This standard specifies tolerances on sizes of glued laminated timber for structural use and the reference moisture content at which sizes are established. It also gives a method for the calculation of corrected sizes for glued laminated timber with a moisture content differing from that of the reference moisture content.
It is applicable to glued laminated timber with rectangular cross sections having sizes in the range of:
width: 50 mm to 300 mm
depth: 100 mm to 2500 mm
