4.7.5 Proof pressure (see 3.5.5). The hose assemblies, consisting of lengths of hose with attached

fittings, when subjected to proof pressure testing in accordance with ASTM D380 shall meet the

requirements of 3.5.5. The following details shall apply:

a. Proof pressure shall be specified in table I.

b. Test fluid shall be water or hydraulic fluid in accordance with MIL-PRF-5606, MIL-PRF-87257,

or MIL-PRF-83282.

4.7.6 Elongation or contraction (see 3.5.6). Hoses, when subjected to the elongation and contraction

test in accordance with ASTM D380, shall meet the requirements of 3.5.6. The hose assemblies shall

then be pressurized to the applicable operating pressure specified in table I and held for 5 minutes.

4.7.7 Bending and vacuum (see 3.5.7). Hose assemblies, when subjected to bending and vacuum,

shall meet the requirements of 3.5.7. The following details shall apply:

a. The bending and vacuum test shall be performed at room temperature.

b. A steel ball of the applicable diameter, as specified in table IX, shall be installed within the

hose assemblies.

c. The assemblies shall then be bent over to form the applicable minimum bend radius specified in

table X.
