M1 Finnish label
M1 is the short version name of the Finnish voluntary emission classification of building materials. It is the lowest emission class of that system.
VOC emission classification of construction products is based on VOC emission chamber test, and on an odour test, both after 28 days.
M1 is administered by RTS. For more details, please visit RTS website.
Eurofins Product Testing A/S is one of the approved laboratories for M1 labelling.
Eurofins offers documentation of compliance with above specifications on emissions of VOC, aldehydes, ammonia and odour by independent testing.
Costs can be saved if a M1 test is combined with other VOC emissions testing. But please note that
- RTS requires that the whole M1 test is performed with the same sample and at the same time for avoiding any error by ageing of sample; you cannot first perform VOC and formaldehyde tests for other purposes and then later decide to add the tests that are missing for M1 (ammonia and odour) without repeating VOC and formaldehyde testing.
- RTS requires to approve in advance the selection of representative or worst-case sample for covering a whole group of products; this decision by Finnish RTS can be different from the decision by others on the same subject (e.g. German DIBt or Blue Angel).
