Finnish emissions label for construction products and furniture

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.
