- only when BCM?
- on every test, even TC?
- with the same live sample?
- with a fresh sample?
- Same sample/dummies in clean shakers? cans? different device?
- Single set?
- Single session?
Is there value in changing the testing equipment within a single test?
- Change shakers? cans?
- daily? between sessions?
There are two things at play during all of our resting
- Sample viability
- Test validity
Testing equipment should contain 2 sets each of both cans and shakers.
Syn re-do clothing test; clean equipment, same sample.
