VET-158-1-2004 Standard

VET-158-1-2004 Standard

The VED-158-1-2004 secondary standard is designed to reproduce and store water dew (frost) point and hydrocarbon condensation temperatures. This data can then be transferred to lower level reference hygrometers and operational measuring devices, and used for R&D in the field of metrological support of hygrometry.
This standard is included in the national verification scheme: "GSI. National verification scheme for gas relative humidity measurement devices." The GOST 8.547-2009 registration number for the VET-158-1-2004 Standard in the Federal Information Fund Register is 3.2.ZBУ.0698.2014.

Signature features:

The dew point/condensation temperature for water and hydrocarbons, respectively, is reproduced by means of the phase equilibrium method at pressures from near atmospheric to 10 MPa.
The water dew point and hydrocarbon condensation temperatures are reproduced at the same time
