Specifies requirements for bonded finger joints and minimum requirements for the manufacture of cut, interlocking, bonded finger joints in structural timber members. Requirements are given for timber, adhesive, moisture content, cutting, bonding and preservative treatments and flame retardant treatments. This Standard is only applicable to finger joints between timber members of the same species type. Based on and technically equivalent to BS EN 385:1995.

This Standard specifies requirements for bonded finger joints and minimum requirements for the manufacture of cut, interlocking, bonded finger joints in structural timber members. Requirements are given for timber, adhesive, moisture content, cutting, bonding and preservative treatments and flame retardant treatments.This Standard is only applicable to finger joints between timber members of the same species type.Although most finger joints are produced in coniferous species this Standard also applies to broad leaved species where information is available to enable them to be satisfactorily bonded.It does not cover impressed (die-formed) joints. In the case of glued laminated timber it applies only to individual laminations.
