Paper Abstract

12 In the paper, a new method of flaw evaluation in time for an organized production is presented. A statistical correlation between the number of flows, the degree of gravity, the optimum production volume, the operators qualification level and their testing charge was established. The demerit method is a statistics one based on according a number of points to the defect types as function of their gravity degree. The `demerit' (term derived from French `sans merite') represents a mediation coefficient of the defects frequency pondered according to the assigned points. The `demerit' represents a synthetic complex and complete indicator, related to the defect number as well as to their gravity level.
