PRESSURE VESSEL LEVEL LEAK TEST
Each individual pressure vessel must undergo leak testing to demonstrate a maximum leak rate of 10
-6
sccs at MEOP. For pressure vessels that meet material compatibility requirements stated in Section 4.1.5.2, leak testing can be validated using the following method. Documentation must be submitted to SpaceX in order to evaluate conformance. All nonconforming material compatibility pressure vessels must contact their SpaceX representative for special leak test requirements. I. Fully submerge pressure vessel in water II. Pressurize to MEOP III. Test Fluid Helium or 90% Nitrogen Helium mix IV. Minimum Time duration 1 hour V.
Deliverables: Continuous video of full water surface Closeup video of each fitting and connection individually Closeup video of pressure gauge (or data trace) VI. Success Criteria No bubbles Pressure vessel tests must take proper precautions to ensure safety.

US DOT PRESSURE VESSELS
Pressure vessels that are United States Department of Transportation (US DOT) certified and are operated within their published limits and working fluids are strongly preferred over custom vessels. Verification for US DOT pressure vessels A certificate of conformance from vendor stating vessel maximum design pressure (MDP) including any special permits on the bottle design from vendor. A visual of the bottle including the mounting demonstrating amounting scheme that does not induce significant loading into the bottle (i.e. bottle is not a primary load path for anything besides the bottle itself.
