Emission of volatile pollutants from Burgundy Limestone

THE LABELLING OF CONSTRUCTION AND DECORATION PRODUCTS IS OBLIGATORY SINCE 1ST JANUARY 2012

An analysis of the emission of organic pollutants from interior cladding in Burgundy limestone has been undertaken by the CTMNC to prove it is innocuous.

The total COV (Volatile Organic Compositions) of natural Burgundy limestone have not been measured above the AFSSET specifications over 28 days. No phtalates, benzene nor trichloroethylene have been detected above thelimits over 28 days. The same applies for the 11 other substances controlled (see list below)

Information regarding the emission level of volatile substances in interior air presenting a risk of intoxication by inhalation, on a scale going from A+ (very small emissions) to C (strong emissions)
