CONFORMITY FOLLOW UP / ASSENT TEST

Conformity test checks the identity of finished products as compared to a reference product present or not.

A variant can be used to conduct Acceptance or Assent tests in the Wine Industry, for example.

These tests are particularly adapted to controls with only 3 to 5 assessors. Decision rules do not rest on classic Gaussian Statistics (or Large Numbers Law), but on a variable consensus test according to the assessor sensitivity.

Panellists must mark on a scale from 0 up to 10 (scale of difference: 0 for no difference, and 10 for a strong difference) the product samples are compared to a standard or reference product present or not. In Acceptance/Assent test, the rule is inverse, that’s means 10 for an excellent product / accepted, and 0 for a bad quality product / rejected.

Two cases can be possible:

If all the experts are rating the product at a lower value than the sensitive threshold (this one can fluctuate, depending of the conformity sensitivity of the panel), the product is accepted.

If one or several experts is(are) rating the product at an higher value than the sensitive threshold, the product is rejected. . Another panel can be asked to confirm or not the rejection decision.

Results after calculation are displayed as below:

Conformity test follow up

It is possible to ask a summary on the acceptation or rejection decisions on a period of time, and, in case of rejection, all the comments related to this decision are displayed automatically.
