Results of a durability ring test

Summary

In 2011, 73 French companies funded a durability ring test that grouped a total of 74 durability testers, making it possible to compare the results from each appliance against the results obtained by Tecaliman appliances, and against those of similar appliances surveyed in this study. The repeatabilities and discriminating power of each appliance were calculated by comparing the measurements obtained from a panel of 5 pellet samples with known durabilities, fully controlled by Tecaliman. This data sheet describes the operating procedure, together with the findings and insights gleaned from this ring test.
