标准范围
This document specifies a method for evaluating the adhesion of elastic adhesives and sealants [with 1) a minimum elongation at break of 100 % and a modulus of elasticity of maximum 10 MPa ] on various substrates. In this way, the effect of various coatings or the surface pre-treatments of the substrate materials on the adhesion can be compared. It can also be used to evaluate the influence of pre- treatment, substrate and adhesive on the long-term durability of adhesively bonded joints and seals. This test can also be used for process monitoring and quality assurance accompanying production.
