percent of peak force in less than 0.010 seconds. Shock is described as
a pulse in units of gravitational acceleration, duration in milliseconds
and shock wave form Equivalent to one half sine wave. Duration is defined
as the interval between the point of zero amplitude, from which the shock
waveform builds up, to its decay to zero amplitude.
Temperature. The temperature of the environment to which
6.3.7
the valve is exposed, is expressed in degrees Fahrenheit.
Humidity. Humidity is the ralative humidity of the environ-
6.3.8
ment to which the valve is exposed, expressed in percent.
