Full title and description

ISO 10313:1993 — Ambient air — Determination of the mass concentration of ozone — Chemiluminescence method. Specifies a continuous-sampling chemiluminescence procedure (air drawn through a particle filter and reacted with an excess of ethylene in a reaction chamber) for measuring ozone in ambient air; intended for routine and reference measurements within its stated range.

Abstract

This International Standard defines the principle, sampling and sample‑conditioning requirements, apparatus (including photomultiplier detection), calibration/zeroing practices and expression of results for ozone measurement by chemiluminescence. The method applies to ambient ozone concentrations from about 2 μg/m³ up to 10 mg/m³ at the reference conditions given in the standard. The document was published in 1993 and has a 2024 amendment addressing the consensus value for the ozone absorption cross‑section at the mercury line.

Scope

Specifies a chemiluminescence method for the determination of the mass concentration of ozone in ambient air. The standard covers sampling (including particle filtration), instrument requirements, calibration and performance characteristics and the procedures necessary to obtain accurate mass‑concentration results within the method’s working range. The method is applicable for routine monitoring and for purposes requiring traceable analytical results.

Key topics and requirements

• Measurement principle: chemiluminescence from reaction of ozone with ethylene, detected by a photomultiplier; signal proportional to ozone concentration.
• Sampling: continuous draw at constant flow through a particle filter to protect the analyzer and reduce interferences.
• Calibration and zeroing: procedures and reference approaches required to report mass concentration at stated reference conditions.
• Working range and sensitivity: specified lower and upper concentration bounds (approximately 2 μg/m³ to 10 mg/m³) and performance expectations.
• Performance considerations: attention to interferences, sample‑line losses/reactions (e.g., with NO), and routine maintenance (filter changes, lamp/exciter checks, detector stability).
• Reporting: expression of results, units (mass concentration), and required metadata (sampling conditions, calibration status, any deviations from the method).

Typical use and users

Used by environmental and air‑quality laboratories, governmental monitoring networks, instrument manufacturers (for instrument design and verification), research institutions studying atmospheric chemistry and regulatory bodies that set or verify ambient ozone concentrations. The method is suitable for routine monitoring sites and for applications where chemiluminescence is chosen for its specificity and dynamic range.

Related standards

Standards addressing other ozone measurement methods and related quality/performance concepts include ISO 13964:1998 (air quality — ozone by ultraviolet photometric method) and ISO 6879 (performance characteristics and concepts for air quality measuring methods). These documents are commonly referenced together when establishing measurement programs and traceability.
