3.4 Functioning output pressure/time test. The pressure cartridge
shall function on the first attempt and shall produce a pressure of 450
psig minimum (rein) for a time duration of 75 milliseconds (ins), when
fired in a T-bomb with an internal volume of 0.049 cubic inches
The time to peak pressure shall be 50 ms maximum (max) after application
of the ignition pulse and the peak pressure shall be 2400 psig max (see
fig 1). The cartridge shall function when temperature conditioned as
specified in 4.5.8.
3.5 Insulation resistance.
3.5.1 Insulation resistance of pressure cartridge assembly. The
insulation resistance between the shorted (twisted) electrodes and the
case shall be 50 megohms rein, at 325 volts direct current (vdc) when
tested as specified in 4.5.4.
3.5.2 Insulation resistance, thermal shock and vibration and
function. The pressure cartridge shall comply with the insulation
resistance requirements of 3.5.1, and shall function on the first attempt
when tested as specified in 4.5.5.
3.6 First article inspection. This specification contains technical
provisions for first article inspection. Requirements for the submission
of first article samples by the contractor shall be as specified in the
3.7 Workmanship. All parts and assemblies shall be fabricated, and
assembled in a thorough, workmanlike manner. They shall be free of
burrs, chips, sharp edges, cracks, surface defects, dirt, grease, rust,
corrosion products and other foreign matter. The cleaning method used
shall not be injurious to any part nor shall the parts be contaminated by
the cleaning agent. Exterior surface coatings shall be continuous;
however, a few light scratches not exposing base material may be
permitted. All required markings shall be neat and sharply defined.
