Finnish M1 label was updated with significant changes


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.

Main changes implemented:

  • Loading factors for chamber emission testing are adapted from CEN/TS 16516.
  • TVOC definition is harmonized with CEN/TS 16516.
  • Several details on how to make a test specimen of a product sample are revised.
  • Open storage of test samples before the 28 days no longer is allowed; storage must occur in a test chamber or in a separate storage chamber under controlled conditions.
  • Odour testing no longer requires a separate odour test chamber. Instead, an ISO 16000-28 acceptability odour test is required, e.g. with sampling test chamber air into a gas bag right after the last air sampling after 28 days; odour will be determined then with the air from these gas bags.
  • Fixtures (mounted furniture, e.g. in built-in kitchens) are a new product group available for M1 labelling

Tests for other specifications

It is stated that tests made for other emission classification systems than M1 will be accepted, if the tests are performed by an M1 approved lab, and following the M1 testing methodology. But at the same time, some changes of the test method increased the differences from other low VOC specifications, especially for some paints and for adhesives, but also for doors, windows, and “fixtures” (mounted furniture e.g. in built-in kitchen).

Eurofins Product Testing A/S is working on a solution for combining M1 tests with other tests, such that manufacturers can order one single combined test and receive test data that can serve all low VOC emissions specification across whole Europe, if not even globally. This is possible already today, but the new changes in the M1 test method require a revision of this approach if M1 shall be included in such a global VOC emissions test.
