Under normal circumstances, the measurement of standard substances is characterized by accuracy, uniformity and stability, so the actual measurement results can be traced to a large extent by using standard substances. In the process of calibrating the measuring instrument and evaluating the measurement, the reference material can trace the measurement results to the International System of Units, so as to effectively ensure the consistency and comparability of the measurement results, and finally achieve the unity of the quantity value. Next, Bolinda introduces the main uses of reference materials.

Salient features of reference materials:

1. For measurement purposes;

2, with the accuracy of the quantity value;

3, the accuracy of its large quantity value can be traced to the relevant national measurement standards.

Main uses of reference materials:

1. Transfer quantity and value in time and space;

2. Ensure the reproduction of some basic units and derived units in the International System of Units;

3, reproduce and transfer certain engineering characteristics and physical, physical and chemical characteristics;

4, the application of the corresponding standard substances in the analysis and measurement (including purity measurement and chemical composition measurement) can greatly improve the reliability of the analysis results;

5, in the product quality assurance to ensure the accuracy, fairness and authority of the data issued.

The above content is an introduction to the main uses of reference materials, in addition, we need to know that reference materials can also be used as substances with known property values, and then used for research and evaluation to measure these components or properties. In this way, the accuracy and repeatability of the method can be judged, and the accuracy of the measurement method can be verified and improved to achieve a certain adaptability.
