Today, advanced laboratories test for temperature and humidity, high temperature, low temperature and temperature cycling. High-temperature and low-temperature testing is used to test a product's strength for long-term storage or operation in these environments. Temperature cycling between high and low temperatures accelerates thermal fatigue of solder joints, gaskets and joints on the product.
The temperature range in the multiple temperature and humidity test chambers used to conduct these tests is generally between minus 70 degrees and plus 180 degrees. The rate of temperature change is 15 degrees per minute. These test chambers also have an oven with a capacity of 400 degrees. Meanwhile, it has low and high humidity ranges between 10 percent at 10 degrees and 85 percent at 98 degrees.
In high temperature and low temperature tests, the performance properties of sample materials against temperature cycles are determined. These tests are carried out according to the current standards or the specifications requested by the manufacturer, and various performance indicators are determined. Incompatibilities between the components of different materials due to different thermal expansion rates or the susceptibility of a product to structural deterioration due to thermal shock are determined.
Advanced labs offer temperature exposure testing capabilities, including but not limited to:
International Electrotechnical Commission (IEC) standards for preconditioning, post-test conditioning, temperature rise rate, constant temperature definition, temperature load condition, unit tested and chamber volume ratio, and similar conditions to accurately examine and verify product performance under various temperature conditions. determined.
Generally, test applications are divided into low temperature storage testing and low temperature operating testing. A cold start test is recommended in the low temperature test to verify whether the material being tested can be started at low temperature. From experience, most products do not work in cold weather. More accurate results are obtained if the product is tested using low voltage during low temperature testing. The usual effects of low temperatures are failure to start, cracking of material, brittle glass products, jamming of moving parts, changes in lubrication, and similar effects.
Temperature is the inevitable stress that every product experiences during the testing phase after development. How the product or material responds to the stress effect may differ from each other. Every manufactured product must pass temperature qualifications, life testing and other additional evaluations before being placed on the market.
The high and low environmental chamber, which tests the effects of different environmental conditions on products and materials, helps manufacturers ensure the safe use of new development. Without the high and low temperature environmental chamber, which ensures the reliability of newly developed products by mimicking the effects of various environmental conditions to determine their response at an early stage, consumers will likely buy a product that could endanger their lives. So the benefits of testing with a high and low environmental chamber are limitless with the type of electronics, machinery, and other things people use every day.
Environmental chambers have different features that include high temperature and low temperature testing capabilities. Both low and high temperature ambient chambers can test products and materials differently at a certain temperature.
High and low temperature ambient chambers test products and materials at different temperatures due to their design suitable for adapting to a higher temperature in a closed chamber. High and low temperature ambient chambers are designed to withstand varying degrees of temperature testing, whether extremely high or low.
Among the numerous test, measurement, analysis and evaluation studies given to businesses by our organization, there are high temperature and low temperature testing services.
