Vehicle vibration definition
Vehicle vibration. The test levels and the test method for this element of the distribution cycle are intended to determine the ability of the shipping unit to withstand the vertical vibrations environment during transportation. The test levels and test method account for the frequency range, amplitude, sweep rate, dwell time for resonance's, and direction of vibration. Conditioning--See SECTION 6** Special instructions--Perform the test for each possible shipping orientation. Dwell time for each noted package or product resonance up to four discrete resonance's. Test at the four frequencies where the greatest response is noted. In frequency sweeps it is advisable to consider the frequency ranges normally encountered in the type of transportation being considered. Use the following test levels:
