Low-Pressure Rectangular Vessel for Space - ASME Div 1 App13 OR Div 2-Part4-NonCirc Vessel? 2

[Astronoza]

Low-Pressure Rectangular Pressure Vessel Code for space, what code to choose?

[Technically hermetic enclosure]
ASME BPVC Sect VIII Div 1 Appendix 13
OR
ASME BPVC Sec VIII Div 2 Part 4.12

- Purpose: Hermetically enclosed Astrobio experiments aboard small free-flying satellite vessels.
- Pressure: Design at 2 atm (space launch req) operating at 1 atm for astrobio experiment.
- Volume: 300 mm x 200 mm x 100 mm (6U Cubesat form factor)
- Sealed via top face panel with rectangular hole pattern and o-ring.
- FEA is needed to compare to Numerical Calculations. Stress Linearization first thought.
- Additional dynamic FEA [modal, random, shock] will be carried out for launch.
- Ambient temperature for now

ASME is an allowable code as per usual NASA launch reqs.

Context
Cubesats are presenting a new source for astrobio experiments. This requires a workflow of a hermetic metal enclosure that will undergo dynamic load environments for a launch. Rectangular volumes allow the most accessibility to current proof-of-concept launch opportunities.

Astronoza, given that this is hardware for spaceflight, weight is important, I'd want something less, uh, conservative than Apx 13.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Agree with the above. By the time you carry out all the work above, I don't think trying to comply with a vessel code would add anything to the project.
I'm visualizing the result as a steampunk satellite.
