MIL-R-85523A(AS)
4.7.7.5 Underwater test set-up. Underwater testing shall be in accordance with Figure 4.
4.8 Methods of inspection.
4.8.1 Visual examination.
4.8.1.1 Regulators. The regulator shall be examined visually for defects to determine conformance to this specification. Defects shall be defined in accordance with Table IX. The regulator shall pass the requirements specified in
3.6.1.1.
4.8.1.1.1 Dimensions. The regulator selected as a sample unit from the lot, shall be checked dimensionally to determine conformance to the dimensions specified on Drawing 1440AS101.
4.8.1.2 Packaging. Each of the fully prepared shipping containers, containing regulators, selected as a sample unit from the lot, shall be examined to determine that the packaging, packing and marking conform to this specification. Defects shall be defined in accordance with Table X. The packaging shall pass the requirements specified in 3.6.1.2.
4.8.2 Outlet pressures.
4.8.2.1 Dynamic pressure. The regulator shall be connected to an air pressure source to provide inlet pressures as specified in Table II. A
sinusoidal breathing simulator shall be connected to the regulator outlet port as specified in 4.7.7.4. The breathing simulator shall be set to the connections specified in Table II and the regulator outlet pressures shall be recorded in accordance with Figure 3. The regulator shall pass the requirements specified in
3.6.2.1.
4.8.2.2 Steady state pressure.
4.8.2.2.1 Performance. The regulator shall be connected to a pressure
source to provide inlet pressures as indicated in Table III. The regulator shall
be subjected to the inlet pressures, altitudes, and flowrates (see 4.7.7.1)
specified in Table III and the regulator outlet pressures shall be recorded,
without the use of a restrictor. The regulator shall pass the requirements
specified in 3.6.2.2.1.
4.8.2.2.2 Performance sampling. The regulator shall be connected to a pressure source to provide inlet pressures as indicated in Table IV. The regulator shall be subjected to the inlet pressures, altitudes and flowrates (see
4.7.7.1) specified in Table IV and the regulator outlet pressures shall be recorded, without the use of a restrictor. The regulator shall pass the requirements specified in 3.6.2.2.2.
4.8.3 Noise level. The regulator shall be installed as shown in Figure 2. The regulator shall then be subjected to an inlet pressure of 30 psig, with an outlet flow of 100 lpm. The noise level shall be measured (see 4.7.7.3) at the
1/3 octave band center frequencies specified in Table V. The test shall be repeated for an inlet pressure of 80 psig. The regulator shall pass the requirements specified in 3.6.3.
4.8.4 Leakage.
