MIL-PRF-83323C
3.7.1 Reliability. The preproduction tests specified herein are representative of the total life cycle of the tester.
Malfunction or unsatisfactory performance of the tester during preproduction testing shall not be permitted. If
such conditions occur, retesting shall be required. Since any failures or unsatisfactory performance encountered
during the test program may be corrected by retesting with satisfactory results, the total reliability of the tester may
be analytically determined.
3.7.2 Safety inspection. The tester shall be inspected for burrs, nicks, sharp edges, foreign materials, or other
imperfections that pose physical danger to the operator.
3.8 Operating environmental requirements. The tester shall be capable of operation after being subjected to the
following environmental conditions without degradation in performance.
3.8.1 Shock. After severe shock.
3.8.2 Corrosion resistance. After corrosion resistance testing of MIL-F-8615.
3.8.3 Humidity. After 95% relative humidity.
3.8.4 Dust (fine sand). Following exposure to a dust laden atmosphere.
3.8.5 Fungus. When encountering tropical climates and fungi.
3.8.6 Explosive atmosphere. Following explosive atmosphere tests.
3.8.7 Container tests. Tests as specified in paragraph 4.4.13.
4. VERIFICATION.
4.1 Classification of inspections. Inspection requirements specified herein are classified as follows:
a. First article inspection.
b. Conformance inspections.
4.1.1 First article inspection. First article inspection shall be performed on the initial production ready
production-representative units of an order or when required by the contract. When a first article inspection is
required (see 6.2), it includes all verifications listed in para. 4.3.
4.1.2 Conformance inspection. Conformance inspection shall be the following examinations and tests:
a. Examination of product (4.4.1)
b. Functional (4.4.2)
c. Dielectric strength and noise susceptibility (4.4.3)
d. Proof pressure (4.4.4)
e. Fuel leakage (4.4.5)
f. Bonding (4.4.15)
4.2 Test Conditions.
4.2.1 Atmospheric Conditions. Unless otherwise specified, all tests required by this specification shall be
conducted at room temperature between 16and 32C, at a barometric pressure of 28 to 32 inches of mercury, and
at a relative humidity of 80 percent or less. Where tests are substantially different from the above values, proper
allowance shall be made for the change in instrument reading.
