The GJB 715.1-1989 standard specifies a method of salt spray testing fasteners in simulated high Humidity and salinity environments to assess their corrosion resistance. The test involves the use of a special Salt Spray Tester, which should have a liquid salt atomization device, heating and temperature control devices, and an air humidification device. The test chamber material must have anti-salt fog corrosion characteristics, and all parts in contact with the sample should be protected from electrochemical corrosion. Through this test, the durability of the fastener in the salt fog environment can be effectively determined to ensure its long-term performance.
