This standard BS ISO 21194:2019 Elastic adhesives. Testing of adhesively bonded joints. Bead peel test is classified in these ICS categories:
83.180 Adhesives
This document specifies a method for evaluating the adhesion of elastic adhesives and sealants [with a minimum elongation at break of 100 % and a modulus of elasticity of maximum 10 MPa1
1
The elongation and modulus of elasticity are measured according to ISO 527-2.
] 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.
