ISO 34256:2024

This document specifies a method for determining the ability of a test piece bonded with a thermoplastic adhesive, to support a given load for a specified time without fracture or excessive distortion, and specifies performance requirements for mean survival time. It should be used in conjunction with ISO 19209 and ISO 19210, which describe durability classes and corresponding test methods for non-structural wood adhesives based on their ability to withstand various water treatments and relatively rapidly applied loads. The test described in this standard may be used to assess joints made with thin glue line, as defined in ISO 19210. NOTE            The test described in this document is not a mandatory requirement for the classification of adhesives into the classes D1, D2, D3 and D4 given in ISO 19209. It is an additional test that can be specified by a purchaser if required.
