Implementation of dissemination of unit of mass in emerging mass laboratories

As industrial and technological requirements have increased in recent years, the reliable and effective dissemination of the unit of mass became more critical for laboratories where these techniques are not applied. The EMPIR project “Improvements of the realisation of the mass scale” addressed needs of the emerging mass laboratories. As part of the implementation of the dissemination techniques, two case studies were conducted. Initial case study shows the initial implementation was successful in terms of agreement of the measured values with already known information. Follow-up case study was aimed at the level of achievable uncertainties. Participating laboratories proved their capabilities in the field of dissemination of the unit of mass with uncertainties below requirements for weights of class E1 as defined by document OIML R111:2004.
