MIL-DTL-19328F
3.7.9.1 Shock (procedure I). The converter, when tested as specified (see 4.6.13.1 and 4.6.13.4) shall show
no evidence of mechanical or material failure and the evaporation loss shall not exceed 2.5 pounds (1.13 kg).
3.7.9.2 Shock (procedure II). The converter, when tested as specified (see 4.6.13.1 and 4.6.13.5), shall not
break free from the mounting provisions.
3.7.10 Salt fog. The converter, when tested as specified (see 4.6.14), shall show no evidence of corrosion or
mechanical failure.
3.7.11 Gunfire. The converter, when tested as specified (see 4.6.15), shall show no evidence of shattering.
The installation mounting base of the converter shall withstand the forces exerted by the gunfire test.
3.7.12 Reliability. The converter, when tested as specified (see 4.6.16), shall have a specified mean time
between failures (MTBF) of not less than 300 hours at the 90 percent lower confidence limit. (This is equivalent
to a minimum acceptable MTBF of 200 hours, and to a reliability of 0.9933 for a 2-hour mission.)
3.7.13 Maintainability. The total corrective maintenance time, when performed as specified (see 4.6.17),
shall not exceed 1 hour of maintenance downtime.
3.7.14 Interchangeability. All parts having the same manufacturer's part number shall be functionally and
dimensionally interchangeable.
3.7.15 Weight. The empty weight of the complete converter, including shock mounts if provided and the
receptacle halves of the quick disconnect couplings, shall not be greater than 15 pounds (6.29 kg).
4. VERIFICATION
4.1 Classification of inspection. The inspection requirements specified herein are classified as follows:
a. Qualification inspection (see 4.2)
b. Conformance inspection (see 4.3)
4.2 Qualification inspection. Qualification inspection shall consist of all the examinations and tests of this
specification.
4.2.1 Qualification samples. Qualification samples shall consist of the following:
a. Two each complete converter assemblies.
b. One each inner vessel complete with all lines and fittings.
c. One each sensing element.
d. One each combination fill-buildup-vent valve.
e. One each relief valve.
f. One each pressure control valve.
g. Three each overpressure safety devices.
h. A Statement of Certification (with supporting test data) from the manufacturer that the converters conform
to the reliability requirements cited (see 3.7.12 and 4.6.16).
