5.0 PROCEDURE

5.1 TEST PREPARATION

5.1.1 Verify that the DIN Valve has been tagged QC acceptable and has been serialized IAW

Reference 2.2.2.

5.1.2 Operate the DIN Valve handle through its full range to verify that it is operating correctly.

5.1.3 If the DIN Valve is not operating correctly or is otherwise unacceptable, abort the test.

5.1.4 Lubricate DIN Valve O-Ring with MIL-PRF-27617 Oxidizer Resistant Grease.

5.1.5 Connect DIN Valve to DIN Valve Adapter or other suitable adapter.

5.2 CLOSED VALVE HYDROSTATIC TEST

5.2.1 Connect the DIN Valve/Adapter to the hydrostatic pump with the appropriate calibrated pressure gauge (Sec. 4.2.2.1) in line. Record DIN Valve serial number and the gauge calibration information on Data Sheet 1.

5.2.2 Close the DIN Valve and flood the system ensuring that all air is vented.

5.2.3 Pressurize the system to 6,000 +50/-0 psig. Record the test pressure on Data Sheet 1.

5.2.4 Hold the pressure for 5 +2/-0 minutes and observe the DIN Valve for leaks. Record the start time on Data Sheet 1.

5.2.5 No leaks are acceptable. If no leaks are present proceed to step 5.2.7. If leaks are detected, continue with step 5.2.6.

5.2.6 Release the pressure, check the system setup, and begin again with step 5.2.1 recording the results of the retest on a Supplemental Data Sheet (Section 7.0). If a leak is detected on the retest, record the results and abort the test.

5.2.7 Release the pressure and drain the water from the DIN Valve. Indicate the results, record the stop and duration times, and complete Data Sheet 1.

5.3 OPEN VALVE TIGHTNESS TEST

5.3.1 Connect the DIN Valve to the clean air supply with the appropriate calibrated pressure gauge (Sec. 4.2.2.2) in line. Record DIN Valve serial number and the gauge calibration information on Data Sheet 2.

5.3.2 Close the DIN Valve, pressurize the system to 4,000 +50/-0 psig, and secure the air supply.

Record the test pressure on Data Sheet 2.

5.3.3 Install a first and second stage diving regulator on the DIN Valve, fully open the DIN Valve and fully immerse the entire assembly in a container of clean water for 5 +1/-0 minuets.

Record the start time on Data Sheet 2.

5.3.4 Observe the water for escaping air. No leaks are acceptable. Record the results on Data

Sheet 2. If no leak is detected, indicate the results and record the stop and duration times on Data Sheet 2. If a leak is detected, record the results on Data Sheet 2and abort the test.

5.3.5 Remove the DIN Valve from the water, vent the air from the hoses, remove the DIN

Valve/Adapter from the test setup and complete the Data Sheet 2.
