How to choose environmental test equipment
First, the type of environmental test equipment
(1) Climatic environment testing equipment
High and low temperature test chamber: Through the heating and refrigeration system, the temperature in the box can be accurately controlled to achieve the test of the product in different high and low temperature environments.
Constant temperature and humidity test chamber: The use of temperature and humidity control system to create a stable temperature and humidity environment in the box.
Waterproof test chamber: Through the sprinkler system to simulate natural rain or specific rain environment, you can control the intensity of rain, rain size and rain Angle and other parameters.
Dust test chamber: the dust is blown up through the air blast system to form a dust environment in the box, which can control the concentration of dust, particle size and wind speed and other parameters.
(2) mechanical environment testing equipment
Impact test chamber: Generate instantaneous impact force through free fall, gas or liquid, etc., to simulate the impact situation that the product may encounter in the process of transportation and use.
Vibration test chamber: Through vibration frequency, amplitude and acceleration and other parameters, simulate the vibration environment that the product may encounter in the process of transportation and use.
(3) Comprehensive environmental testing equipment
Three comprehensive test box: The comprehensive test box is a highly integrated test equipment, which combines the three environmental factors of temperature, humidity and vibration in one, and is used to simulate complex environmental conditions to test the performance of materials, electrical, electronic products, and various electronic components under these conditions.
Three comprehensive vibration test box: three comprehensive vibration test box combined with temperature, humidity, vibration function in one, suitable for aerospace products, information electronic instruments and meters, materials, electrical, electronic products, various electronic components in a comprehensive harsh environment to test their performance indicators.
Second, the selection of environmental test equipment guide
(1) Selection according to product testing requirements
Product type: Different types of products have different requirements for environmental testing equipment. For example, electronic products often need to be tested for high and low temperatures, heat and humidity, and vibration to ensure performance and reliability under a variety of environmental conditions.
Application environment: Consider the actual environmental conditions of the product. If the product is used in harsh outdoor environments, it may be necessary to have a variety of environmental test equipment such as waterproof, dust proof, high and low temperature, vibration, etc.
(2) Selection according to test standards
Industry standards: Each industry has its own environmental testing standards. For example, the automotive industry has standards such as ISO 16750 that specify the environmental testing requirements for automotive parts.
International standards and national standards: For some products, international standards and national standards are also considered. For example, in the testing of electrical equipment, it is necessary to meet the requirements of IEC (International Electrotechnical Commission) and GB (Chinese National Standard) relevant standards.
(3) Consider equipment performance parameters
Test range: The test range of the equipment should meet the needs of product testing. For example, the temperature range of the high and low temperature test chamber should cover the lowest and highest temperatures that the product may encounter.
Accuracy: The accuracy of the equipment directly affects the accuracy of the test results. For example, the temperature and humidity accuracy of the constant temperature and humidity test chamber should meet the test requirements, and the temperature accuracy is ±2 ° C and the humidity accuracy is within ±1%RH of the test chamber (specific changes are made according to demand).
(4) Equipment reliability and after-sales service
Reliability: Select equipment with good quality and reliability. You can evaluate the reliability of the equipment by looking at the brand reputation of the equipment, user evaluation and other ways.
After-sales service: Good after-sales service is an important guarantee for the use of equipment. Including equipment installation, training, maintenance, spare parts supply and so on. For example, when there is a problem with the equipment, the supplier is able to provide timely repair services, on-site inspection of the equipment and provide training on the operation of the equipment.
