Test methods and procedures.



MIL-R-82689
4.5.3 Inspection testing. The following tests shall be performed in accordance with 4.6.
4.5.3.1 Hardness. Fifty units from each heat treated lot of components shall be tested for compliance
with the requirements on the applicable drawing.  Failure of any unit to comply with the drawing
requirements shall be cause for rejection of the lot of components.
4.5.3.2 Hydrostatic pressure. Each cylinder and housing shall be subjected to the internal hydrostatic
pressure test. Failure of any unit to comply with 3.4 shall be cause for rejection.
4.5.3.3 Protective finish. Each batch of plated hardware shall be tested in accordance with the
applicable specification.  Failure of any sample to comply with the requirements of the applicable
specification shall be cause for rejection of the lot.
4.5.3.4 Residual magnetism. Each assembly shall be subjected to the test for excessive residual
magnetism as specified in 4.6.4. Failure of any unit in the inspection sample to comply with 3.10 shall be
cause for rejection of the lot.
4.5.3.5 Static load. Each rod and piston subassembly shall be subjected to an axial static load test as
specified on the appropriate drawing. Any failure to comply with the requirements shall be cause for
rejection of the subassembly.
4.5.3.6 Metal parts assembly. Each firing pin release assembly, except for the dust seal, shall be
subjected to tests as specified in 3.7. Failure of any assembly to comply with the requirements of 3.7 shall
be cause for rejection of the assembly.
4.5.3.7  Radiographic inspection.  All assembled release mechanisms shall be radiographically
examined in accordance with MIL-STD-453. Any observable imperfection in components or assembly shall
be cause for rejection of that unit. The release shall be positioned for the most revealing exposure with the
long axis of each assembly perpendicular to the rays of the X-ray machine. All releases shall be identified
with serial numbers prior to X-ray examination. The serial numbers shall be in consecutive numerical order
beginning with the number (001) in each production lot. Any missing serial numbers are to be identified on
the X-ray plates. The releases shall be arranged on boards or trays in consecutive order and each radiograph
shall carry a permanent identification of the units displayed thereon. The radiographic identification shall
include item nomenclature, the complete lot number assigned to that lot and the span of serial numbers
displayed. Radiographs of the entire production lot shall accompany the ballistic sample to the activity
conducting the production lot acceptance tests. Defective releases found during X-ray review are to be
marked on the x-ray prior to shipment and those defective items shall be removed from the production lot.
Film interpretation of the radiographs shall verify the presence and correct positioning of the following parts:
(1)
Cylinder
(2)
Housing
(3)
Piston, Unlocking
(4)
Sleeve, Retaining
(5)
Rod and piston assembly
(6)
