The CIPM Working Group on Metrology of Materials

摘要

Following international discussion of the traceability issues arising in the measurement of materials properties, the CIPM meeting in October 2005 accepted the proposal to set up an ad hoc Working Group on Metrology of Materials. The Working Group is assessing a wide range of materials properties, looking particularly at the need for improved traceability routes, data comparability and the availability of appropriate reference materials. The Group will report to CIPM in October 2007, with the intention of raising the profile of materials metrology internationally and engaging the leading NMIs (National Measurement Institutes) in recognising and addressing known difficulties in demonstrating traceability of many material properties to the SI. Terms of Reference have been agreed, and the first meeting took place at the UK's National Physical Laboratory in May. This paper describes the range of properties being investigated and highlights the studies being undertaken by the Working Group members.
