The high and low temperature impact test chamber can be mainly doing two tests, respectively. Impact test and circulating test, these two test methods are very different, and the following small series give you detail:High and low temperature impact test boxes are metals, plastics, rubber, Electronic material industry * test equipment for testing material structures or composites, the degree of endurance can endure under the instantaneous and extremely low temperature continuous environment, can detect the test sample in a short time in ZUI Chemical changes or physical injuries caused by zooming.
The high and low temperature impact test chamber circulation test is to reduce the resort from normal temperature to low temperature and then warm, constant temperature, and this cycle is promoted. Such tests are mostly used in electronic products or communication tools to test, and the test products can be in high temperatures such as: Saudi, Yemen, Oman, India, Sri Lanka, Maldives, Bangladesh, etc. Low temperatures are mainly suitable for regions such as Russia, cold, and check whether products are adapted to a variety of different environments, thus judge the sales market for newly developed products. The difference in impact test and circulating test of high and low temperature impact test chambers is mainly different. The impact test mainly examines the failure caused by creep and fatigue damage, and the temperature cycle mainly examines the failure caused by shear fatigue. The cycle test can be tested with a normal high and low temperature test box. The principle of the impact of temperature impact test chamber: reflow, dry, re-process, repair, etc., the severe temperature changes in the repair process. Because impact tests have strong destructive requirements for the performance requirements of the product, it is generally applicable to military units or companies to do product development.
