The standard’s requested system of assessment and verification of constancy of performance is System 1.
 
The product characterisation tests to be mentioned on the label include:
  • mechanical performance (bending strength, tensile strength etc.)
  •  bonding and lamination quality
  • durability performance
  • assessment of the release of dangerous substances (formaldehyde emission)
  • testing of finger joints
  • fire tests
 
CE marking of finger-jointed solid timber (e.g. KVH)
The normative reference is EN 15497 "Structural finger jointed solid timber - Performance requirements and minimum production requirements".
