European reference materials ERM
歐洲標(biāo)準(zhǔn)局標(biāo)準(zhǔn)物質(zhì)Institute of Reference Materials and Measurement
Three major European reference materials producers have combined forces to produce a brand new standard in reference materials to ensure reliability and comparability of the results of chemical analysis.
European Reference Materials are certified materials, which undergo uncompromising peer evaluation and offer highest quality and reliability.
They are a major tool for improving the confidence in, and the mutual recognition of test results and certificates in a global market. CRMs comply with high metrological requirements, ensuring traceability of measurements results, and are the end-point of the traceability chain, thus being primary standards in chemistry.
