Foreword
This document (prEN 302-5:2011) has been prepared by Technical Committee CEN/TC 193 “Adhesives for
wood and derived timber products”, the secretariat of which is held by AENOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede ENV 302-5:2001.
This document is one of a series dealing with adhesives for use with timber structures, and is published in
support to EN 1995 Eurocode 5: Design of timber structures. The series consists of a classification and
performance requirements for phenolic and aminoplastic polycondensation adhesives for use in different
climatic conditions (EN 301), five test methods (EN 302 Parts 1 to 4 and EN 15416-2) used to assess the
performance of adhesives after specified heat and humidity treatments, and three test methods (EN 302 Parts
5 to 7) to characterize the working properties of the adhesive.
EN 301, EN 302 Parts 1 to 7 and EN 15416-2 have the following titles.
EN 301, Adhesives, phenolic and aminoplastic, for load-bearing timber structures — Classification and
performance requirements
EN 302, Adhesives for load-bearing timber structures — Test methods
Part 1: Determination of longitudinal tensile shear strength
Part 2: Determination of resistance to delamination
Part 3: Determination of the effect of acid damage to wood fibres by temperature and humidity cycling on
the transverse tensile strength
Part 4: Determination of the effects of wood shrinkage on the shear strength
Part 5: Determination of the maximum assembly time under referenced conditions
Part 6: Determination of the minimum pressing time under referenced conditions
Part 7: Determination of the working life under referenced conditions
EN 15416-2, Adhesives for load bearing timber structures other than phenolic and aminoplastic — Test
methods — Part 2: Static load test of multiple bondline specimens in compression shear.
