Introduction

"International Bureau of Metrology (BIPM), International Organization for Legal Metrology (OIML), International Laboratory Accreditation Cooperation Organization (ILAC) and the International Organization for Standardization (ISO) Joint Statement on Metrological Traceability Consistency and comparability are required. Only when the measurement results are traceable to internationally recognized reference standards can the Consistency and comparability of measurement results. A certified reference material is one or more characteristics that are obtained using effective procedures and have uncertainty and traceability. The reference material of the performance value is an important tool for establishing the measurement traceability of measurement results and achieving measurement comparability. As a kind of test The measurement traceability of its characteristic value itself needs to be established, maintained and maintained in accordance with general principles. Standardized expression in his documents. The development unit of certified reference materials shall be able to provide supporting evidence for the traceability of the measurement of characteristic values. This specification is digesting and absorbing ISO /IEC Guide 99 "International Metrology Vocabulary Basic Concepts and Related Terms (VIM), ISO Technical Report 16476 "Measurement Traceability of Characteristic Values Assigned to the Establishment and Expression of Reference Materials", IUPAC Technical Report "Metrical Traceability of Chemical Measurement Results. Concept and Implementation", EURACHEM/CITAC The basis for international documents such as the Guide "Metrical Traceability of Chemical Measurement Results to Achieve Comparable Chemical Measurement Results" Established above, it is a national measurement of my country's JJF 1342, JJF 1343, JJF 1186, JJF 1218 and other standards related to the country Refinement of the traceability requirements for measurement in the technical specifications. This specification is released for the first time. Establishment, evaluation and expression of metrological technical specifications for the traceability of reference materials

1 Scope

This specification applies to the establishment, maintenance and evaluation of the traceability of characteristic values in the development and production of national reference materials. And the accurate expression in the reference material development report, certificate and other documents. This specification can also provide reference for users of reference materials, certification and accreditation and other related organizations.
