(f) Provisions for additonal samples required because of failure of any sample(s) to pass the prescribed inspections, (g) Required data. 6.3 Definitions 6,3.1 frequency, The amplitude may refer to displacement or acceleration. The di
35、splacement is given in one half the peak-to-peak excursion in inches or the cor- responding maximum acceleration in gravity units (g). The frequency is given in cycles per second (cps). 6.3.2 Shock, Shock is an abrupt change in the position of a body, resulting from the sudden application of a large
36、 external force of short duration. Shock is described as a pulse force in units of gravitational acceleration (gls), of duration in units of time, milliseconds (ma), and a shock wave approximating a one-half sine wave. The time duration shall be measured between trvo points where two lines intersect
37、 the zero ltgft line. These lines are tangent to the shock wave slopes. Vibration. Vibration is a sinusoidal motion defined by amplitude and 6.4 of preservation, packaging, and packing shall be as follows: Preparation for delivery criteria, Criteria for use of the proper level Level A This level sha
38、ll be used for those items which are to be shipped to indeterminate destinations or stored under indeterminate .conditions for redistribution anlwhere. Level B Not applicable. Level C This level shall be used only when it is definitely known that the packaged item is to be shipped to domestic instal
39、lations for immediate use at the first receiving activity.
