Introduction

As a kind of measurement standard, reference material plays an important role in the traceability and transmission of measurement values in the fields of chemistry and biology. very important role. The reliability of the quality value of the standard substance is to ensure that the standard substance is used as a tool to achieve accurate measurement results, comparable premise. Standard substance measurement comparison can be used for. 1) Supervision and management of national reference materials; 2) External evaluation and certification of the reference material development (production) organization's reference material preparation and value determination capabilities; 3) Provide objective evidence of traceability, compatibility and equivalence of the characteristic values of reference materials. This specification starts from the characteristics of reference materials and their development (production), and refers to domestic metrological comparison and chemical measurement. It is formulated on the basis of the quantity comparison specification and the international measurement comparison documents related to standard substances. The specification stipulates the standard substance The basic types of metrological comparisons, as well as the technical principles and methods followed in carrying out the metrological comparisons of standard substances, are Based on the premise of traceability guarantee, it provides a technical basis for the measurement comparison in the field of reference materials, and it can also provide a basis for standard materials. Provide technical reference for activities such as quality value verification. This specification is published for the first time.
