Emission testing of 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 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.

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
