At present, there are really too many domestic testing agencies, whether they have laboratories or qualifications, they all come out to receive customers. Many small testing companies are actually leather bag companies. They just register a company to receive customers, and then commission the experiment to make a difference in the middle. There are some even more outrageous testing companies. They will not do experiments for you at all. They will directly falsify data and fake qualifications for you, which will cause large deviations in experimental results and affect the development cycle.

So how to choose a more formal third-party testing agency? The following editor introduces a few things that need to be understood by yourself.

1. Look at the qualifications. (First of all, look at the business license of this testing agency and the CMA and other testing qualification certificates. If you don’t have these qualification certificates, don’t consider it)

2. Look at the laboratory environment. (If it is convenient, it is better to visit the laboratory of the testing institution to see if there is an independent laboratory, and the laboratory equipment is not complete, so that the leather bag companies can be filtered out)

3. Look at the price tricky. (Don't blindly pursue low prices. You need to integrate the complexity of the experiment and have a rough estimate. If some companies tell you that the price is particularly low, you have to think about it. Consider the authenticity of the data, whether the experiment is true, etc.)

4. Look at the nature of the testing organization. (It is better to choose a testing agency, such as a collectively owned testing agency like Sinochem. This type of formality is relatively large, and the test report can be used in a wide range)

With reference to the above points, you can basically choose a formal testing organization.
