Volatile organic compounds-VOC

Volatile organic compounds (VOC) are components which, at room temperature, may be released from materials or products in the form of gases. Classification is conducted by means of the boiling points in compliance with the WHO definition. To differentiate them against other components, compounds in a boiling range from 50 °C to 260 °C are therefore called VOC.

The emission range of volatile organic compounds is characteristic and a fingerprint of the product. The emission behaviour, i.e., the range of volatile organic compounds, is strongly influenced by the material’s age and background, so that emission tests should be conducted primarily on fresh products.

Of the multitude of volatile organic compounds, only a very few are able to have an impact on the odour development of materials.

Definition of VOCīs according to the AgBB-scheme - TVOC

Within the AgBB scheme, volatile organic compounds include compounds within the retention range of C6 to C16, which are considered both as individual substances and in calculating a sum parameter following the TVOC concept (TVOC = Total Volatile Organic Compounds), and semivolatile organic compounds (SVOC) within the retention range from C16 up to C22.
