ISO 24095:2021

Overview

ISO 24095:2021 - "Workplace air - Guidance for the measurement of respirable crystalline silica" - provides comprehensive guidance for measuring respirable crystalline silica (RCS) in workplace air. The standard covers direct on-filter and indirect analysis methods using X‑ray diffraction (XRD) and infrared (IR) techniques, and addresses quality aspects across sampling, analysis, and reporting. The scope explicitly includes the crystalline silica polymorphs and and is intended to ensure results are fit‑for‑purpose for comparison with occupational exposure limit values (OELVs).
