Volatile organic compounds (VOCs) are a set of substances belonging to different chemical classes that evaporate more or less quickly at room temperature: benzene, styrene, toluene, trichloroethylene, and other highly volatile substances such as formaldehyde and acetaldehyde.
Construction products, decoration, and furnishing products to be traded in France are labeled with an emissions classification ”VOC Emissions dans l'air intérieur” based on VOC emissions tests. This label provides information on emissions of volatile substances in a toxic threat during inhalation of indoor air on a scale from A+ (very low emission) to C (high emission).
