Today's domestic standard environmental test equipment is produced in accordance with the national standard GB2423 "Basic Test Regulations for Electrical and Electronic Products". Our most common knowledge is: GB10586-89 "Damp Heat Test Chamber Technical Conditions", GB10589-89 "Low Temperature Test Chamber Technical Conditions" , GB10591-89 "High / low temperature test chamber technical conditions", GB10591-89 "High / low temperature test chamber technical conditions", etc.
According to the environmental factors simulated by environmental test equipment, it can be roughly divided into: climate environment equipment (including biological environment test equipment), mechanical environment test equipment, climatic machinery comprehensive environmental test equipment and other environmental test equipment.
However, environmental testing equipment is still a precise and valuable equipment. Proper use and operation of environmental testing equipment can not only provide an accurate basis for inspectors, but also enable the long-term normal operation of environmental testing equipment and extend the service life of its equipment. When doing environmental tests, you must be familiar with the required sample performance, test conditions, test procedures and test techniques, the technical performance of the test equipment used, and the structure of the equipment, especially the control The operation and performance of the device should be familiar. Also read the operation manual of the test equipment carefully, so as to avoid the abnormal operation of the test equipment caused by the operation error and damage the test sample, and the test data is incorrect.
Since the 1980s, most of the environmental testing equipment used in China has been imported from Western countries, and the price is relatively expensive. Now, with the development of environmental testing industry technology, especially the development of control technology, from analog control to the current Digital control; display method from pointer to digital to the current touch screen display; control accuracy is improved from Â± 1 â„ƒ to 0.1 â„ƒ or even within 0.01 â„ƒ; equipment volume from a small box to a few hundred cubic meters (( Laboratory), China's environmental test equipment manufacturers have been able to produce equipment that meets the test requirements. Performance can be comparable to imported equipment, and the price is only about half of imported equipment.
There are many types of environmental test equipment, but the most widely used environmental test equipment is high temperature, low temperature, and humid heat test chambers. Today, it is more popular to combine high temperature, low temperature, and humid heat test boxesâ€”high and low temperature humid heat test chambers, and its repair The difficulty is greater than that of other environmental testing equipment and is representative.
