How to do the test report? Why do you need to do product inspection? Third-party testing institutions provide product testing services in various industries, and there are many cooperative laboratories across the country, mainly serving companies, enterprises, individual businesses, universities and scientific research.
Testing process
1, sending samples
2, checking requirements
3, targeted quotation
4, both parties determine, sign a contract, start
the experiment5, complete the experiment: the testing cycle (can be expedited) will be changed according to the sample and its testing items / methods, you can consult the engineer
6, issue a test report, and provide post-service.
The low-temperature test specified in this part of GB/T2423 is applicable to non heat dissipation and heat dissipation test samples. There is no substantial difference between Experiment Ab and Experiment Ad from earlier versions The main purpose of adding test Ae is to detect equipment that requires power to operate throughout the entire testing process, including the cooling adjustment period.
The purpose of this low-temperature test is limited to determining the ability of components, equipment, or other products to be used, transported, or stored in low-temperature environments.
This low-temperature test cannot be used to evaluate the resistance of test samples to temperature changes and their ability to operate in temperature changing environments. In this case, GB/T 2423 should be used 22.
This low-temperature test method is divided into the following categories:
Low temperature test on a non heat dissipation test sample:
● Test Ab, temperature gradient.
Low temperature test of a heat dissipation test sample:● Test Ad, temperature gradient
● Test Ae, temperature gradient, and the test sample is energized throughout the entire test process The test methods given in this section are usually used for test samples that can achieve temperature stability during testing
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problems100% inspection and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
