Project ComTraForce outcomes
The project concerns the provision of calibration services in the area of mechanical and material testing in the field of force.
In the period from September 1, 2019 to February 28, 2023, the Central Office of Measures participated in the European research project No. 18SIB08 funded by EURAMET under the European Program for Innovation and Research in Metrology (EMPIR) entitled "Comprehensive traceability for force metrology services," with the acronym ComTraForce. The international consortium, coordinated by PTB, involved 13 partners from national metrological institutions (NMIs) and universities.
The main objective of the project was to provide calibration services in the field of mechanical and material testing, using the methods and guidelines necessary to ensure comprehensive measurement traceability in the measurement of static, continuous, and dynamic forces.
The Central Office of Measures participated in the implementation of the tasks of the WP3 work package, the purpose of which was to develop a measurement traceability chain in the measurement of static and continuous forces for metrology services in the field of material testing and other mechanical testing equipment.
The results of GUM's work were published in the following articles:
