TS ISO 2859-1/Cor 1

TS ISO 2859-1/Cor 1. OFFICIAL SCOPE IS UNAVAILABLE. This record belongs to a corrigendum to the ISO 2859-1 family of sampling procedures for inspection by attributes. The subject is statistical acceptance sampling for lot-by-lot decisions, where products are judged by classified characteristics such as conforming/nonconforming or defective/nondefective rather than by continuous measurement alone.

How AQL-based sampling works

Acceptance quality limit, or AQL, is the indexing concept used to relate a sampling plan to an acceptable level of defects for inspection purposes. In practice, the sample size and the acceptance and rejection numbers are paired so that a lot can be evaluated without inspecting every unit. This is widely used when incoming materials, production lots, or shipments need a fast and consistent decision framework.

Attribute inspection and lot-by-lot decisions

Inspection by attributes means the result is classified rather than measured on a continuous scale. Typical attribute decisions ask whether a unit is defective, whether a requirement is met, or whether a specified feature is present or absent. Lot-by-lot inspection means each shipment or production lot is treated separately, allowing a standardized acceptance decision for each lot.

This listing is a corrigendum, so it should be read together with the parent standard and does not by itself define the full technical requirements. Corrigenda commonly address editorial, terminology, or cross-reference corrections, but no clause-level changes can be stated here because the exact correction is not provided.
