3.3.1 Test by ultrasonic (UT), magnetic particle (MT), or hydrostatic testing. The Contractor may select either method to satisfy testing requirements.

3.3.2 To hydrostatic test, isolate the air receiver by disconnecting all piping, relief valves, and pressure switches. Install pipe plugs/caps, to prevent backflow into compressors and other system components.

3.3.2.1 After all authorized repairs, hydrostatically test the air receiver using clean fresh water in accordance with SFLC Std Spec 0740, Appendix C and manufacturer’s recommended procedures. In the event a test pressure is not listed on the applicable drawing, test to 1½-times the nominal operating system pressure and hold for five minutes. Ensure zero leakage from or permanent deformation of pressure-containing parts by repairing all leaks, deformations, and discrepancies. Submit a CFR.

3.3.2.2 Instruments and equipment that might be damaged by clean fresh water shall be excluded from hydrostatic pressure test.

3.3.2.3 After testing, drain and thoroughly dry the air receivers with warm air. Dispose of testing fluids in accordance with all applicable Federal, state, and local regulations. Reconnect all disconnected piping and restore system. Renew any disturbed gaskets. Do not drain any fluids, including fresh water, into any space, bilge, or exterior location.

3.4 Contractor’s option for valve renewal. The Contractor may, at no additional cost to the Government, opt to renew valves designated for inspection and testing if preferable for the Contractor. If the Contractor elects to renew valves, the Contractor shall ensure the following:

• New valves are commercial-standard type valves, conforming to the applicable standard listed in Table 1(Valve Standards).

• New valves shall be equivalent (including identical material) to the valve being renewed.
