Acceleration (steady state). Acceleration (steady state)
6.3.5
is the time rate of change of velocity of a body resulting from the
application 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
6.3.6
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
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. Duraction is defined
as the interval between the point of zero amplitude, from which the shock
waveform builds up, to its dacay to zero amplitude.
6.3.7
Temperature. The temperature of the environment to which
the valve is exposed, is expressed in degress Fahrenheit.
Humidity. Humidity is the relative humidity of the environ-
6.3.8
ment to which the valve is exposed, expressed in percent.
Valve. This term refers to the complete explosive valve unit
6.3.9
which includes the independent, electrically fired squib assembly con-
tained in the valve body.
Sample squib. This term refers to separate sample squibs
6.3.10
submitted with each lot of valves for preproduction or acceptance
testing.
Suitability. Any valve which has been subjected to a non-
6.4
firing current in excess of the continuity test current of 0.200 amperes
shall be considered unsuitable for service use and shall be expended.
Weight. The weight of the valve shall not exceed 0.5 pounds.
6.5
6.6
Storage life.
Packed and packaged condition. The valve shall be capable of
6.6.1
withstanding storage for 5 years in the packed and packaged condition and
thereafter, meet the performance requirements of this specification.
6.7
General safety Precautions.
