This document specifies a method for testing the strength of wood adhesives at 80 °C.
NOTE   The procedure described is based on a test developed in Germany known originally as the WATT '91 test. It uses the test piece described in EN 205.

This European Standard classifies thermosetting resin based wood adhesives for non-structural applications into durability classes C1 to C4 based on the dry and wet strengths of bond-lines measured under specified conditions after various conditioning treatments.
For special applications, further tests, which do not fall within the scope of this European Standard can be applicable.
The adhesives specified in this European Standard are suitable for the bonding of furniture and interior structures, panelling, doors, windows, stairs etc. made of wood or derived timber products.

This European Standard specifies tests for adhesives for wood and derived timber products for the assessment of their resistance to hot and cold water. It can be used for the assessment of the strength of bonds with a thin bond-line. It does not apply to adhesives for structural use or to the manufacture of particleboards, fibreboards and plywood. It does not replace tests on finished products.

This European Standard defines the test method for the determination of the maximum open time for thermoplastic wood adhesives for non-structural applications by tensile shear strength. It is carried out on standardized test pieces glued with increasing open times.

This European Standard 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 EN 204 and EN 205, 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 EN 205.
NOTE   The test described in this standard is not a mandatory requirement for the classification of adhesives into the classes D1, D2, D3 and D4 given in EN 204. It is an additional test that can be specified by a purchaser if required.

This document establishes a classification of wood adhesives for non-structural applications for exterior use without protection by an adequate surface coating.
This document specifies performance requirements and durability classes of such adhesives for use in an environment corresponding to the defined conditions.
The performance requirements of this document apply to the adhesive only, not to wooden products.
This document is primarily intended to assess the performance of adhesives. The requirements apply to the type testing of the adhesives. Production control activities are outside the scope of this document.
NOTE   For the assessment of end product bonding quality, see Annex A.

This document specifies a method for adhesives for wood and derived solid wood products for determining the shear strength and wood failure percentage of wood-to-wood adhesive bonds loaded in compression. These parameters allow to define different working properties of adhesives (e.g. final bond strength, pressing time, closed assembly time).
Annex A gives information required prior to testing.

This European Standard specifies a test method to determine the heat resistance of wood adhesives under static load and increasing temperature conditions. The test assesses the adhesive's ability to resist sustained or continuous loading at temperatures well above normal room temperature, or in conditions where service temperatures are variable or cyclic.
NOTE   The procedure described is based on a test developed in Switzerland, known as the HRT'92 test. It uses test pieces described in EN 302-1 and EN 205, a static loading device and a means for increasing test pieces temperature at a specific rate.
