Full title and description

ISO 10396:2007 — Stationary source emissions — Sampling for the automated determination of gas emission concentrations for permanently‑installed monitoring systems. This International Standard specifies procedures and equipment to obtain representative samples from effluent gas streams for automated gas concentration measurement by permanently installed monitoring systems.

Abstract

ISO 10396:2007 defines sampling methods and necessary sampling equipment to permit, within specified limits, representative sampling of stationary-source effluent gases for automated determination of gas concentrations. The standard is limited in application to the determination of oxygen (O2), carbon dioxide (CO2), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen monoxide (NO) and nitrogen dioxide (NO2), and the combined NO + NO2 expressed as nitrogen oxides (NOx). It addresses both extractive (conditioned) and in‑situ approaches appropriate for permanently‑installed monitoring systems.

Scope

The standard covers sampling procedures and the required sampling‑system components for permanently installed automated monitoring systems used at stationary emission sources. It specifies how to obtain representative samples for the automated determination of the listed gases (O2, CO2, CO, SO2, NO, NO2 or NOx), including requirements for sampling points, probe design, sample extraction and conditioning (where applicable), handling of aerosols/particulates and moisture, and limits/conditions under which representative sampling is expected. ISO 10396 is intended for use in routine emissions monitoring and as a technical reference for the design and installation of sampling lines and sample conditioning for automated gas analysers.

Key topics and requirements

• Definition of representative sampling objectives for permanently‑installed automated monitoring systems.
• Guidance on selection and location of sampling points within ducts and stacks to achieve representative samples.
• Design and materials for sampling probes and extraction systems suitable for target gases and process conditions.
• Requirements for sample conditioning where extractive sampling is used (removal of aerosols/particulates, moisture control, filtration and temperature control).
• Differences and requirements for extractive (conditioned) versus in‑situ (unconditioned or minimally filtered) measurements.
• Flow handling, transport lines, and prevention of sample alteration en route to analysers.
• Calibration, routine checks, and maintenance considerations to preserve sample representativeness and measurement integrity.
• Documentation, record keeping and reporting elements necessary for traceability and compliance.
• Performance limits and practical constraints (operating temperature, particulate loading, corrosive species) that influence sampling strategy.

Typical use and users

ISO 10396:2007 is used by air emissions and environmental compliance teams, environmental consultants, process/plant engineers, instrumentation and monitoring equipment manufacturers, testing and calibration laboratories, and regulatory authorities. Typical applications include continuous emissions monitoring at power plants, industrial boilers, incinerators, chemical plants and other stationary sources where permanently installed monitoring systems measure gas concentrations for process control, reporting and regulatory compliance.

Related standards

Relevant and commonly associated standards include other documents from the ISO/TC 146/SC 1 portfolio that address stationary source emissions, particulate measurement and automated monitoring system performance (for example ISO 9096 on particulate matter measurement and ISO 10155 on automated particle monitoring). National or regional equivalents and adoptions (technical translations or identical standards) also exist. ISO 10396:2007 itself replaced the earlier ISO 10396:1993.
