For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 6927, Building construction — Jointing products — Sealants — Vocabulary ISO 1 3640, Building construction — Jointing products — Specifications for test substrates 3 Terms and definitions For the purposes of this International Standard, the terms and definitions given in ISO 6927 apply. 4 Principle Test specimens are prepared in which the sealant to be tested adheres to two parallel contact surfaces. After submission to cycles of compression and extension under defined conditions, the test specimens are examined for evidence of loss of adhesion and cohesion. 5 Apparatus 5.1 Substrate materials, used for the preparation of test specimens, shall be as defined in ISO 1 3640. Select the substrate material(s) from mortar and/or anodized aluminium and/or glass. Other substrate materials may be used as agreed by the parties concerned. For each test specimen, two substrate pieces of the same material are required with a cross-section of dimensions as shown in Figures 1 and 2. Test substrates of other dimensions may be used, but then the dimensions of the sealant bead and the area of adhesion shall be the same as those shown in Figures 1 and 2. 5.2 Spacers, for the preparation of the test specimens, of cross-section with anti-adherent surface (see Figures 1 and 2). 5.3 Anti-adherent substrate, for the preparation of test specimens, e.g. polyethylene (PE) film, preferably according to the advice of the sealant manufacturer. 5.4 Ventilated convection-type oven, capable of being maintained at .5.5 Refrigerated enclosure, capable of holding the test specimens during extension at a temperature of . 5.6 Container for water immersion of the specimen for conditioning...
