3.6 Leak test. Each head assembly shall pass the leak test specified in 4.4.6.5.
3.7 Radiographic. Each loaded rocket catapult shall be examined radiographically to ascertain the
presence, condition, and correct placement of internal components.
3.8 Protective finish. Protective finish shall be in accordance with the applicable specifications and
drawings and shall apply to all surfaces of the component regardless of configuration.
3.9 Residual magnetism. The rocket catapult assembly, when passed in front of an SAE AS 17983
compass along the entire length of the catapult (see figure 2), shall not cause the compass indicator to
deflect more than 5 degrees in either direction. This test shall be performed in an area free from local
magnetic effects.
3.10 Environmental. The rocket catapult assemblies shall withstand the environmental conditioning of
3.10.1 through 3.10.4. Rocket catapult assemblies subjected to this conditioning shall show no evidence
of deterioration of propellant or disarrangement of components when examined in accordance with
4.4.6.1 and shall meet the ballistic performance requirements of 3.4 when test fired in accordance with
4.3.2.
3.10.1 High temperature. The rocket catapult shall withstand the high temperature test of 4.3.1.1.
3.10.2 Vibration. The rocket catapult shall withstand the vibration test of 4.3.1.2.
3.10.3 Temperature-shock. The rocket catapult shall withstand the temperature-shock test of 4.3.1.3.
