Bias and linearity should been done on all measurement devices as part of your calibration program.
Stability studies should be identified by performing a risk assessment to determine whether there is a risk of the device being impacted by environmental conditions or by warmup (e.g., uncontrolled environment, measuring tight tolerances of a product with a high coefficient of thermal expansion).
R&R studies are typically required for any device on your control plan (e.g., used for inspection or process control).
