(Sell your own products, issue a third-party test report to make customers trust your product quality more, make your products more convincing, and make yourself more convincing in terms of sales) 2. R&d and use. (In the process of research and development, I encountered some thorny problems and solved them through testing report data, so as to shorten the research and development cycle and reduce the cost of research and development) 3. Improve product quality. (Through the comparison of test data, find out the problems of their own products, improve product quality, and reduce production costs) 4. Simulated production. (Through the formula testing service, testing better products in the same industry, to achieve simulated production) 5. Data use of scientific research papers. 6, bidding, bidding use.
