Full title and description
ISO 20581:2016 — Workplace air — General requirements for the performance of procedures for the measurement of chemical agents. This International Standard defines general performance requirements that measuring procedures (sampling plus analysis, or direct‑reading methods) must meet when used to determine concentrations of chemical agents in workplace atmospheres.
Abstract
ISO 20581:2016 specifies general performance requirements for procedures to determine the concentration of chemical agents in workplace atmospheres (gases, vapours and airborne particles). It covers all measurement steps, whether separate sampling and analytical methods or direct‑reading devices, and defines test conditions and performance criteria to reflect a range of environmental conditions encountered in practice.

Scope
ISO 20581:2016 applies to procedures for measuring concentrations of chemical agents in workplace air and sets general performance requirements that such procedures must meet. The scope includes measurements for screening, for assessing spatial or temporal variability, for comparison with occupational exposure limits, and for periodic measurements; it addresses selectivity, averaging time, measuring range, expanded uncertainty and method robustness under environmental and handling conditions.
Key topics and requirements
- Classification of measurement objectives (screening, variability, comparison with limit values, periodic monitoring).
- Performance criteria: selectivity, unambiguity, measuring range, averaging time, expanded uncertainty.
- Requirements for composite procedures (sampling + analysis) and direct‑reading devices.
- Considerations for transport, handling and storage of samples and for environmental test conditions to reflect workplace variability.
- Guidance where compliant methods are not available for specific chemical agents.
Typical use and users
Intended users include occupational hygienists, industrial hygiene laboratories, method developers and validators, employers responsible for exposure assessment, regulators and standards developers. The standard is used to evaluate or design measuring procedures, to interpret measurement results against performance criteria, and to document method performance for compliance and quality assurance purposes.
Related standards
ISO 20581 is part of the wider body of workplace‑air standards. Closely related documents include ISO 18158 (workplace air — terminology), standards on sampling and sampler testing such as ISO 22065 (pumped samplers) and ISO 13137, and particle/sampler standards adopted as EN/ISO 23861. These complementary standards cover terminology, sampler performance, particle fraction definitions and specific method validations that together support consistent workplace air monitoring programs.
Keywords
Workplace air, measurement procedures, sampling, analytical method, direct‑reading devices, chemical agents, performance requirements, uncertainty, occupational exposure, method validation.
FAQ

Q: Who typically uses it?
A: Occupational hygienists, analytical laboratories, method developers, employers conducting exposure assessments, regulators and standards developers use this standard to develop, assess and document measurement procedures for workplace air monitoring.
Q: Is it current or superseded?
A: ISO 20581:2016 is the first edition (published November 2016) and was confirmed following ISO’s systematic review process (review closed and confirmation recorded in 2022).
