General Information

Overview
EN ISO 80000-10:2019/A1:2025 is Amendment 1 to Part 10 of the ISO 80000 series: Quantities and units - Atomic and nuclear physics. Prepared by ISO/TC 12 in collaboration with CEN, this amendment updates the original 2019 document to clarify normative references and the presentation of names, symbols, definitions and units for quantities used in atomic and nuclear physics. The amendment was approved by CEN (5 December 2024) and adopted as a European standard for national implementation by February 2026.
Key topics and requirements
- Normative references updated: Clause 2 now explicitly refers to the BIPM publication The International System of Units (SI), 9th edition (2019) as a normative reference. This ties the atomic and nuclear quantities directly to the current SI rules.
- Terms and definitions clarified: Clause 3 is modified so that names, symbols, definitions and units for relevant quantities are provided in Table 1 and follow the SI. This formalizes how atomic and nuclear quantities should be named and represented.
- Scope of amendment: The amendment modifies EN ISO 80000-10:2019 without other technical changes and is published in English, French and German; translated national versions are allowed.
- Standards governance: CEN endorsement means national standards bodies in CEN member countries must adopt the amendment (publication or endorsement) and withdraw conflicting national standards by the specified deadline.
- Implementation note: The document draws attention to potential patent issues and advises implementers to consult the ISO patent database.
Practical applications and users
This amendment supports consistent, interoperable use of quantities and units in disciplines and activities such as:
- Scientific research in atomic, nuclear and particle physics
- Calibration and measurement in national metrology institutes and labs
- Instrumentation and detector manufacturers for nuclear-related equipment
- Software developers and data modelers encoding physical quantities (simulation, data exchange)
- Technical publishers, educators and standards writers ensuring consistent notation
- Regulatory agencies and test laboratories that require SI-consistent reporting
Users benefit from harmonized symbols, definitions and SI-based units, reducing ambiguity in measurement, data exchange and technical documentation.
