Mechanical Impact for Materials in Variable Pressure GOX andLOX

Test 13b from NASA-STD-6001

• Purpose: Determine if materials in oxygen environments react when mechanically impacted

• This test covers high pressure and high temperature GOX environments, as well as LOX systems

Mechanical Impact for Materials in Variable Pressure GOX and LOX

Test 13b from NASA-STD-6001

• Typical Specimen– Liquids and solids at

minimum use thickness• Test Conditions

– LOX and GOX – Worst case temperature and

pressure• Acceptance Criteria

– 20 samples must not react when impacted at 98 J

– If one sample reacts, 40 more must be tested without reactions to pass
