designated by the procuring activity. Film interpretation of the radiographs shall verify the presence and
correct positioning of the following:
a. Presence of ignition device charge
b. No material defects
4.6.6.2 Retainer and ignition device assembly, Drawing 11738409. All retainer and ignition
device assemblies shall be radiographically examined in accordance with ASTM E1742, with the exception
that a retainer and ignition device assembly shall be used for the penetrameter. Any observable
imperfections in components or assembly shall be cause for rejection. The retainer and ignition device
assemblies 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 retainer and ignition device assemblies 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-rays. The retainer and ignition device assemblies 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 be
submitted to the activity conducting the production lot acceptance tests. Defective units 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. Any assembling of the retainer and ignition device assembly into initiators prior to
notification by the contracting agency of X-ray acceptance for the retainer and ignition device assembly
shall be at the contractor's risk. Film interpretation of the radiographs shall verify the presence and
correct positioning of the following:
a. Ignition device charge present and not cracked
b. Anvil present, seated, and not cocked
c. No material defects
4.6.6.3 Initiator assembly, Drawing 11731494. All assembled initiators shall be radiographically
examined in accordance with ASTM E1742, with the exception that an initiator assembly will be used for
the penetrameter. Any observable imperfections in components or assembly shall be cause for rejection.
The initiators 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 initiators shall be identified with serial numbers prior
to X-ray examination. The serial numbers shall be in consecutive order beginning with the number 001 in
each production lot. Any missing numbers are to be identified on the X-rays. The initiators shall be
arranged on trays or boards in consecutive numerical order, and each radiograph shall carry a permanent
identification of the units displayed thereon. The radiographic plate identification shall include item
nomenclature, the complete lot number, the span of serial numbers displayed, and the contract number.
The radiographs of the entire production lot shall accompany the ballistic sample to the activity conducting
the production lot acceptance test. Defective initiators 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:
a.
Ignition device retainer, P/N 11738408
b.
Ignition device, P/N 851AS110
c.
M104 Assembly, P/N 10551446
