4.4.7 Spot peening check. To determine conformance to 3.5.5, the shot peening operation
shall be observed for proper shot size intensity and control.
4.4.8 Presetting check. To determine conformance to 3.5.6, the presetting operation shall be
observed for proper application of procedure.
4.4.9 Cleaning, priming, and tape covering check. To determine conformance to 3.6.1,
3.6.2, and 3.6.3, each torsion bar spring shall be checked for proper cleaning, priming and tape
covering.
4.4.10 Serration protection check. To determine conformance to 3.6.4, all serrated ends shall
be checked for proper protection.
*
4.4.11 Control tests. Control tests for maintaining control of these requirements where
inspection would be of the long durations to be included under acceptance tests shall be conducted by
the contractor as specified herein.
4.4.11.1 Frequency. For this test, one sample from the first produced of each size shall be
selected from each identifiable heat, and subjected to endurance test (see 4.4.11.3).
4.4.11.2 Test failure. If a torsion bar spring fails to pass any control test specified herein,
this shall be cause for retest of two. Failure of either of the springs to pass the test shall be cause for
the Government Inspector to stop acceptance of subsequent springs until evidence has been provided
by the contractor that corrective action has been taken.
*
4.4.11.3 Endurance test. To determine conformance to 3.2.1, the angular deflection required
shall be as shown on the applicable drawing. The test shall be continuous, constant load test with
automatic or manual compensation for set after 5,000 cycles and every 5,000 cycles thereafter. The
total angle of set during test for particular spring shall not exceed that specified on the drawings.
Rate of loading shall be between ten (10) and one hundred (100) cycles per minute and the
temperature shall not exceed 250F. Anchors used in the testing machine shall be of the same
serration configuration and hardness of those specified for use in operation of the vehicle.
4.5 Inspection of preparation for delivery.
4.5.1 Materials and processing. The Government inspection shall be unscheduled intervals,
inspect all materials and processes involved in the preparation for delivery to determine conformance
to the requirements of Section 5 and specifications referenced therein. Any evidence of deviation
from specified requirements shall be cause for refusal to conduct further inspection until objective
evidence has been provided by the contractor that corrective action has been taken.
