Traceability in the field of hardness for GB BCS accredited laboratories will be transfered to IMGC, IT. To support the proposed role of IMGC as the EUROMET centre for hardness measurement a scientific and technical collaboration will be established between NPL and IMGC. To ensure a smooth transition to IMGC of traceability, equipment such as indenters, reading blocks and calibrated hardness blocks will be transfered from NPL to IMGC. This will be supported by discussions between the two Laboratories on primary hardness calibration procedures to ensure compatability with BS specifications is maintained. The Laboratories will collaborate on the future development in hardness standards.
