A reference substance is a highly uniform, well stable and quantitatively accurate measurement standard, a material or substance with one or more sufficiently uniform and well defined characteristic values for the purpose of calibrating equipment, evaluating measurement methods or assigning a value to the material. So what does a reference material do? The following is a small edition of Bolinda to introduce you.

The main functions of reference materials are:

1, save and transfer the characteristic value, establish the measurement traceability

The standard material is a measurement standard with accurate, uniform and stable characteristic value, and has the characteristic value maintained in time. The function of transmitting quantitative values in space. By using the standard material, the actual measurement results can be obtained.

2. Ensure the consistency and comparability of measurement results

By calibrating the measuring instrument and evaluating the measuring process, the consistency and comparability of the measuring results from the source to the class are achieved through the standard material.

3. Research and evaluation of measurement methods

The reference material can be used as a substance with known characteristic value to study and evaluate the method of measuring these components or characteristics, so as to judge the accuracy and repeatability of the method, and evaluate the adaptability of the detection method in specific occasions by verifying and improving the accuracy of the measurement method, so as to promote the development of calibration methods and test techniques.

4. Ensure the smooth conduct of product quality supervision and inspection

In the production process, from the inspection of industrial raw materials, the control of process flow, the evaluation of product quality, the trial production of new products to the treatment and utilization of Sanling, various corresponding standard substances are needed to ensure the reliability of the results, so that the production process is in a good quality control state, and effectively improve the quality of products.

The above content is the introduction of the role of the standard material, the standard material in different countries and different periods to ensure the consistency of measurement results, comparability, to ensure the transmission of quantitative values and can be traced back to the unity of the international system of measurement units. Reference materials also play an important role in the transmission of certain characteristic values, calibration of measurement instruments, evaluation of measurement methods, and reduction of interference factors in measurement.
