In today’s fast-evolving workplaces, ensuring healthy air quality and minimizing exposure to hazardous airborne particles is more than just regulatory box-ticking—it’s a core business priority. Three leading international standards—CEN/TS 18086:2024, EN 15051-2:2025, and EN 15051-3:2025—offer robust frameworks for monitoring and controlling workplace atmospheres. From nanomaterial production to broad industrial material handling, adopting these standards drives compliance, productivity, and workforce well-being for organizations of all sizes.
Overview / Introduction
Ensuring a safe and healthy workplace atmosphere is essential for every industry that handles powders, particulates, or nanomaterials. As workplace environments have grown more sophisticated, so too have the risks associated with airborne contaminants—from invisible nano-objects to dust produced while handling bulk materials.
International standards now provide a must-have toolkit for businesses. They offer precise requirements for measuring, monitoring, and communicating airborne hazards. This not only supports regulatory compliance but also bolsters operational efficiency, risk mitigation, and overall business resilience.

Workplace exposure - Direct-reading low-cost particulate matter sensors for measuring airborne NOAA - Guidelines for application
CEN/TS 18086:2024 addresses a critical need in modern occupational environments: low-cost, rapidly deployable sensor networks for monitoring airborne engineered nano-objects, agglomerates, and aggregates (NOAA). As industries increasingly employ nanomaterials and ultrafine particulates, continuous risk assessment via real-time monitoring is indispensable.
Scope and Application:
The standard guides the selection, use, calibration, and evaluation of low-cost optical particulate matter sensors in the workplace, with a particular focus on nano-objects and their agglomerates/aggregates.
It is informed by extensive laboratory and workplace testing and tailors recommendations for process control in NOAA-producing facilities.
While optimized for NOAA, the guidelines also support monitoring of other inhalable airborne particles encountered during routine plant operations or downstream handling.
Key Requirements and Features:
Sensor Types: Focuses on advanced photometer and photometer modules capable of providing size-integrated mass and/or number concentration data.
Calibration and Adjustment: Details robust approaches for laboratory and workplace calibration to account for varied particle size distributions, compositions, and environmental factors.
Limitations and Best Use: Emphasizes that current low-cost sensors are for indicative monitoring, not regulatory compliance, due to particle size detection limits (generally above 0.3 μm).
Quality Assurance: Includes guidance for sensor comparability, adjustment factors, and error source identification.
Implementation: Outlines strategies for setting up sensor networks, leveraging high spatio-temporal resolution to pinpoint exposure patterns, and integrating warning systems for exposure peaks.
Who Should Comply:
Nanomaterial production plants
Research labs handling nanoparticles
Manufacturing and assembly environments using process-generated ultrafine dusts
Occupational hygienists and safety professionals deploying air monitoring networks
Practical Implications: Adopting this standard allows organizations to establish cost-effective sensor networks, gain faster insights into changing workplace air quality, and trigger preventive actions before exposures escalate—all while optimizing process efficiency and demonstrating a best-practice approach to stakeholders and regulators.
Key highlights:
Enables dense, real-time sensor networks for dust monitoring
Detailed calibration and adjustment protocols for workplace conditions
Supports process control and exposure mitigation to engineered nanomaterials

EN 15051-2:2025 - Measurement of the Dustiness of Bulk Materials, Part 2: Rotating Drum Method
Workplace exposure - Measurement of the dustiness of bulk materials - Part 2: Rotating drum method
This standard delivers a reproducible method for quantifying the dustiness of powdered, pelletized, or granular bulk materials using a rotating drum apparatus. It’s designed for industries where bulk material handling is routine, such as mining, processing, manufacturing, and logistics.
Scope and Application:
Specifies the design and operation of the rotating drum test apparatus for generating dust under controlled, repeatable conditions.
Measures inhalable, thoracic, and respirable dust mass fractions, facilitating comparison and risk categorization of bulk materials.
Suitable for processes where materials are dropped or could be dropped repeatedly—the typical case for many industrial operations.
Key Requirements and Features:
Environmental Control: Precise specifications for relative humidity, temperature, and bulk material conditioning to ensure standardization.
Replicate Testing: Requires five repeat tests per material for reliable categorization, including detailed protocols for cleaning, weigh-in, and handling.
Analytical Methodology: Uses gravimetric analysis to determine the mass of particles collected on foams and filters across size fractions.
Categorization Scheme: Results are standardized with category thresholds for dustiness, allowing organizations to comparatively assess and select safer materials.
Quality Assurance: Includes flow rate and leak checks, use of reference powders (e.g., Spheriglass), and procedures for outlier detection.
Who Should Comply:
Bulk material suppliers and processors
Manufacturers selecting or substituting raw materials
Occupational hygienists tasked with risk assessments of airborne particulate exposure in handling and processing environments
Regulatory bodies monitoring compliance
Practical Implications: Implementing EN 15051-2:2025 helps companies proactively identify high-dust materials, optimize workplace controls, justify material substitutions, and validate risk-reduction strategies. Compliance builds confidence with employees and regulators while lowering the likelihood of costly incidents.
Key highlights:
Offers standardized, repeatable testing for material dustiness rating
Essential for safer material selection and process design
Integrates advanced quality control and environmental condition requirements

EN 15051-3:2025 - Measurement of the Dustiness of Bulk Materials, Part 3: Continuous Drop Method
Workplace exposure - Measurement of the dustiness of bulk materials - Part 3: Continuous drop method
EN 15051-3:2025 introduces the continuous drop method, simulating processes where bulk materials are dropped continuously—mirroring realistic workplace scenarios like conveyor belt loading, bag filling, or hopper discharge. This advanced approach complements the rotating drum method by better representing dust generation during continuous operations.
Scope and Application:
Defines the design, preparation, and operation of continuous drop test apparatus.
Focuses on measuring the inhalable and respirable dustiness mass fractions under standard laboratory conditions, with thoracic fraction as an optional extension.
Used where bulk material processing involves uninterrupted flow or transfer, giving stakeholders more relevant exposure data for such operations.
Key Requirements and Features:
Apparatus Design: Outlines apparatus configuration, environmental grounding, and flow control for precise measurement.
Sample and Environmental Conditioning: Stringent conditioning of materials regarding humidity and temperature to ensure accurate, reproducible outcomes.
Test Procedure: Step-by-step guidance on sampling, continuous dropping, collection, and gravimetric analysis of airborne fractions.
Standardized Reporting: Specifies data calculation, result presentation, and dustiness categorization (for both inhalable and respirable fractions).
LOD/LOQ Protocols: Requirements for reporting limit of detection and quantification to ensure data reliability.
Who Should Comply:
Industries with bulk material transfer (agriculture, pharmaceuticals, construction, chemicals)
Occupational hygienists assessing risk in continuous material handling operations
Product developers comparing the dust emission profiles of new and existing materials
Practical Implications: By applying EN 15051-3:2025, organizations better simulate real-world dust exposure scenarios. The insights gained support evidence-based adjustments to process engineering, material selection, and control strategies, leading to healthier—and more scalable—production environments.
