The standard is highly relevant for laboratories, regulatory authorities, manufacturers using natural mineral fillers, demolition companies, occupational hygienists, and any organization required to demonstrate compliance with asbestos-free claims or threshold regulations.

Key updates include clarifications to detection and quantification techniques—such as polarized light microscopy (PLM), scanning and transmission electron microscopy (SEM/TEM), and innovative sample pre-treatments for organic and mineral matrices. This revision emphasizes method validation, error mitigation, and comprehensive reporting aligned with evolving global norms.

Key highlights:

• Reliable quantification of low-level asbestos (<5% by mass) in challenging matrices
• Detailed procedures for floor tiles, plasters, vermiculite, talc-based, and organic-bound samples
• Enhanced methodologies for regulatory compliance and robust reporting

With climate change introducing unpredictable hazards to workplaces worldwide, ISO/PAS 45007:2026 delivers essential guidance for integrating climate-driven risk factors into occupational health and safety (OH&S) management systems. The document provides a pragmatic framework for identifying, evaluating, and managing both direct and indirect OH&S risks resulting from climate change as well as the adaptations and mitigations required by new environmental policies.

Applicable to organizations of all sizes—ranging from SMEs to multinational corporations—this standard walks users through a systemic, Plan-Do-Check-Act (PDCA)-based approach. Covered topics include risk assessments for extreme weather events, evolving legal requirements, and the operational challenges of changing work methods, supply chain continuity, and infrastructure resilience.

Organizations are encouraged to map both traditional hazards and emerging risks (such as heat stress, supply disruptions, or increased vulnerability of certain worker populations) with climate change adaptation or sustainability initiatives. Opportunities for improvement and resilience building are also emphasized.

Key highlights:

• OH&S frameworks that address climate change impacts and mitigation/adaptation actions
• Step-by-step integration with existing ISO 45001-based management systems

prEN ISO 16094-3 – Thermo-Analytical Detection of Microplastics in Drinking Water

Water Quality – Analysis of Microplastic in Water – Part 3: Thermo-Analytical Methods for Waters with Low Content of Suspended Solids Including Drinking Water (ISO/DIS 16094-3:2024)

Microplastic contamination in water is an urgent global concern, but reliable, standardized analytical procedures have lagged behind the rapid growth in attention. prEN ISO 16094-3 closes this methodological gap by setting best-practice protocols for identifying and quantifying a spectrum of polymer types in water samples with low suspended solids—including potable water.

Focused on thermo-analytical techniques, such as thermal extraction-desorption GC/MS (TED-GC-MS) and pyrolysis-GC/MS (Py-GC-MS), the standard details protocols for sample preparation, polymer detection, quantification, and robust quality controls. It encompasses major polymers—polyethylene, polypropylene, polystyrene, PET, and others—often found in environmental and industrial contexts.

Analytical laboratories, regulatory agencies, municipal water suppliers, industrial water managers, and researchers will all find this standard indispensable for rigorous, harmonized microplastic assessments. Laboratories must ensure suitably qualified staff conduct the testing per the guidelines due to technical complexity.

Key highlights:

• Standardized GC-MS-based protocols for microplastic detection in low-TSS waters
• Applicable to routine analysis of drinking water and environmental monitoring
• Comprehensive provisions for sample integrity, QA/QC, and reporting
