TS ISO 2859-1/Amd 1

TS ISO 2859-1/Amd 1 is an amendment to the ISO 2859-1 standard for acceptance sampling by attributes. It points to the updated version of the family of sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot inspection, rather than restating the full base standard on its own. In practical terms, the subject is the statistical decision process used to decide whether a production lot is accepted or rejected based on the results of sampled items.

What acceptance sampling by attributes means

Inspection by attributes classifies items into outcomes such as conforming/nonconforming, pass/fail, or defect present/absent, instead of relying on measured numerical values. The AQL concept identifies the quality level associated with the sampling plan and provides a common statistical reference between producer and inspector. These plans evaluate the sample as a representation of the lot, balancing inspection effort against decision confidence.

Why the amendment matters

As an amendment document, this listing indicates that the parent standard has been revised in specific respects while retaining its overall subject and structure. Users therefore understand the core lot-by-lot acceptance sampling logic and AQL-based indexing from the base standard, with the amendment representing the updated textual edition. Concepts such as lot size, sample size, and accept/reject decision rules remain central to understanding how this standard family is used in quality control practice.

• An acceptance sampling approach based on attribute classification rather than numerical measurement.
• Covers sampling schemes intended for lot-by-lot evaluation.
• AQL is the key concept used to index the plans by an accepted quality level.
• This record is an amendment: it updates the parent standard rather than independently redefining the whole method.
