Overview
ISO 80000-9:2019/AMD1:2025 is the first amendment to the International Standard ISO 80000-9, which focuses on quantities and units specifically related to physical chemistry and molecular physics. Published by the International Electrotechnical Commission (IEC) in collaboration with the International Organization for Standardization (ISO), this document updates and refines the standard definitions, symbols, and units required for precision in scientific measurement fields. This amendment enhances clarity and alignment with the International System of Units (SI), supporting consistent use worldwide.
Key Topics
Updated Normative References: The amendment introduces important references, including the ninth edition of the BIPM International System of Units (SI) published in 2019. This ensures the document is aligned with the most current standards and requirements.
Terms and Definitions: The document revises the descriptions of terms and definitions for quantities used in physical chemistry and molecular physics. It specifies that names, symbols, and units adhere to both Table 1 of the standard and the SI, enhancing uniformity and reducing ambiguity.
Standardization of Units: This amendment strengthens the standardization of measurement units relevant to molecular physics and physical chemistry, encouraging global consistency in research, development, and industrial applications.
Collaborative Development: ISO/TC 12 and IEC/TC 25, the technical committees involved, along with CEN, ensure the standards reflect comprehensive expertise and international consensus.
Applications
Scientific Research: This amendment is essential for researchers in physical chemistry and molecular physics, guaranteeing consistent measurement units and definitions in experimental work and publications.
Education and Academia: Universities and educational institutions benefit from precise, standardized quantities and units for teaching advanced concepts in molecular physics and physical chemistry.
Industrial Measurement and Calibration: Industries such as pharmaceuticals, chemical manufacturing, and materials science utilize these standards for accurate measurement systems, quality control, and product development.
International Collaboration: Facilitates coherent communication and data sharing between international scientific communities by providing universally accepted terminology and units.
Related Standards
ISO 80000 Series: A comprehensive series covering quantities and units across various scientific and engineering disciplines, ensuring interdisciplinary consistency.
BIPM International System of Units (SI), 9th Edition (2019): The foundational reference for unit definitions and usage in this amendment.
IEC/TC 25 Standards: Complementary electrotechnical standards developed alongside ISO for quantities and units, ensuring consistency across different technical domains.
Practical Value
The ISO 80000-9:2019/AMD1:2025 amendment is crucial for professionals requiring precise and consistent definitions in physical chemistry and molecular physics. By updating normative references and clarifying units and terminology, it supports accurate experimentation, reporting, and regulatory compliance. Its adoption enhances international standardization, reducing errors and improving interoperability of scientific data.

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).
