3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 6927 apply.
4 Principle
Test specimens are prepared such that the sealant to be tested adheres to two parallel contact surfaces. The cured and conditioned test specimens are compressed to a defined width and this compression is maintained under accelerated weathering conditions. The test specimens are then extended to a defined width and this extension is maintained under accelerated weathering conditions. The samples are evaluated to record any loss of adhesion or cohesion is recorded along with recording if light can be visible through the specimen.
5 Apparatus
5.1 Substrate materials. (or the preparation of test specimens as defined in ISO 13640. The substrate materials shaN be selected from mortar type 1 or type 2. 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 Figure L 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 Figure 1..
5.2 Spacers, cross section (12 mm x 12 mm) with anti-adherent surbce. For the preparation of test specimens see Figure 1.ISO 19862 pdf download.
