CEN PREN 13649: Stationary source emissions - Determination of the mass concentration of individual gaseous organic compounds - Active carbon and solvent desorption method

This European Standard specifies procedures for the sampling, preparation and analysis of individual volatile organic compounds (VOCs) in waste gas, such as those arising from solvent using processes. It is a reference method.

The results obtained using this standard are expressed as the mass concentration (mg/m³) of the individual gaseous organic compounds. This Standard is suitable for measuring individual VOCs ranging in concentration from about 0,5 mg/m³ (solid adsorbent/solvent extraction methods) or from about 0,005 mg/m³ (thermal desorption methods). The upper range is defined by the method selected.

An alternative Method may be used provided that the user can demonstrate equivalence to this method according to the Technical Specification CEN/TS 14793, to the satisfaction of his national accreditation body or law.

This standard may be used to meet the monitoring requirements of applicable EC Directives.

This standard may be used for other organic compounds where validated.

This standard is not suitable for measuring total organic carbon (TOC). For the measurement of the mass concentration of total organic carbon then EN 12619 is applicable.
