Acceleration (steady state). Acceleration (steady state) is
the time rate of change of velocity of a body resulting from the applica-
tion of a sustained external force with a uniform build-up to peak in
more than 0.010 seconds. Acceleration is given in gravitational units.
Shock . Shock is an abrupt change in the motion of a body
resulting from the sudden application of a large external force of short
duration. Shock, in general, can be described as a build-up to 90 per-
cent 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 the
pump is exposed, is expressed in degrees Fahrenheit.
Humidity. Humidity is the relative humidity of the environ-
ment to which the pump is exposed, expressed in percent.
Salt solution. The salt solution shall be prepared by
dissolving 3 parts, by weight,of sodium chloride in 97 parts, by weight,
of tap water.
The weight of the pump shall not exceed 2 pounds.
Packed and packaged condition. The pump shall be capable of
with-standing storage for 5 years in the packed and packaged condition and,
thereafter, meet the performance requirements of this specification.
