This standard specifies requirements for large finger joints and minimum requirements for the production of these in structural members of glued laminated timber also with corner pieces of laminated veneer lumber or plywood with a finger length of at least 45 mm. The glued laminated timber and the laminated veneer lumber shall be made from conifers and poplar. Such finger joints may be employed for joints in straight beams or for frame corners, see Figure 1.
