Quality documentation and certification

Treteknisk plays an important role as a testing laboratory, as well as a certification body. The demand for these kinds of services are increasing, due to authorities’ requirements for documentation, and the market demand for documented product properties. The institute has invested in competence, laboratory equipment, a comprehensive quality system and the formal status to be an internationally recognized testing and inspection body for the wood industry.

Since 1994, the laboratory has been accredited for mechanical testing according to EN ISO/IEC 17025, and from 2015 accredited according to EN ISO/IEC 17065. The institute is appointed by the Ministry of Trade and Industry as notified body for attestation of conformity with the Construction Products Regulation (CPR). This applies to structural timber products and wood based panels. This means that the institute can perform testing and certification as basis for CE marking of building products.


Treteknisk has for several years worked with product certification, for JAS (Japanese Agricultural Standardisation), CE marking and PEFC certification.


PEFC documents that a product originates from sertified wood, verified by a third body. Both EUTR (EU’s timber regulation) and BREEAMNOR requires such certifications.

Japan – JAS-certification

The institute has gained a leading position in Europe concerning JAS-sertification of glulam. Several glulam companies, sawmills and CLT companies have their JAS-certification through Treteknisk.
