Overview

EN 481:1993 (adopted in national versions such as SIST EN 481:1998) is a CEN standard that defines sampling conventions for particle size fractions used in workplace atmospheres. The standard establishes how to classify airborne particles for exposure assessment so that measurements relate to potential health effects from inhalation. The conventions are based on experimental data for healthy adults and cover the inhalable, thoracic and respirable fractions; extrathoracic and tracheobronchial fractions can be calculated from these defined conventions.

Key Topics

  • Particle size fraction definitions: Clear conventions for what constitutes inhalable, thoracic and respirable fractions in occupational air monitoring.
  • Sampling conventions: Guidance on how to interpret measurements with respect to human respiratory deposition and health relevance.
  • Human-based data: Conventions are derived from experimental data for healthy adults to reflect realistic inhalation and deposition behavior.
  • Derived fractions: Notes that extrathoracic and tracheobronchial fractions may be calculated from the primary conventions rather than redefined.
  • Terminology and scope: Defines terms used in particle size measurement and limits the standard’s application to workplace atmospheres and occupational hygiene.

Applications

EN 481:1993 is practical for professionals involved in occupational air quality and aerosol measurement:

  • Occupational hygienists and industrial hygienists use the standard to select appropriate sampling strategies and interpret exposure data against size-relevant health risks.
  • Testing and analytical laboratories rely on the conventions to report particle concentrations in a way that is comparable across studies and compliant with regulatory frameworks.
  • Manufacturers of sampling equipment use the definitions to design and validate samplers aimed at inhalable, thoracic or respirable fractions.
  • Regulators and safety managers apply the standard when developing monitoring programs, setting workplace controls, and assessing compliance with exposure limits tied to particle size fractions.

Practical uses include designing monitoring programs, choosing samplers and inlets, interpreting aerosol measurement results, and informing risk assessments and control measures based on particle size–dependent health effects.

Related Standards

  • Standards addressing specific sampling methods, sampler performance and occupational exposure limits are typically used alongside EN 481:1993.
  • For comprehensive compliance and measurement programs, consult national adoption documents (e.g., SIST EN 481:1998) and relevant guidance from occupational health authorities.
