TS ISO 2859-1/Amd 1

TS ISO 2859-1/Amd 1 is an amendment to the base standard on sampling procedures for inspection by attributes, focused on acceptance quality limit (AQL) indexed sampling schemes for lot-by-lot inspection. It belongs to the statistical acceptance-sampling family, where decisions about a lot are supported by examining a limited sample rather than inspecting every unit.

What AQL-indexed sampling means

In general technical terms, an AQL-based scheme links the acceptable defect level, sample size, and acceptance number into one controlled decision structure. This makes it possible to apply consistent acceptance criteria when full inspection of every item is impractical or too costly. Inspection by attributes means the result is recorded in categorical terms such as conforming/nonconforming or defective/nondefective, rather than as a measured numerical value.

Where this document is used

The subject matter fits common applications such as incoming inspection, shipment release, supplier acceptance, and other lot-based quality decisions in manufacturing and supply chains. AQL should be understood as a reference point for a sampling plan, not as a blanket guarantee of process capability or long-term product quality. The key technical idea is to balance inspection effort against decision risk in a predefined and repeatable way.

This record is an amendment, so it should be read as a change to ISO 2859-1:1999 rather than as a standalone replacement for the full base standard. Its value lies in updating the established AQL-indexed sampling framework used for attribute inspection of lots.
