ISO 19993:2020 PDF Download

ISO 19993:2020 standard establishes methods for evaluating the quality of glued laminated timber face and edge joints in a manufacturing environment. The standard focuses on assessing the effectiveness of these bonds by conducting cleavage tests, both in dry and wet conditions.

It should be noted that ISO 19993:2020 is not intended for initial type testing, where cyclic delamination or block shear testing is preferred. Instead, the standard is designed to determine whether the bond strength of the glued laminated timber exceeds the perpendicular to the grain tension strength of the underlying substrate. This principle ensures that the bond is not the weak element that compromises the integrity of a glulam assembly.

By using the methods specified in this standard, manufacturers can evaluate the strength and reliability of the glulam face and edge joints, providing a basis for ensuring the quality and safety of timber structures. ISO 19993:2020 plays an important role in promoting the use of glued laminated timber in construction, enhancing the confidence of designers, builders, and users in the structural performance of these timber components.
