Wood products have a future because they are ecological, they have good conditions to convert as a component and the final product is magnificent. Besides wood is suitable for recycling.

Especially in Scandinavia and Great Britain both machine strength graded softwood as visual graded softwood is used. In what way pale? Machine strength graded wood was more reliable! The development of machine strength graded wood has eventually lead to a shifting in the way of testing.

Within NEN-EN 14081-1 you can choose to grade wood mechanical of visual. Of course you can also choose for both options, but then you have to show that you are in the possession of both disciplines and know how to control them. Engineering firm Evan Buytendijk BV advices with pleasure about this subject.

Strength grading machines 
Because of the shifting in the tests traditional bending machines are mainly replaced through machines which determine the strength on the basis of among other things vibration or a combination of skills such as X-ray. The most occurred machines at this moment are: Computermatic, Dynagrade, Goldeneye, Viscan, Finscan (BoardMaster) and until recently the Timber Grader MTG (Brookhuis).
