Full title and description

ISO 10576:2022 — Statistical methods — Guidelines for the evaluation of conformity with specified requirements. This International Standard provides guidance for making conformity decisions for quantifiable characteristics by combining test or measurement results with their associated measurement uncertainty.

Abstract

This document sets out guidelines for checking conformity with quantifiable characteristics using the test or measurement result together with its associated measurement uncertainty. It is applicable whenever uncertainty can be quantified according to the principles of ISO/IEC Guide 98‑3 (the GUM). The document does not specify actions to take when a conformity test yields an inconclusive result; examples of entities and quantifiable characteristics are provided in an informative annex (Table A.1).

Scope

Provides guidelines to evaluate conformity with specified, quantifiable requirements by combining measurement or test results with their estimated measurement uncertainty. It applies whenever the measurement uncertainty can be expressed using the framework given in ISO/IEC Guide 98‑3 (GUM), and covers uncertainty contributions including those due to sampling. The document is general in nature and imposes no limitation on the type of entity or characteristic subject to conformity assessment; it does not prescribe decision actions for inconclusive results.

Key topics and requirements

• Guidance on combining measured/test results with their associated measurement uncertainty when assessing conformity.
• Use of the GUM (ISO/IEC Guide 98‑3) principles to quantify uncertainty contributions, including sampling uncertainty.
• Consideration of how uncertainty affects pass/fail decisions and the interpretation of results near specification limits.
• Informative examples (e.g., Table A.1) illustrating entities and quantifiable characteristics to which the guidance can be applied.
• Statement that the standard does not prescribe specific remedial actions for inconclusive conformity outcomes.

Typical use and users

Used by quality and compliance managers, statisticians, metrology and calibration laboratories, conformity assessment bodies, regulators, and technical experts who must make or interpret conformity decisions for quantitative requirements. It helps these users account for measurement uncertainty when deciding whether measured results meet specifications or regulatory limits.

Related standards

Key related documents include ISO/IEC Guide 98‑3 (GUM) on the expression of uncertainty in measurement, ISO/IEC 17025 (competence of testing and calibration laboratories, including requirements for considering uncertainty in conformity statements), ISO 5725 (accuracy — trueness and precision of measurement methods and results), and ISO 9001 (quality management principles where conformity decisions may be required). ISO 10576 replaces the earlier ISO 10576‑1:2003 (withdrawn).

FAQ

Q: What is this standard?

A: An ISO International Standard (ISO 10576:2022) giving guidelines for evaluating conformity with specified, quantifiable requirements by taking into account measurement or test results together with their measurement uncertainty.

Q: What does it cover?

A: It covers methods and guidance for using measured/test results and their associated uncertainties (as defined by GUM principles) to assess whether a characteristic meets specified quantitative requirements. It provides examples and explains applicable uncertainty contributions but does not mandate actions for inconclusive results.

Q: Who typically uses it?

A: Quality managers, metrology and calibration laboratories, conformity assessment bodies, statisticians, regulators, and technical specialists involved in making or interpreting pass/fail or acceptance decisions for quantitative requirements.

Q: Is it current or superseded?

A: ISO 10576:2022 is current (published 5 August 2022) and replaces the earlier ISO 10576‑1:2003, which has been withdrawn.

Q: Is it part of a series?

A: The 2022 publication consolidates guidance previously issued as ISO 10576‑1:2003; it references and relies on the GUM uncertainty framework (ISO/IEC Guide 98‑3) and is intended to be used alongside related standards such as ISO/IEC 17025 and ISO 5725 for laboratory and measurement practice.

Q: What are the key keywords?

A: Conformity assessment, measurement uncertainty, statistical methods, decision rule, GUM, quantitative requirements.
