This document specifies a series of methods for the determination of peel adhesion properties of self adhesives tapes. This document contains: — Method 1: Self adhesive tapes ? Measurement of peel adhesion from stainless steel at an angle of 180°; — Method 2: Self adhesive tapes ? Measurement of peel adhesion from its own backing at an angle of 180°; — Method 3: Self adhesive tapes ? Measurement of peel adhesion of double sided and transfer tapes at an angle 180°; — Method 4: Self adhesive tapes ? Measurement of adhesion of the liner to an adhesive tape at an angle of 180°. Annexes A and B specify further variations in the testing protocol according to specific conditions.

This document specifies a method of determining the ability of adhesive bonds to resist long-term sustained load applied vertical to the glue lines. It is applicable to adhesives used in load-bearing timber structures. It is suitable for the following applications: a) for assessing the compliance of adhesives according to EN 15425 and EN 16254; b) for assessing the suitability and quality of adhesives for load-bearing timber structures; c) for assessing the effect on the bond strength resulting from long-term sustained load at cyclic climate conditions. This method is intended primarily to obtain performance data for the classification of adhesives for load bearing timber structures according to their suitability for use in defined climatic environments. This method is not intended to provide data for structural design, and does not necessarily represent the performance of the bonded member in service.

This document specifies a method for determining the creep deformation of bonded specimens loaded in bending shear. It is applicable to adhesives used in load bearing timber structures. It is suitable for the following applications: a) for assessing the compliance of adhesives to EN 15425 and EN 16254; b) for assessing the suitability and quality of adhesives for load bearing timber structures. This test is intended primarily to obtain performance data for the classification of adhesives for load bearing timber structures according to their suitability for use in defined climatic environments. This method is not intended to provide data for structural design, and does not necessarily represent the performance of the bonded member in service.

This document specifies a laboratory method of determining the open assembly time in standard climate (20 ± 2) °C and (65 ± 5) % relative humidity (hereafter climate [20/65]). This document is intended to determine the open assembly time using a defined procedure for obtaining a reliable base for comparison of open assembly time between adhesives under referenced conditions. The method gives a result that cannot be applied to the safe manufacture of timber structures without taking into account the influence of factors such as timber density, moisture content, factory temperature and relative air humidity.

This document specifies a laboratory method of determining the minimum pressing time for line thicknesses close contact, 0,2 mm, 0,3 mm and 0,5 mm, at three temperatures and three wood moisture contents. This document is intended to determine the minimum pressing time using a defined procedure for obtaining a reliable base for comparison of minimum pressing time between adhesives under referenced conditions. The method gives a result that cannot be applied to the safe manufacture of timber structures without taking into account the influence in variation of factors such as timber density, moisture content, factory temperature and relative air humidity.
