Verification diagram:
- “State verification scheme for measuring instruments of excess pressure up to 4000 MPa”, approved by the Order of the Federal Agency for Technical Regulation and Metrology dated 2026 No.
Scope of application:
Oil and gas product metering units, aerospace, electronics, defense and other branches of national industry.
Results of applying the standard:
The need for high-precision measurements of excess pressures, testing of new types of pressure measuring instruments has been met, and solutions to priority areas of development in science, technology, and engineering in the Russian Federation have been provided at a higher level.
The total number of measuring instruments traceable to ГЭТ 23-2026:
Several million measuring instruments, including hundreds of thousands of measuring instruments used as standards
Ensuring the uniformity of measurements, participation in the CIPM MRA program:
