ISO 3534-2:2006

Overview

ISO 3534-2:2006 - Statistics - Vocabulary and symbols - Part 2: Applied statistics provides a standardized vocabulary, symbols and abbreviations for applied statistics. Organized thematically with an alphabetical index, the standard sets out clear, low‑mathematics definitions intended to promote consistent terminology across ISO/TC 69 standards and to improve clarity and cohesion in the use of applied statistics in industry, testing and education.

Key topics

The standard covers practical statistical concepts and notation used in applied work, including:

• Data generation and collection: reference value systems, data sources, sampling types.
• Statistical process management: process concepts, variation, control charts and their components, process performance and capability.
• Specifications, measurements and test results: specification concepts, measurement/determination of characteristics, properties of test and measurement methods and results, capability of detection.
• Inspection and acceptance sampling: inspection types, acceptance sampling systems, acceptance criteria, operating characteristic curves and outgoing quality concepts.
• Sampling of bulk materials: bulk sampling concepts, sample preparation and procedural aspects.
• Symbols and abbreviations: normative Annex A lists standardized symbols and shortened terms for applied statistics.
• Methodology: informative Annex B describes how the vocabulary was developed.

Practical applications

ISO 3534-2:2006 is designed for practical, everyday use where consistent statistical language and symbols are essential. Typical applications include:

• Harmonizing terminology across quality management, manufacturing and testing documentation.
• Supporting development and interpretation of control charts, process capability studies and acceptance sampling plans.
• Guiding test laboratories and measurement teams on properties of test methods and reporting of measurement results.
• Informing procurement, supplier quality agreements and contract specifications that reference statistical acceptance criteria.
• Educational and training materials for statisticians, engineers and auditors seeking a consistent, low‑math glossary of applied statistical terms.

Who should use it

• Quality engineers and managers
• Statisticians and data analysts in industry
• Metrology and testing laboratories
• Standards developers (ISO/TC 69 and related committees)
• Technical writers, educators and auditors

Related standards

ISO 3534 is a multi‑part series:

• Part 1: General statistical terms and terms used in probability
• Part 3: Design of experiments

Using ISO 3534-2 together with Parts 1 and 3 helps ensure consistent statistical vocabulary across specifications, process control, sampling and experimental design.
