Select the substrate material(s) from mortar and/or anodized aluminium and/or glass. Other substrate materials may be used as agreed bythe parties concerned. For each test specimen, two substrate pieces of the same material are required with a cross-section of dimensions of thesealantbeadandthe area of adhesionshallbethesame asthoseshown inFigures1 and 2. and2),withanti-adherentsurface. 5.3. Anti-adherent substrate, for the preparation of the test specimens, e.g. polyethylene (PE) film, preferably according to the advice of the sealant manufacturer. 1 Tensile test machine, capable of extending the test specimens at a rate of (5,5 ± 0,7) mm/min 5.4 5.5 5.6 5.7 Container, for immersing test specimens in distilled water (conditioning method B) 5.8 Container, for immersing test specimens in water at (23 ± 2) °C. 5.9 Measuring device, scaled to 0,5 mm 6 Preparation of test specimens The sealant and substrate shall be brought to (23 ± 2) °C. For each substrate material, three test specimens The instructions of the sealant manufacturer shall be followed concerning, for instance, whether a primer is to shall be filled with the sealant. The following precautions shall be taken; a) the formation of air bubbles shall be avoided; b) the sealant shall be pressed on the inner surfaces of the supports; c)the sealant surface shall be trimmed so that it is flush with the faces of the supports and spacers The test specimens shall be set on the edge of one of the supports. The anti-adherent substrate shall be of the sealant. The spacers shall be maintained in place during conditioning Co
