Emission testing of building materials

Our emission testing provides reliable information on building materials’ emissions. Our high-quality material emission services consist of three products that are suitable for different applications: bulk or total emission, FLEC (Field and Laboratory Emission Cell), and surface emission testing with a chamber technique.

The testing can be used for purposes such as applying the Finnish M1 classification to the product or assessing the impact of material emissions on the chemical quality of indoor air.

There are three methods for studying building material emissions

There are three different methods for investigating the emissions of building materials. 

Both bulk emission and FLEC are well-established as methods for solving indoor air problems, and you can find more information about them on our Indoor air laboratory analysis page. 

The least known of the three is a surface emission study with a chamber. The chamber technique, conducted under standardised conditions and based on the ISO 16000-9 and SFS-EN 16516 standards, provides reliable information on building materials’ emissions. 

The chamber technique also enables assessment of the impact of material emissions on the chemical quality of indoor air, as the result includes a model room concentration in addition to the surface emission rate.

The testing can be used for applying for the Finnish M1 classification.

All three techniques can be used to analyse samples such as volatile organic compounds (VOC), formaldehyde and other aldehydes, and ammonia. 

The material emission service can help you in product development, quality control, and solving indoor air problems

Our material emission services can be customised, for example: 

  • to support product development process 
  • as part of material manufacturers’ quality control 
  • to support indoor air analysis in identifying problematic materials 

Our other related laboratory services: 

  • testing services for emissions generated during the manufacturing process and thermal decomposition products 
  • dustiness testing of materials in accordance with SFS-EN 15051-2 

We provide reliable and high-quality services

The Laboratory Services of the Finnish Institute of Occupational Health is a testing laboratory T013 accredited by FINAS accreditation services, accreditation requirement SFS-EN ISO/IEC 17025:2017. Operations included in the accredited scope of competence are available on the website www.finas.fi.

Our laboratories are also approved by the Finnish Food Safety Authority to conduct analyses related to housing health and authorised by the Building Information Foundation to carry out laboratory tests required by the M1 classification.
