What does the BAIJIAN test report do? What problems can it help you solve?

1. Sales report. (Sales need to provide third-party testing reports to make their products more unique, let the product data speak for themselves, and make customers more confident in the quality of their products.)

2. Research and development reports. (In the process of developing new products, we encountered some thorny issues about ingredients. We used third-party testing data to find the cause of the problem, solve the problem in a timely manner, shorten the R&D cycle, and reduce R&D costs)

3. Improve products quality. (Discover problems with your own products through comparison of third-party testing data, improve product problems, improve quality, and reduce production costs)

4. Use of scientific research paper data.

BAIJIAN What are the advantages of material testing laboratories?

1. Collectively owned testing institutions with complete qualifications and scientific, fair and accurate test reports.

2. Multiple laboratory branches are located across the country, supporting door-to-door sampling/sending samples for testing.

3. The testing cycle is short, the testing cost is low, and the experimental plan is more complete.

4. For initial inspection of samples, no testing fees will be charged during the initial inspection.

5. The test report supports scanning the QR code to check the authenticity.

BAIJIAN testing process

1. Send samples. (Communicate with engineers, submit your own testing requirements and send samples to our research institute)

2. Initial inspection samples. (After receiving the sample, conduct a preliminary inspection of the sample and formulate a detailed experimental plan)

3. Quotation. (After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment)

4. Both parties confirm, sign a confidentiality agreement, and start the experiment.

5. It takes 7-15 working days to complete the experiment.

6. Mail the test report and provide post-service.

The above is the relevant introduction to voltage sag testing. If you have other needs, you can consult the laboratory engineer to help you solve it.
