Are there standards for grading reclaimed timber?

Yes. Reclaimed timber can be graded to EN 14081 using the same visual or machine methods applied to new timber.

Yes. Reclaimed timber can be graded to EN 14081 using the same visual or machine methods applied to new timber. In the UK, BS 8539:2012 provides specific guidance on the assessment and reuse of reclaimed timber. The grading process must account for: existing damage (bolt holes, notches, splits), degradation (decay, insect damage), and contamination (paint, preservatives, metal inclusions). Reclaimed timber that passes grading carries the same structural design values as new timber of the equivalent grade.
