What is the M1 Certificate?

What is M1 Certifitate?

The criteria for M1-certified building material were developed and published for the first time over 20 years ago in 1996. M1-classification sets limit values for the emission of VOC, formaldehyde, ammonia also the acceptability of the odor associated with the material is assessed.

M1-label on the product tells that the product complies with the M1-criteria for emission and odor. The aim of the classification is to enhance the development and use of low-emission building materials and furniture.

Building Information maintains and publishes a freely accessible database. All products with valid M1-certificate can be found in the database using the search function.

Companies that have been granted the right of use of the M1 label may use it for marketing purposes. The classification label shall not be used in marketing in such a way that it refers to the company as a whole or to products that have not been granted M1 classification.

Voluntary labeling system

The emission classification of building materials is a voluntary labeling system open to all manufacturers, importers, and exporters of building products. Many developers, architects, and designing engineers favor M1-certified products when selecting materials for their projects.

The Finnish Association of Building Owners and Construction Clients RAKLI, the Finnish Association of Architects SAFA, and the Finnish Association of Consulting Firms SKOL recommend their members the M1-classification system in order to promote high-quality construction.

The M1 certification body is the Building Information Foundation RTS sr
