Overview
EN ISO 80000-8:2020/A1:2025 is the first amendment to the international standard ISO 80000-8:2020, focusing on quantities and units specifically related to acoustics. This amendment, approved by CEN in December 2024 and published in 2025, integrates updates essential for precise and consistent acoustic measurements and noise abatement practices. It aligns with the international system of units (SI) and incorporates the ninth edition of the SI Brochure by BIPM (2019), ensuring up-to-date terminology and standardization.
This standard forms part of the broader ISO 80000 series on quantities and units, serving as a critical reference for professionals working in acoustical engineering, environmental noise assessment, and sound measurement fields across Europe and internationally. The amendment mandates national adoption by CEN member states by February 2026, assisting harmonized application across multiple countries.
Key Topics
