Science and technology is the first productive force of the people, and aerospace technology is a highly comprehensive high-tech group, which gathers many of the latest achievements of science and technology in the world today. With the development of the domestic aerospace industry, products from various industries such as If you want to use it in aerospace and other fields, you must do a low-pressure test. Below, Lin Pin Instruments briefly describes the low-pressure test chamber military equipment environmental test method. Low-pressure (altitude) test GJB150.2-86 standard.
This standard specifies the low-pressure test method for military equipment, which is the basis and basis for the selection of the corresponding parts of technical documents such as technical conditions or product standards for military equipment. The low-pressure test chamber refers to this standard for test testing and is suitable for use as a cargo on aircraft. The equipment transported in the ballast, the equipment installed and working in the high altitude area, the purpose of the test is to determine the adaptability of the equipment to the low pressure environment during storage, transportation and use, the test pressure (storage test: 57kPa simulated 4550m altitude (test Duration: not less than 1H), working test: 57kPa simulated 4550m altitude (time required for performance testing), rapid decompression test: 18.8kPa simulated 12200m altitude (test duration not less than 10min)), pressure change rate (storage Test is not greater than 10kPa / min, working test is not greater than 10kPa / min), rapid decompression test (a, decompression time is not greater than 15s, pressure recovery speed is not greater than 10kPa / min). The requirements for the test chamber in the standard and can be implemented The test procedures and other indicators have also made detailed requirements, if you need to understand the detailed standard content, please under the standard of this site Download column.
