ISO 22632:2019 pdf – Adhesives — Test methods for adhesives for floor and wall coverings — Shear test.
1 Scope This document specifies a test method to measure the adhesion of a 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.

5.3 Heating chamber, ventilated and adjustable to a temperature between 20 °C and 200 °C according to ISO 9142. 5.4 Tensile testing machine, conforming to ISO 7500-1, class 1. 5.5 Primer, if applicable. 5.6 Test covering, five test pieces for each conditioning sequence of dimensions 60 mm × 50 mm, the long side, running in the machine direction where this can be identified, and shall be taken at least 10 mm from the edge. 5.7 Substrate materials. Use either fibre cement or plywood as the substrate. 5.7.1 Fibre cement substrate, one uncoated fibre cement panel, fully compressed and autoclaved, for each test piece. Five fibre cement panels for each conditioning sequence with a length of approximately 60 mm and a thickness of approximately 8,0 mm. The width is (50 ± 0,5) mm. NOTE Length and thickness are not critical. Depending on the source of the fibre cement panels, the surfaces sometimes differ with respect to gloss, absorbency and strength. In this case, it is important to do some preliminary assessment (i.e. peel tests) of the panels to identify the preferred side for testing. The preferred side is referred to as the upper side of the substrate in this document.
5.7.2 Plywood substrate, one uncoated plywood panel for each test piece. Five plywood panels for each conditioning sequence with a length of approximately 60 mm and a thickness of approximately 5,0 mm. The width is (50 ± 0,5) mm. NOTE Length and thickness are not critical. 6 Preparation of the test specimens 6.1 Cleaning Ensure that all test coverings and substrate materials are clean and free from dust, loose particles or other contamination. 6.2 Sampling of adhesive Take a sample in accordance with ISO 15605 of the adhesive to be tested and examine and prepare it in accordance with EN 1067. 6.3 Conditioning of materials 6.3.1 Adhesive and floor and wall coverings Condition the materials at a standard atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity in accordance with ISO 554 for at least 24 h prior to use. 6.3.2 Fibre cement substrate Place the test panels (5.7.1) in a heating chamber (5.3) for 6 h at (80 ± 2) °C. Ensure that the test panels are spaced in such a way as to enable a free passage of air over them. At the end of this period, remove the test panels from the heating chamber and store for 48 h in a standard atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity prior to use. 6.3.3 Plywood substrates Condition the materials at a standard atmosphere of (23 ± 2) °C and (50 ± 5) % relative humidity in accordance with ISO 554 for at least 24 h prior to use. 6.4 Application of adhesive Place masking tape across one end of the upper side of each substrate leaving a 20 mm length to be coated with adhesive.
