At present, most domestic environmental test equipment are produced to meet the national standard GB2423 "Basic Test Procedures for Electrical and Electronic Products".
These environmental test equipment now have corresponding product national standards, such as
GB10586-89 "Technical Conditions of Humidity and Heat Test Chamber"
GB10589-89 "Technical Conditions of Low Temperature Test Chamber"
GB10591-89 "Technical Conditions of High/Low Temperature Test Chamber"
GB10591-89 "Technical Conditions of High/Low Temperature Test Chamber" etc.
Before the 1980s, most of the environmental testing equipment used in our country was imported from Western countries, and the price was relatively expensive. Nowadays, with the development of electronic technology, especially the development of control technology, from analog control to current digital control ; The display mode ranges from pointers to numbers and then to the current touch screen display; the control accuracy is increased from ±1℃ to 0.1℃ or even within 0.01℃; the volume of the equipment varies from a small box to a room (room) of hundreds of cubic meters. , my country’s environmental test equipment manufacturers have been able to produce equipment that meets the test requirements. Performance can be comparable to imported equipment, some special equipment, such as temperature shock equipment, rapid temperature change (15°C/min) domestically produced equipment can already meet the requirements.
