Quality Assessment


The “Quality Assessment” department focuses on projects concerning formaldehyde testing methods as well as bonding, bonded joints and adhesives for products using and made from renewable raw materials. Within an interdisciplinary team, we develop solutions for and with customers from, amongst others, the forestry and timber, construction, furniture and chemical industries

In certified further training courses at our WKI | AKADEMIE®, we make available the expertise which we have gained from the contact to manufacturers and through our research work. Our department is furthermore internationally recognized as a testing, monitoring and certification body and is therefore a competent contact partner for all questions relating to TMC.

Research Focuses


Formaldehyde testing methods

We do not only test products regarding formaldehyde – we also apply our years of experience to further develop the testing procedures.


Gluing, bonding and adhesives

We develop and optimize adhesive systems for the production of wood-based materials and for wooden construction.

Testing, Monitoring and Certification (TMC)


TMC | Testing

We perform accredited tests concerning the release of formaldehyde as well as regarding the surface and mechanical properties of wood, wood-based materials and products produced therefrom. We also test adhesives and bondings for wooden construction.


TMC | Monitoring

We verify the compliance of your in-house production control with the standards requirements for the European, American and Japanese markets.


TMC | Certification

We certify building products in accordance with the Construction Products Regulation. Furthermore, we also certify wood-based materials regarding formaldehyde in Europe, America and Japan.

Further training and Technology transfer



With the WKI | AKADEMIE®, we offer you in-service training in the field of wood-based materials production and wood construction.
