4. Test method4.1 Rigid body jig for fixing the unit to be testedThe rigid body jig itself shall be resonance-resistant and provided with a sufficient rigidity. The acceleration at the mounting sections shall be in the range of 9.8 ± 0.98 m/s2 {1 ± 0.1G} under oscillation of 15 Hz, 9.8 m/s2 {1G}.4.2 Vibrating methodVibrate the unit to be tested by the equipment for the durability test on the bench. The vibration tests shall be made according to the vibration frequency and programs shown below. Select an appropriate number of cycles depending on the part.4.2.1 Vibrating frequency15 Hz constant4.2.2 Vibration program
