Water Repeatability Method
Texture Technologies developed the water repeatability method in order to compare the performance of one instrument to another, even when the instruments may be at different locations. This method is in response to requests for specific products or materials that can be used dynamically to validate that their instruments are operating effectively. The theoretical material would have to generate extremely repeatable results when tested, be insensitive to aging/oxidation/temperature/altitude, is operator independent, is not subject to developing a history (eg. over-stress bloom strips or test springs), and be available in identical formulations at different locations.
