6.3.5 Acceleration (steady state). Acceleration (steady state)
is the time rate of change of velocity of a body resulting from the
application of a sustained external force with a uniform buildup to
peak in more than 0.010 second.  Acceleration is given in gravitational
units.
6.3.6 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 buildup to
90 percent of peak force in less than 0.010 second.  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 wave form builds up, to its decay to zero amplitude.
6.3.7 Temperature.  The temperature of the environment to which
the valve is exposed, is expressed in degrees Fahrenheit (F).
Humidity is the relative humidity of the environ-
6.3.8 Humidity.
ment to which the valve is exposed, expressed in percent.
6.3.9 Valve.  This term refers to the complete explosive valve
unit, which includes the independent, electrically fired squib assembly
contained in the valve body.
6.3.10 Sample squib.  This term refers to serarate sample quibs
submitted with each lot of valves for preproduction or quality
conformance testing.
6.4 Suitability.  Any valve which has been subjected to a non-firing
current in excess of the continuity test current of 0.200 ampere shall
be considered unsuitable for service use and shall be expended.
The weight of the valve shall not exceed 0.5 pound.
6.5 Weight.
6.6 The margins of this specification are marked with an asterisk to
indicate where changes (additions, modifications, corrections, deletions)
from the previous issue were made.  This was done as a convenince only
and the Government assumes no liability whatsoever for any inaccuracies
in these notations.  Bidders and contractors are cautioned to evaluate
the requirements of this document based on the entire content irrespective of
the marginal notations and relationship to the last previous issue.
