) measuring instruments and flanged-on shut-off devices up to 413 bar (41.3 MPa)
This standard is applicable to differential pressure (type) measuring instruments (instruments) having direct screwed shut-off devices (manifolds). This standard specifies relative pressure for a maximum permissible operating pressure of 41.3 MPa (413 bar) at 38°C. It specifies the dimensions and tolerances, threads, screws and gaskets. This standard does not apply to assemblies that provide additional sealing elements (adapters) between the instrument and the manifold. The isolation device is mounted on one side of the instrument on which it is possible to mount. All connections must comply with this standard. Elements such as flanged joints may be subject to this standard, or parts of this standard, to increase standardization at the discretion of the supplier and end user. The standard is only valid for instrument and manifold flanges produced from metal with a yield strength of 190 N/mm2 or more.?
