OQ and PQ checks ought to take into account the geometry on the sample (e.g. shape and dimensions from the container, and length to the sensitive surface area of your detector). Re-qualification policy of dose calibrators need to account that each day checks (e.g. constancy tests) are frequently executed, as well as verification of linearity and re
4). There's a sharp rise in Rp specifically immediately after 17 h of Main drying time. This occurs In spite of everything ice sublimes and resistance gets to be a function of diffusion of unfrozen h2o in the drying reliable. As a result, the point of maximum resistance right before full lack of ice is considered The purpose in the curve just prior
For example, your WPS suggests preheat temperature as a hundred to one hundred sixty degree Fahrenheit. You might be setting up the preheat system on the test specimen and measuring foundation metallic temperature which has a pyrometer and after couple of minutes you history the joint temperature as one hundred forty degree Fahrenheit, and You then
