Emission Classification of Building Materials
In 1995, the first version of the Finnish emissions classification was developed as part of the Classification of Indoor Climate, Construction, and Finishing Materials by the Finnish Society of Indoor Air Quality and Climate (FiSIAQ) and was awarded in 1996 for the first time.
Today, the Finnish quality label for construction products ranks among the leading quality labels of Scandinavia. It is granted in three categories – of which M1 is the best one and stands for low-emission – by the Building Information Foundation RTS sr.
Testing and criteria
To be granted the quality label, an emission test (incl ammonia, formaldehyde, and carcinogenics) and an odour test have to be perfomed on the construction product. The time period of testing is 28 days.
The criteria and processes are stipulated by the Committee Indoor Air Classification ( PT17) being appointed by the general manager of the Building Information Foundation RTS.
|Criteria / Classification||M1 (mg/m2h)||M2 (mg/m2h)||M3 (mg/m2h)|
|TVOC (Minimum of 70 % of compounds must be marked)||< 0,2||< 0,4||> 0,4|
|Formaldehyde (HCOH)||< 0,05||< 0,125||> 0,125|
|Ammonia (NH3)||< 0,03||< 0,06||> 0,06|
|Carcinogenic compunds belonging to category 1 der IARC monographs (IARC 1987)*
|Odour (dissatifaction must be below 15 %)**||no odour||no odour||odour|
*IARC 1987, does not apply to: formaldehyde (IARC 2004)
** Result of sensory evaluation must be > + 0,0.
