Scope and purpose

This standard defines a generic attribute skip-lot sampling program. The purpose of this publication is to provide procedures, for reducing the inspection effort on products submitted by those suppliers who have demonstrated their ability to control, in an effective manner, all facets of quality and who consistently produce lots which meet requirements. Inspection may take place at the supplier's or purchaser's locations or at an interface between operations of a production process. The skip-lot procedures are designed to be used with the attribute lot-by-lot plans described in ANSI/ASQ Z1.4.

The skip-lot program described in this standard is based on papers by Liebesman shown in section 2.0. Skip-Lot sampling was originally developed by Dodge. For a discussion of the Dodge plans, see references Dodge (1955), Dodge and Perry (1971), Schilling (1982), and Stephens (2001) cited in the Bibliography.
