I don't know if you are familiar with the standard sample, in fact, it is what people call the physical standard or standard sample. Moreover, it is developed according to the need of implementing and formulating character standards. As a supplement to character standards, it is a kind of standard material agent of the Institute of Chinese Medicine Standard Reference Products.

In short, it is a standard substance that is often used as a reference. Perhaps many people have doubted whether the reference standard value provided by the standard sample is credible, the answer is of course yes, and the standard value provided is also very accurate. So, what are the characteristics of the standard value provided by the standard sample? Next, Bolinda Xiaobian to introduce you.

What are the characteristics of the standard value provided by the standard sample:

1, with enough uniformity. Please note that it is not very uniform but uniform enough. Because the standard sample is only to ensure the consistency of the application effect of the technical standard in different space applications, that is, to meet the requirements of the technical indicators in the text standard.

2. It's well established. It should also be noted here that what is said is not very clear but very well determined, that is, the standard value is required to be reliable. In fact, one of the meanings of "well established" is that the standard sample should have sufficient stability to ensure the transfer of quantity values at different times. That is to ensure that it is uniform and reliable within the validity period.

These are the two characteristics of the standard value provided by the standard sample introduced by Xiaobian, and I hope to provide the corresponding help for the majority of friends who want to buy the standard sample.
