BRITISH STANDARD BS EN ISO 10591:2005 Incorporating amendment no. 1 Building construction Sealants Determination of adhesion/cohesion properties of sealants after immersion in water The European Standard EN ISO 10591:2005 has the status of a British Standard ICS 91.100.50 ? Licensed Copy: London South Bank University, London South Bank University, Sat Sep 01 03:23:56 GMT+00:00 2007, Uncontrolled Copy, (c) BSI BS EN ISO 10591:2005 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 18 November 2005 © BSI 2007 ISBN 978 0 580 59499 1 National foreword This British Standard is the UK implementation of EN ISO 10591:2005. It is identical with ISO 10591:2005. It supersedes BS EN ISO 10591:1998 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee B/547, Sealants for building and construction. A list of organizations represented on this committee can be obtained on request to its secretary. Additional information BS EN ISO 10591:2005 is a test method useful in the determination of adhesive/cohesive properties after immersion in water and one of the procedures used for classifying construction sealants within BS EN ISO 11600:2003. It is not suitable for testing sealants for water- retaining structures or for potable water systems. ISO 13638 is designed for the assessment of the long-term resistance of sealants to be permanently immersed in water.

The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10591 was prepared by Technical Committee ISO/TC 59, Building construction, Subcommittee SC 8, Jointing products. This second edition cancels and replaces the first edition (ISO 10591:1991), Clauses 2, 5, 6, and 7 of which have been technically revised.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 6927, Building construction Jointing products Sealants Vocabulary ISO 13640, Building construction Jointing products Specifications for test substrates 3 Terms and definitions For the purposes of this document, the 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 of the test specimens to water immersion under defined conditions, the test specimens are extended to rupture and the elongation at break recorded. 5 Apparatus 5.1 Substrate materials, used for the preparation of test specimens, are defined in ISO 13640, Specification for test substrates. The substrate materials shall be selected 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 (12 mm × 12 mm) 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.

For each substrate material, three test specimens shall be prepared. For each test specimen, two substrates (5.1) and two spacers (5.2) shall be assembled (see Figures 1 and 2) and set on the anti-adherent substrate (5.3). The instructions of the sealant manufacturer shall be followed concerning, for instance, whether a primer is to be used and the mixing procedure for multi-component sealants. The hollow volume formed by the substrates 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 to the contact surfaces of the substrates; c) the sealant surface shall be trimmed so that it is flush with the faces of the substrates and the spacers. The specimens shall be set on the edge of one of the substrates. The anti-adherent substrate shall be removed as soon as possible. The specimens shall be kept in this position to allow curing or optimum drying of the sealant. The spacers shall be maintained in place during conditioning. 7 Conditioning of test specimens 7.1 General The test specimens shall be conditioned either in accordance with method A (7.2) or method B (7.3), as agreed between the parties concerned. 7.2 Conditioning method A The test specimens shall be conditioned for 28 days at (23 ± 2) °C and (50 ± 5) % relative humidity. 7.3 Conditioning method B The test specimens shall be conditioned according to method A and shall then be subjected three times to the following storage cycle: a) three days in the oven (5.4) at (70 ± 2) °C; b) one day in distilled water (5.5) at (23 ± 2) °C; c) two days in the oven (5.4) at (70 ± 2) °C; d) one day in distilled water (5.5) at (23 ± 2) °C.

After conditioning according to method B, the test specimens shall be stored for 24 h at (23 ± 2) °C and (50 ± 5) % relative humidity before testing. NOTE Method B is a normal conditioning procedure using the influence of heat and water. It is not suitable for giving information on the durability of the sealant. 8 Test procedure After conditioning according to method A or method B, the spacers shall be removed. The test specimens shall be immersed for four days in water at a temperature of (23 ± 2) °C (5.6) and stored one day in air at (23 ± 2) °C and (50 ± 5) % relative humidity. The test specimens shall be placed in the tensile test machine (5.7) and extended at a rate of (5,5 ± 0,7) mm/min until break. The force/extension diagram shall be recorded. 9 Expression of results For each test specimen, the arithmetic mean of the three elongations to break shall be calculated and rounded to 5 %. Elongation (%) = (final width original width) / original width × 100 10 Test report The test report shall contain the following information a) test laboratorys name and date of testing; b) reference to this International Standard; c) name, type (chemical family) and colour of sealant; d) batch of sealant from which the test specimens were produced; e) the substrate materials used (see 5.1); f) the primer(s) used, if applicable; g) the conditioning method used; h) force/extension diagrams of the test specimens, i) the percentage elongation at break of each test specimen; j) the arithmetic mean of the three elongations at break; k) type of failure (adhesive or cohesive or mixed); l) any deviation from this International Standard.
