specified in the acquisition document (see 6.2). The sample of valves shall be subjected to the
following tests:
a. Temperature regulation (see 4.6.3).
b. Pressure relief (see 4.6.4).
c. Twice the oil cooler proof pressure oil surge (see 4.6.5.2).
4.4 Test conditions. Unless otherwise specified (see 6.2), all inspections shall be performed in
accordance with the following test conditions.
4.4.1 Atmospheric conditions. Tests shall be conducted at standard atmospheric conditions.
4.4.2 Oil. The oil used for all tests shall be specified in the acquisition document (see 6.2).
4.5 Requirements cross-reference matrix. Table I provides a cross-reference matrix of the
section 3 requirements tested or verified in the paragraphs below.
4.6 Tests.
4.6.1 Examination. The valve shall be examined for compliance with requirements for
materials, compatibility, interface, maintainability, identification, interchangeability, and the
presence of foreign materials.
4.6.2 Leakage. The valve shall be submerged in water at 165o +10oF for 1 minute with air
pressure of 85 +15 psi applied to the valve inlet with all other valve openings closed. There shall
be no leakage.

4.6.3 Temperature regulation. In order to isolate the temperature regulation ability of the valve
from any oil pressure relief device effects, the oil pressure at the valve inlet (PA) shall be less
than the oil pressure drop which would start oil flow through the bypass passage. Oil at a
temperature of 45o +2oF shall be circulated through the valve and bypass passage (see figure 1).
The oil temperature shall be increased until oil starts to circulate into the oil cooler. This shall not
