Many car owners are equipped with an in car vacuum cleaner, and sometimes the vacuum cleaner cannot work at low temperatures because the product has not undergone high and low temperature environmental testing. According to the industry standard of CAB 1021-2013, car mounted vacuum cleaners need to pass high and low temperature tests
Test sample: Car mounted vacuum cleaner
Test equipment: Constant temperature and humidity test box (HYH-80)
Meet the standard: CAB 1021-2013
Test requirements:
1. Power supply voltage: The fluctuation of DC power supply voltage should not exceed ± 1% of the rated voltage;
2. Testing instruments: Measuring instruments, the accuracy of the instruments should not be less than 0.5 level, and the accuracy of the instruments used for factory inspection should not be less than 1.0 level
High and low temperature test of automotive vacuum cleaners:
1. High temperature test:
Set the temperature of the high and low temperature test chamber to (55 ± 2) ℃. After the temperature stabilizes, place the sample in the test chamber for more than 3 hours. After the test, the sample can start normally without any faults
2. Low temperature test:
Set the temperature of the high and low temperature test chamber to (-20 ± 2) ℃. After the temperature stabilizes, place the sample in the test chamber for more than 3 hours. After the test, the sample can start normally without any faults
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 problemsBaijian 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:
1. The testing industry is fully covered, meeting different testing needs
2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate
4. Free initial testing, with no testing fees charged
5. Self service order delivery for free on-site sampling
6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in China
