ISO 22632:2019 Adhesives – Test methods for adhesives for floor and wall coverings – Shear test

ISO 22632:2019 Adhesives – Test methods for adhesives for floor and wall coverings – Shear test. This document specifies a test method to measure the adhesion ola resilient or textile floor covering or wall covering bonded to a given substrate under shear forces. The term “wall covering” does not include any type of wallpaper. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
