Overview

ISO 2859-1:1999/Amd 1:2011 is an important amendment to the international standard for sampling procedures for inspection by attributes. This standard, titled Part 1: Sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot inspection, provides updated guidance and detailed protocols for statistical quality control using acceptance quality limits. Published by ISO, the amendment enhances the original 1999 standard by incorporating the roles of switching rules and aligning references with updated related standards.

The standard is maintained by ISO Technical Committee ISO/TC 69, Subcommittee SC 5, focusing on the application of statistical methods to acceptance sampling. It plays a vital role in improving quality assurance processes across various industries by standardizing sampling plans for lot inspections and ensuring consistent product quality control.

Key Topics

• Sampling by Attributes: Procedures that rely on qualitative inspection results (acceptable or non-acceptable) rather than measurements.
• Acceptance Quality Limit (AQL): The maximum percentage of defective items considered acceptable during random sampling inspection.
• Lot-by-Lot Inspection: Evaluation of production lots one at a time based on selected sampling plans.
• Switching Rules: Updated rules incorporated through Amendment 1 that govern when to change sampling levels based on inspection history.
• Normative References: Integration of related ISO standards such as ISO 2859-3 (skip-lot sampling), ISO 3534-1 and ISO 3534-2 (statistical terminology and applied statistics), and ISO 24153 (randomization procedures).
• Updated Tables and Graphical Adjustments: Corrections and clarifications to acceptance criteria graphs and scoring methods.
• Recommended Use with ISO 2859-10: Suggested complementary guidance on the introduction and application examples for the ISO 2859 series.

Applications

ISO 2859-1:1999/Amd 1:2011 is widely employed for quality control and acceptance sampling in manufacturing, production management, and supply chain inspections. Practical applications include:

• Manufacturing Quality Assurance: Ensuring products meet specified AQLs before releasing lots to customers.
• Supplier and Incoming Goods Inspection: Lot-by-lot sampling to verify compliance without inspecting every item.
• Statistical Process Control: Integrating acceptance sampling plans to detect changes in process quality.
• Regulatory Compliance: Meeting international or industry-specific quality requirements through standardized sampling.
• Risk Management: Reducing inspection costs and efforts without compromising the detection of defective lots.

Organizations in sectors such as automotive, electronics, pharmaceuticals, and consumer goods benefit from applying these statistical sampling schemes to monitor quality and reduce the likelihood of defective products reaching the market.

Related Standards

For comprehensive quality control using attribute-based sampling, the following related ISO standards complement ISO 2859-1:1999/Amd 1:2011:

• ISO 2859-10: Introduction to the ISO 2859 series with illustrative examples to facilitate implementation.
• ISO 2859-2: Sampling plans indexed by Limited Quality (LQ) for isolated lot inspection.
• ISO 2859-3: Skip-lot sampling procedures for selectively inspecting lots based on quality history.
• ISO 3951 (all parts): Sampling procedures for inspection by variables, focused on measured data.
• ISO 24153: Guidelines for random sampling and randomization procedures that ensure sample representativeness.
• ISO 3534-1 and ISO 3534-2: Definitions and vocabulary for statistical terms used within the sampling standards.

Using these standards in conjunction ensures a robust, statistically sound approach to quality inspection aligned with international best practices.

---

By adhering to ISO 2859-1:1999/Amd 1:2011, organizations can optimize their inspection processes with statistically validated sampling plans, maintain consistent product quality, and efficiently manage inspection resources. This amendment reflects current industry needs by refining sampling rules and references, contributing to the ongoing reliability and relevance of the ISO sampling procedures series.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO 2859-1:1999 was prepared by Technical Committee ISO/TC 69, Applications of
statistical methods, Subcommittee SC 5, Acceptance sampling.

L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
