gjb1621.7A-2006 Environmental Adaptability Requirements and Test Methods.
1. Overview. gjb1621.7A-2006, that is, environmental adaptability requirements and test methods, is the standard for the performance stability of electronic, electrical and other products in various harsh environments and test methods specifications. This standard is designed to ensure that military equipment can work normally under various complex and harsh environmental conditions and meet the needs of actual combat. This article will explain the environmental adaptability requirements and test methods of the standard in detail.
2. Environmental adaptability requirements.
1.Temperature adaptability.
gjb1621.7A-2006 requires military equipment to work normally in the temperature range of -55 +125 without loss of performance and damage. Within the above temperature range, military equipment should be able to start, operate and stop normally, and the performance parameters should comply with the relevant regulations.
2.Humidity adaptability.
According to the standard, military equipment should be able to work normally in an environment with a relative humidity of 95% to 100%, and there should be no condensation, leakage and other phenomena. In high humidity environments, military equipment should be able to maintain stable performance.
3.Vibration adaptability.
gjb1621.7A-2006 requires that military equipment should be able to withstand the effects of a vibrating environment. During the vibration test, the military equipment should be able to start, operate and stop normally and should not be functionally damaged. For the vibration adaptability requirements, the corresponding test conditions and methods should be formulated according to the actual situation of the product.
4.Electromagnetic compatibility.
Military equipment should have good electromagnetic compatibility to cope with the effects of a complex electromagnetic environment. Under the condition of electromagnetic interference, military equipment should be able to maintain stable performance without problems such as abnormal operation and data loss. For electromagnetic compatibility requirements, the corresponding test conditions and methods should be formulated according to the actual situation of the product.
3. Test methods.
1.Temperature suitability test.
Temperature suitability tests should be carried out in test chambers in which military equipment is placed within the specified temperature range. During the test, the working status, performance parameters and whether there is damage to the military equipment should be observed and recorded. Based on the test results, it is judged whether the military equipment meets the requirements for temperature adaptability.
2.Humidity suitability test.
The humidity suitability test should be carried out in a constant temperature and humidity test chamber. During the test, humidity conditions should be controlled, and the working status, performance parameters, and whether there is condensation, leakage and other phenomena of military equipment should be observed and recorded. Based on the results of the tests, it is judged whether the military equipment meets the requirements for humidity adaptability.
