Overview
ISO 80000-4:2019/Amd 1:2025 is the first amendment to Part 4 of the ISO 80000 series, which addresses quantities and units in mechanics. Published by the International Organization for Standardization (ISO), this amendment updates definitions, symbols, and references in the domain of mechanical quantities and units. It aligns Part 4 with the latest International System of Units (SI) and related normative documents to ensure consistency and clarity in technical communication worldwide.
As an integral part of the ISO 80000 series, this amendment enhances the accuracy and interoperability of mechanical measurements by refining terminology and referencing key standards such as the 9th edition of the SI Brochure by the Bureau International des Poids et Mesures (BIPM).
Key Topics
Updated Normative References
The amendment introduces normative references, notably the 9th edition of the International System of Units (SI) published in 2019 by BIPM. This ensures that the mechanical quantities and units conform to the most recent internationally agreed standards.Refined Terms and Definitions
Terms, symbols, and definitions for mechanical quantities are clarified and updated. The amendment emphasizes that all such quantities follow the definitions presented in Table 1 of the standard and in the SI Brochure. This provides a unified framework for consistent usage.Mechanics Quantities & Units Clarification
The document outlines precise definitions for fundamental mechanical quantities like force, mass, acceleration, torque, and energy, along with their corresponding SI units and symbols.Editorial and Compliance Instructions
It adheres to ISO/IEC editorial procedures and the directives for international standard development, ensuring transparency, accessibility, and compliance with established processes.
Applications
Engineering and Manufacturing
ISO 80000-4:2019/Amd 1:2025 supports engineers and manufacturers by providing standardized quantities and units necessary for designing, testing, and producing mechanical systems. Accurate unit definitions prevent miscommunication and errors in specifications, calculations, and documentation.Scientific Research
Researchers working with mechanical phenomena rely on this amendment to maintain uniformity in experimental data reporting and interpretation, fostering reproducibility and data integration across studies and international collaborations.Education and Training
Academic institutions and training centers benefit from an updated canonical source for teaching mechanics units and quantities, ensuring learners understand and apply internationally recognized standards.Quality Assurance and Compliance
Organizations adopt this amendment to align with global best practices in quality management, regulatory compliance, and technical reporting, minimizing risks related to measurement inconsistencies.
Related Standards
The amendment complements and references several key international standards and documents critical for a comprehensive understanding of quantities and units in mechanics:
ISO 80000 Series
This document is part of the broader ISO 80000 series on quantities and units, each part covering various scientific and engineering disciplines.The International System of Units (SI), 9th Edition (2019)
Published by BIPM, this SI Brochure is the authoritative source for unit definitions and conventions internationally.IEC/TC 25 - Quantities and Units
Collaboration with the International Electrotechnical Commission (IEC) ensures synergy in electrical and mechanical units and terminology.ISO/IEC Directives, Parts 1 and 2
These provide the procedural framework for the development, editorial style, and maintenance of ISO standards.
By aligning with these standards, ISO 80000-4:2019/Amd 1:2025 facilitates interoperability and consistency in technical fields involving mechanics worldwide.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
