This standard specifies the method of wet heating aging test of anaerobic adhesives for aviation use, including principle, equipment and materials, test pieces, test conditions, test procedures, treatment of test results and test reports. It is suitable for measuring the aging performance of anaerobic adhesives in heat and humidity air after coalescence. The test principle is to measure the torque strength or static shear strength of the test pieces in humid air at specified temperature and atmospheric pressure after aging for a certain period of time. In addition to the provisions of HB5314 or HB5315, the Conditioning test chamber and distillation water are also required as the equipment and materials required for the test. The number of specimens shall not be less than 5, and the wet heat aging test shall be carried out immediately after curing under standard environment conditions.
