In regards to your questions –
The process and test method are two different things:
- The process of making the test article was performed by a single, qualified operator, using one calibrated piece of equipment set to one temperature and air flow rate. The process monitoring routinely shows distinct categories – goodness knows why…
-
A heat-shrink process at work outputs a trimodal distribution for tensile strength (or a greater number of groups) when parameters such as temperature and operator vary in a single batch, but because the LSL (one-sided specification) is well below the values we see we are meeting quality requirements.
We are now repeating TMV for that test, and…[Read more]
