IEC60068-2 High low temperature and low pressure test chamber
Product introduction:
High-low-temperature and low-pressure test chambers can be called altitude temperature and humidity test chambers, high-altitude and low-pressure test chambers, plateau environmental climate chambers, altitude temperature test chambers, high-low, low-temperature, humid-heat and low-pressure test chambers, and high-low, low-temperature and low-pressure testing machines. It is an equipment that can simulate high altitude, high altitude, and (plateau area) climate for storage, use, and transportation reliability testing, and can simultaneously energize the test piece to test electrical performance parameters.
Testing standards:
GB/T 2423.1-2008 Environmental testing of electrical and electronic products Part 2: Test methods Test A: Low temperature (IEC60068-2-1:2007, IDT);
GB/T 2423.2-2008 Environmental testing of electrical and electronic products Part 2: Test methods Test B: High temperature (IEC60068-2-2:2007, IDT);
GB/T 2423.21-2008 Environmental testing of electrical and electronic products Part 2: Test methods Test M: Low air pressure (IEC60068-2-13:1983, IDT);
GB/T 2423.22-2012 Environmental testing Part 2: Test method Test N: Temperature change (IEC60068-2-14:2009, IDT);
Test items:
1. Insulation resistance: Use a 500V megohmmeter to measure the insulation resistance of the electrical system of the high and low temperature test chamber to ensure that it is not less than 2m (when measuring the compressor alone, it should be not less than 5m) to judge its electrical safety.
2. Starting performance: Under the condition of voltage of 380V, the machine is manually started and stopped three times. Each operation and shutdown lasts for 3 minutes. Check whether protection phenomenon occurs to evaluate its starting stability and reliability.
3. Residual air in the refrigeration system: By observing and touching the temperature of the upper and lower parts of the condenser, determine whether there is residual air in the refrigeration system to ensure good cooling effect.
4. Refrigerant charge: Determine whether the refrigerant charge is normal by observing the frosting of the evaporator, the heat of the condenser, the temperature of the low-pressure suction pipe, and the operating current and temperature of the compressor.
5. Door sealing performance: Clip a new banknote anywhere on the door seal and check whether the banknote can slide to evaluate the door sealing performance.
Test object:
1. Aerospace equipment: Since aerospace equipment needs to work in extreme environments such as high altitude and extreme cold, the high-low-temperature and low-pressure test chamber can simulate these environmental conditions to test the performance and reliability of aerospace equipment.
2. Automobiles and their parts: Automobiles need to operate in various climatic conditions, including high temperature, low temperature, plateau, etc. Test chambers can simulate these environmental conditions to evaluate the performance and reliability of vehicles and their components.
3. Electronic products: The performance and reliability of electronic products such as mobile phones, computers, sensors, etc. will be affected by environmental conditions such as temperature and air pressure. The high-low-temperature and low-pressure test chamber can simulate these environmental conditions to test the stability and reliability of electronic products.
4. Medical devices: Medical devices need to operate in different environments and conditions, and their performance and reliability need to be guaranteed. The test chamber can simulate the performance and reliability of medical devices under different temperature and pressure environments.
5. Material science field: For materials, their performance and reliability under different temperature and pressure environments will also be affected. High-temperature and low-pressure test chambers can simulate these conditions and help researchers in the field of materials science conduct relevant research.
