Minimal intervention, reversibility and repeatability of preferred treatment are essential, as well as the possibility of easy identification of restored parts.
en.wikipedia.org However, to improve repeatability, they are generally performed on a roller test bench.
en.wikipedia.org The repeatability of this test method was extensively documented.
en.wikipedia.org Common validation characteristics include: accuracy, precision (repeatability and intermediate precision), specificity, detection limit, quantitation limit, linearity, range, and robustness.
en.wikipedia.org Such precise repeatability is required for multiple exposures, traveling mattes, title superimposition, and a range of other techniques.
