MIL-DTL-62547D
4.2.1 Sampling. Sampling shall be as specified in the contract or order (see 6.2).
4.2.2 Examination. Each valve and extinguisher selected in accordance with 4.2.1 shall
be subjected to the examinations specified in table IV. Failure of any examination shall be cause
for rejection.
4.2.3 Tests. Each valve and extinguisher shall be subjected to the tests specified in table
IV. Failure of any test shall be cause for rejection.
4.3 Verification methods. Acceptable verification methods included in this section are
visual inspection, measurement, sample tests, full-scale demonstration tests, simulation,
modeling, engineering evaluation, component properties analysis, and similarity to previously-
approved or previously-qualified designs.
4.3.1 Verification alternatives. The manufacturer may propose alternative test methods,
techniques, or equipment, including the application of statistical process control, tool control, or
cost effective sampling procedures to verify performance. See the contract for alternatives that
replace verification methods required by this specification (see 6.2).
4.3.2 Verification conditions. Unless otherwise specified (see 6.2), all inspections shall
be conducted under the following conditions:
a. Air temperature: 23±10 °C (73±18 °F)
b. Barometric pressure: 96.66 (+6.67, -10) kPa (28.5 (+2, -3) in. of mercury)
c. Relative humidity: 50±30%
4.3.2.1 Voltage setting. For all tests, the input voltage shall be supplied by batteries
(16 to 30 V dc), or a variable power supply of 30 A minimum current capacity, as specified
herein or as appropriate.
