Inertial tolerancing [1]-[3] presents is a statistical expression of a characteristic tolerance without defining the specification interval as is traditionally the case. Conformity is defined by "inertia" (Taguchi loss function [4]) around the target. Although this tolerancing method offers numerous advantages in terms of Quality/Cost ratio, it raises new problems in the customer/supplier relationship. This paper develops an acceptance sampling method design for inertial tolerancing and a sorting strategy when a lot is rejected.
