TS ISO 2859-1/Cor 1

TS ISO 2859-1/Cor 1 is the technical corrigendum to ISO 2859-1 on sampling schemes indexed by acceptance quality limit (AQL) for inspection by attributes. A corrigendum is intended to correct errors or inconsistencies in the published text rather than to redefine the core method. In lot-by-lot inspection, the basic idea is to make an acceptance decision about a whole lot from a sample taken from that lot, using AQL as a common statistical reference point.

How AQL-based sampling is used

Inspection by attributes deals with classified outcomes such as pass/fail, present/absent, or defective/non-defective rather than measured values. In this context, AQL identifies the quality level for which a sampling plan is intended. The plan supports consistent acceptance decisions for lots by evaluating a representative sample instead of every unit, which is why it is widely used when many similar items must be checked under repeatable conditions.

What this corrigendum means in practice

This listing should be understood as a correction to the existing standard, not as a standalone replacement of the base method. It preserves the underlying framework of the sampling procedures while addressing text-level issues in the published document. In practical terms, such corrections help reduce misreading of terms, symbols, or references without changing the general purpose of the standard.
