ISO 1519:1973 Bend test with cylindrical mandrel: Historical method for determining coating flexibility in material testing

/ / Published in ISO Test Methods, Science and Research

ISO 1519:1973 is an important test for evaluating the flexibility of coatings on metallic substrates. In this procedure, a coated metal sample is bent around a cylindrical mandrel and then examined for cracking or signs of delamination. The mandrel bend test enables a reliable assessment of the elasticity and adhesion of paints and varnishes under bending stress, which is essential for quality assurance…
