High and low temperature test chambers are essential testing equipment in fields such as aviation, automobiles, home appliances, scientific research, etc., used to test and determine the parameters and performance of electrical, electronic, and other products and materials subjected to high temperature, low temperature, or constant temperature environmental changes during testing
Concept of High and Low Temperature Testing
High and low temperature testing is a method used to determine the adaptability of products to storage, transportation, and use under high or low temperature climatic conditions.
. The severity of the experiment depends on the temperature and duration of exposure at high or low temperaturesIntroduction to High and Low Temperature Testing
1. High temperature testing
High temperature testing is used to determine the adaptability of products to storage, transportation, and use in high-temperature climatic conditions.
. The severity of the experiment depends on the high temperature and exposure duration Reference testing standards: GB/T 2423.2, IEC 60068-2-2, IEIA 364, MIL-STD-810F, etc2. Low temperature test
Low temperature test is used to determine the adaptability of products to storage, transportation, and use in low-temperature climatic conditions.
. The severity of the experiment depends on the low temperature and exposure duration Reference testing standards: GB/T 2423.1, IEC 60068-2-1, EIA 364, MIL-STD-810F, etc3. Temperature shock test
Temperature shock test is to determine the adaptability of products to storage, transportation, and use in rapidly changing climate environments.
. The severity of the test depends on high/low temperature, dwell time, and number of cyclesReference testing standards: IEC60068-2-14, GB2423.22, GJB150.5, etc.
4. Rapid temperature change test
Rapid temperature change test is the adaptability of products to storage, transportation, and use in high temperature, low temperature, fast or slowly changing climate environments.
. The test process is a cycle of room temperature → low temperature → low temperature residence → high temperature → high temperature residence → room temperature. The severity of the temperature cycling test is determined by the high/low temperature range, residence time, and number of cyclesFunction 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
