The national standard material is a substance or material that has been determined to have one or more sufficiently uniform characteristic values, which is used as a "measuring tool" in the analytical measurement industry to calibrate measuring instruments and devices, evaluate measurement analysis methods, measure the characteristic values of substances or materials and assess the operational technical level of analysts. As well as in the production process of product quality control and other fields play an indispensable role. So what are the main functions of national standard substances? The following is a small edition of Bolinda to introduce you.

What are the main functions of national standard substances?

1, I believe that many people have understood that under normal circumstances, the measurement of national standard substances is characterized by accuracy, uniformity and stability, so by using national standard substances, the actual measurement results can be obtained to a large extent.

2, in the process of calibration of measuring instruments and evaluation of measurement, the national standard material can trace the measurement results to the international System of Units, so as to effectively ensure the consistency and comparability of measurement results, and finally achieve the unity of quantity value.

3, In addition, we need to know that national standard substances 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.

4, finally, it is also a very important role, in the production process, from the inspection of industrial raw materials, process control to waste treatment and utilization and other aspects, generally need a variety of corresponding national standard substances, to ensure the reliability of the results, so as to effectively improve product quality.

The above content is the main role of the national standard material reflected in what aspects of the introduction, the national standard material in many measurement areas have a more extensive application, now in many laboratories, we can see its figure.
