Finnish M1 label was updated with significant changes
Wednesday, January 8, 2014
M1 is the short version name of the Finnish voluntary emission classification of building materials. M1 is the name of the lowest emission class of that system. The emission classification of construction products for interior use is based on an emission chamber test after 28 days.
Also in future, M1 requires ammonia and odour testing on top of 28 days VOC and formaldehyde testing, distinguishing the M1 label from any other low VOC specifications around the Globe.
But a number of significant changes of the M1 label were implemented with validity from 1st January 2014. You can read more about the changes, and what they mean for manufacturers of concerned products, in our VOC blog.
