Revision of EURAMET Calibration Guides No. 3 (Calibration of Pressure Balances) and No. 17 (Guidelines on the Calibration of Electromechanical and Mechanical Manometers)
Project Description
EURAMET Calibration Guide No. 3 'Calibration of Pressure Balances', Version 1.0 (03/2011) needs a revision. The minimum amendment concerns appearance of the title page and the references.
Moreover, several new areas of pressure calibrations emerged in last two decades which are not described in any calibration guide. These areas relate to
- low positive gauge pressures
- negative gauge pressures
- calibration of digital piston gauges
It should be analysed whether these specific areas of calibration can be implemented in existing Calibration Guides No. 3 'Calibration of Presssure Balances' and No. 17 'Guidelines on the Calibration of Electromechanical and Mechanical Manometers'.
The work will be performed in the following steps:
- make minimum mandatory revision of Calibration Guide No. 3
- analyse possibility of adopting the new calibration topics into Calibration Guide No. 3 and Calibration Guide No. 17 and, in case of a positive decision
- perform a respective revision of both Calibration Guides

Progress Report 2025-05-19
A formal revision of EURAMET cg-3 "Calibration of Pressure Balances" has been performed.
The main changes concern application pressure range, ambient conditions, handling of instruments, examples involving conventional mass, and reference documents.
Editorial corrections have been done.
The corrected cg-3 Version 2.1 has been approved by EURAMET TC-M and if for approval by BoD. Analysis of cg-3 and cg-17 has been performed to adopt calibration of low positive gauge pressure, negative gauge pressures instruments and digital piston gauges.
Respective revision of both cg's will be continued.
