Material and Product Testing
The Entwicklungs- und Prüflabor Holztechnologie GmbH (EPH) provides a comprehensive programme of testing of all types of wood-based materials. The testing is based on national and international standards and guidelines. The tests are performed within the scope of third-party surveillance or of services. The EPH develops test programmes especially tailor-made to clients’ requirements for accompanying product developments.
