National standard material refers to the standard material used for uniform quantity value. Reference materials for harmonizing quantity values include reference materials for chemical composition analysis, reference materials for measurement of physical and physicochemical properties, and reference materials for measurement of engineering and technical properties. So what are the distinctive characteristics of national reference materials? The following is a small edition of Bolinda to introduce you.

What are the significant characteristics of the national standard material:

1, the quantity of the standard substance is only related to the nature of the substance, different material characteristics and differences will affect the quantity and evaluation effect of the whole substance, so these standards have nothing to do with the quantity and shape of the substance, and are rarely affected by the external structure.

2, the standard material has good reproducibility, can be self-recovery after certain damage or other problems, can be prepared in batches, if used up can also be reproduced according to the conditions.

3, there are many kinds of substances, because the national standard substances involve a lot, so the different kinds of standard coefficients are more, only the chemical component of the standard substance is thousands, its range of limits across 12 orders of magnitude, not to mention several other aspects.

4, the practicality of the standard material is very strong, can be used according to different substance types and functions of certain applications, can be used to evaluate the accuracy of the measurement method, can also be used for the quality evaluation of the measurement process and laboratory measurement certification and measurement arbitration, and different products are different.

Of course, due to the different situation of the standard material in the whole country, we can not completely uniform the special division of its standard material, more or need to look at the macro as a whole, one is based on the purpose of measurement, and the other is based on the accuracy of the quantity value. These two points together constitute the general characteristics of the whole matter.

The above content is the introduction of the national standard material has what significant characteristics, when you want to buy about the national standard material in the standard material and other products, the choice of business must be a regular company, to avoid you to buy irregular products, for your after-sales service also provides protection.
