What is ISO 19993 about?   ISO 19993 discusses face and edge joint cleavage tests for glued laminated timber in timber structures. ISO 19993 is an international standard that provides effective evaluation for glued laminated timber joints.   ISO 19993 specifies methods to evaluate the effectiveness of glued laminated timber face and edge bonds within a manufacturing plant by cleaving glue lines in both dry and wet conditions.   ISO 19993 is used as a factory quality assurance test to be used for structural glulam and applied to the face and edge joints of each production batch.   Methods specified under ISO 19993 are based on the principle that if the minimum wood failure percentages are met then bond strength exceeds the perpendicular to the grain tension strength stating that the bond is not the weak element that limits the integrity of a glulam assembly.
