requirements stated herein, compatible with the weapons system, and must get written authority
from the Safety Authority to deviate from these requirements.
4. VERIFICATION.
4.1. Inspection.
4.1.1. Materials. Inspection and testing of component parts and assemblies shall be
made to determine compliance with 3.3. Where defects, incompatibility or inferior quality is
evident and the Safety Authority deems a material analysis is necessary, the contractor will be
required to submit samples or specimens to the contracting officer for analysis and approval.
4.1.2. Examination of Product. Examination of all products shall be made to determine
if the initiator meets the requirements with respect to workmanship, marking, conformance to
drawings, and for any visible defects.
4.1.2.1. Dimensional Inspection. Each part of a new initiator shall be 100 percent
dimensionally inspected for conformance to the applicable drawing. Should replacement of a
part in the initiator be necessary, the replacement part shall be 100 percent dimensionally,
inspected for conformance to the applicable drawing.
4.1.2.2. Radiographic Inspection. All initiators shall be inspected by radiographic
means as specified in 3.3.12 and plates examined for defects.
4.1.2.3. Leakage. A leak test shall be conducted with a dry gas leak detector of
sufficient sensitivity to ascertain if initiators meet the leak rate requirement of 3.3.14.
4.1.3. Instrumentation. Any suitable instrumentation system may be used e.g.
oscillograph, oscilloscope, digital readout, magnetic tape; transducers used with this system
may be any state of the art type e.g. piezoelectric, strain gage, variable reluctance, capacitive,
potentiometer, etc. However, a five percent system accuracy which includes such factors as
non-linearity, frequency response, temperature effects and resolution etc. shall be required.
Documented calibration records on the system as a whole or individual components shall be
maintained and available for reference.
4.1.4. Safety and Functional Reliability. The number of initiators required to meet the
reliability and confidence level of this specification for go-no-go testing is 298. The Safety
Authority has the prerogative of specifying the test procedures and methods of statistical
analysis which will be used to determine the minimum 50 millisecond all-fire stimuli or the
Safety Authority may accept a procedure proposed by the testing laboratory. Paragraph 6.4
summarizes some of the problems in applying various statistical type analyses.
4.2. Test Conditions. The test conditions are described under the individual tests to
which they apply. Initiators shall be fired in the temperature conditioning cabinet at the
applicable test temperature. If it is not possible to fire in the temperature conditioning cabinet,
the initiator shall be fired as quickly as possible after removal from the cabinet and in no case
shall the elapsed time exceed five minutes. During the performance of the tests of 4.4.1
through 4.4.6 the possibility of an initiator firing exists; therefore safety procedures equivalent
to those taken during the destructive tests shall be followed. All functional tests of initiators
are to be performed with the equipment mounted and loaded in a manner to simulate as closely
