Detailed Standards Coverage

EN 15051-2:2025 - Workplace Exposure: Rotating Drum Method for Dustiness Measurement

Workplace exposure - Measurement of the dustiness of bulk materials - Part 2: Rotating drum method

Respirable dust generation in industrial processes is a primary occupational hazard. EN 15051-2:2025 delivers a rigorous, reproducible method for measuring the dustiness of powdered, granular, or pelletized bulk materials using a rotating drum apparatus. This test repeatedly drops the material within a controlled drum, simulating real-world handling and providing quantitative categorization of inhalable, thoracic, and respirable dust fractions.

The standard details:

• Equipment design: 300 mm stainless steel rotating drum with precise control of environmental conditions (50 ± 5% RH, 21 ± 3°C)
• Three-stage dust sampling (foam and filter stages for particle size selection)
• Requirements for material conditioning and sample handling
• Categorization scheme for dust emission to inform product selection and risk assessment

Targeted at manufacturers, occupational hygienists, industrial managers, and safety engineers, the standard ensures consistency for workplace exposure assessments and product development across sectors—especially where powder or granular bulk is handled.

Key highlights:

• Harmonized dustiness categories and reporting for cross-site comparability
• Updated procedures for environmental control, analytical precision, and quality assurance
• Major revision: tighter humidity tolerance, increased repeatability, and new categorization limits

ISO/TS 11665-13:2025 - Radon Diffusion in Waterproof Materials

Measurement of radioactivity in the environment - Air: radon 222 - Part 13: Determination of the diffusion coefficient in waterproof materials: membrane two-side activity concentration test method

Radon control in buildings is integral to health protection, particularly in regions with high natural radioactivity. ISO/TS 11665-13:2025 specifies methods for measuring the diffusion coefficient of radon gas through bitumen or polymer membranes and waterproof coatings—crucial properties for radon-proof insulation used in construction. The standard provides both non-stationary and stationary test methods, guidance on system configuration, and requirements for reliable measurement (including source/receiver containers, calibration, and uncertainty estimation).

The specification targets:

• Testing laboratories and construction material manufacturers
• Building code authorities
• Environmental consultants in construction safety

By quantifying how well building materials block radon gas, this standard enables the selection of effective barriers, supports compliance with national building regulations, and improves indoor air quality.

Key highlights:

• Four validated methods (A–D) for accurate radon diffusion determination
• Emphasis on sample preparation, boundary conditions, and radon-tightness checks
• New procedures for minimum decisive measurement duration and data interpretation

ISO 18227:2025 - XRF Determination of Elemental Composition in Environmental Matrices

Environmental solid matrices - Determination of elemental composition by X-ray fluorescence spectrometry

Precise elemental analysis underpins environmental monitoring, waste characterization, and soil management. ISO 18227:2025 standardizes the use of energy dispersive (EDXRF) and wavelength dispersive (WDXRF) X-ray fluorescence spectrometry for quantifying trace and major element concentrations in solid wastes, soils, sludges, and similar materials.

Notable features include:

• Full quantitative procedure based on matrix-matched calibration
• Optional semi-quantitative screening for diverse materials via matrix-independent calibration
• Safety and sample handling guidelines for hazardous materials (waste, sludge)
• Applicability for over 40 elements, with detection from 0.0001% up to 100% by mass, depending on the instrument and material

Intended for environmental laboratories, regulatory agencies, and remediation consultants, the standard enables quality-assured environmental assessments, waste acceptance, and compliance with heavy metal and trace contaminant regulations.

Key highlights:

• Harmonized calibration and analytical procedures for both EDXRF and WDXRF
• Comprehensive safety protocols for sample preparation and analysis
• Inclusion of semi-quantitative screening to broaden practical utility

ISO/TR 8234:2025 - Pre-crash Classification Systems for Road Vehicles

Road vehicles - Pre-crash classification systems

The evolution of automotive safety is driven by a deep understanding of crash precursors and conflict scenarios. ISO/TR 8234:2025 comprehensively documents pre-crash classification systems used to define and analyze interactions between traffic actors that can lead to real-world vehicle accidents. Drawing from global data sets and methodologies (Europe, Japan, USA, China, etc.), this report informs development of active safety tech, road safety research, and vehicle safety assessments.

The standard features:

• Definitions and taxonomies for pre-crash and near-crash events
• Multiple classification systems, focusing on scenario abstraction, actor roles, and conflict characteristics
• Comparative analysis—supporting harmonized safety technology and regulatory frameworks
• Applications for manufacturers, researchers, assessment bodies, and policymakers involved in automotive and transport safety
