Using MSA for Situations Requiring Destructive Testing

See how to:

Address key assumptions for MSA (Parts do not change form over time and are not changed by measuring them)
Overcome inability to repeat measurements when key MSA assumptions are violated
Perform and interpret desctructive test that assumes perfect material and likely overestimates part-to-part variation
- Assume material within a lot or a batch is uniform
- Gather multiple lots where each lot represents a part
- Subdivide lots so that each subdivision will represent a repeat measurement when tested
- Test all parts in a random order.
- Analyze using EMP method.
Perform and interpret desctuctive test that assumes perfect test and likely underestimates part-to-part variation
- Use a nondestructive test that correlates well with the destructive test
- Build a calibration curve from destructive and nondestructive test data
- Test parts nondestructively in a random order
- Test parts destructively in a random order
- Use the formula from the calibration curve to scale the nondestructive data
- Combine results
- Analyze using the EMP method

Notes: Questions are included at the end of the demo, beginning at ~ Time 32:30.
