The tensile tests are industry standards for testing crimped connectors. UL has a spec as does the US Military, NASA, SAE and even the ABYC.
The military for example has a minimum tensile load rating per wire size. Then they salt
chamber test and vibration test the crimps and test again to make sure they still meet the requirement. Solid gas tight crimps should be unaffected to the minimum tensile rating after salt
chamber and vibration testing.
Different specs have different tensile ratings. For example:
UL 486A for 12GA wire is 70 Pounds
Mil-T-7928 for 12GA wire is 110 Pounds
ABYC E-11 for 12GA wire is 35 Pounds
