Full title and description

ISO 2859-1:1999/Amd 1:2011 — Sampling procedures for inspection by attributes — Part 1: Sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot inspection — Amendment 1. This document is an amendment to ISO 2859-1:1999 that provides changes and corrections to the Part 1 sampling schemes and related guidance for AQL‑based, lot‑by‑lot inspection procedures.

Abstract

This amendment (2 pages) updates ISO 2859-1:1999 by modifying elements of the AQL‑indexed sampling schemes and clarifying or correcting editorial and tabular information used to select sample sizes and acceptance numbers for lot‑by‑lot attribute inspection. It is a short, technical change intended to be used together with the 1999 Part 1 text.

Scope

This amendment applies specifically to ISO 2859-1:1999 (Part 1 of the ISO 2859 series) and makes targeted changes to the sampling schemes and associated information used for attribute inspection indexed by Acceptance Quality Limit (AQL). It is intended to be read and applied together with the base Part 1 standard; it does not constitute a standalone replacement. The amendment has since been withdrawn and the Part 1 content has been updated in the 2026 edition.

Key topics and requirements

• Amendments to AQL‑indexed sampling schemes (tables and selection rules) used for lot‑by‑lot attribute inspection.
• Corrections and editorial clarifications to the Part 1 text and tabular data.
• Continued reliance on AQL principles for determining sample sizes, acceptance and rejection numbers for inspected lots.
• Intended application alongside ISO 2859-1:1999 procedures rather than as a standalone document.

Typical use and users

Quality engineers, inspection planners, suppliers, buyers, conformity assessment bodies and quality assurance personnel who apply AQL‑based acceptance sampling for lot‑by‑lot inspection. The amendment was used by organizations that had implemented ISO 2859-1:1999 and needed the small technical or editorial updates provided by Amendment 1. With the publication of the consolidated 2026 edition, users are generally directed to the current Part 1 text.

Related standards

ISO 2859 series (other parts of the sampling procedures for inspection by attributes), ISO 2859-1:1999 (base text that this amendment modifies), and subsequent consolidated/revised editions (notably ISO 2859-1:2026 which supersedes the 1999 text and its amendments). Other adjacent standards on statistical quality control and sampling include ISO 3951 (sampling procedures for inspection by variables) and ISO 9001 (quality management systems) where acceptance sampling may be referenced.

Q: What does it cover?

A: It covers targeted updates to the sampling schemes and related tabular or editorial material in ISO 2859‑1:1999; the amendment itself is brief (2 pages) and intended to be used together with the 1999 Part 1 standard.

Q: Who typically uses it?

A: Quality and inspection professionals, procurement and supplier quality personnel, and conformity assessment bodies that implement AQL‑based lot acceptance sampling. It was applicable to organizations using ISO 2859‑1:1999 prior to the release of the consolidated 2026 edition.

Q: Is it current or superseded?

A: The amendment was published in June 2011 but has been withdrawn as the ISO 2859-1 content was revised and republished in a consolidated 2026 edition; users are advised to consult the 2026 Part 1 edition for the current requirements. In some national catalogues the withdrawal became effective on 22 January 2026.
