Assembly and Leak Check Fit, function, and integrity of the manufactured hardware shall be verified by assembling the components as defined in drawing MER03126 and performing a leak check with water as described here. All MER03126 assembly items not specifically identified in the Manufacture section above but necessary for the leak check shall be provided by MSFC upon request.

Verification #1 ‐ Visible Leak Inspection:

The assembly shall be supported, filled with potable water, purged of trapped gas, and subjected to a continuous pressure of between 725 and 735 pounds per square inch (gauge).

The source of all visible water leaks shall be identified and corrected before proceeding to the second verification.

Verification #2 – Pressure versus Time:

The assembly shall be supported, filled with water, and purged of trapped gas. The assembly shall be pressurized to between 725 and 735 pounds per square inch (gauge) and isolated from the pressure source. The difference in initial and final internal pressures after 10 minutes of isolation shall not exceed 5 psi.

Deliverables The following items and quantities shall be delivered to MSFC at the end of the period of performance:
