24、3 iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for whi
25、ch 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 m
26、atters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Stan
27、dard 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Internatio
28、nal Standard ISO 9047 was prepared by Technical Committee ISO/TC 59, Building construction, Subcommittee SC 8, Jointing products.

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
32、document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

33、he purposes of this International Standard, the terms and definitions given in ISO 6927 apply. 4Principle 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
34、 specimens are examined for evidence of loss of adhesion and cohesion. 5Apparatus 5.1Substrate materials, used for the preparation of test specimens, shall be as defined in ISO 13640. Select the substrate material(s) from mortar and/or anodized aluminium and/or glass. Other substrate materials may b
35、e 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 adhes
36、ion shall be the same as those shown in Figures 1 and 2. 5.2Spacers, for the preparation of the test specimens, of cross-section with anti-adherent surface (see Figures 1 and 2). 5.3Anti-adherent substrate, for the preparation of test specimens, e.g. polyethylene (PE) film, preferably according to t

40、mens Bring the sealant and the substrate material to a temperature of . For each substrate prepare three test specimens. For each specimen, assemble two substrates (5.1) and two spacers (5.2) (see Figure 1) and set up on the anti- adherent substrate (5.3). Follow the instructions of the sealant manu
41、facturer concerning, for instance, whether a primer is to be used and the mixing procedure for multi-component sealants. Fill the hollow volume formed by the substrates with the sealant. Take the following precautions: a)avoid the formation of air bubbles; b)press the sealant to the contact surfaces
42、 of the substrates; c)trim the sealant surface so that it is flush with the faces of the substrates and the spacers. Set the test specimens at the edge of one of the supports. Remove the anti-adherent substrate as soon as possible. Rest the specimens in this position to allow curing or optimum dryin

Maintain the spacers in place during conditioning. 7Conditioning of test specimens 7.1Conditioning method A Condition the test specimens for 28 days at and relative humidity. 7.2Conditioning method B First condition the test specimens according to method A and subsequently subject
44、them three times to the following storage cycle: a)3 days in the oven (5.4) at ; b)1 day in distilled water (5.6) at ; c)2 days in the oven (5.4) at ; d)1 day in distilled water (5.6) at .

The speed of extension and compression used in the test procedure is . The
47、 amplitude of testing is or or , or any amplitude agreed by the parties concerned. Subject the test specimens to the following extension/compression cycles at the required amplitude. First week Day 1: Place the test specimens in the refrigerated enclosure (5.5) at . After extend the test specimens i
48、n the test machine (5.7) to the required amplitude. Maintain the extension at for . Day 2: Release the extension. Place the test specimens in the oven (5.4) at . After compress the test specimen in the test machine (5.7) to the required amplitude. Maintain the compression at for . Day 3: Release the
49、 compression and follow the procedure of Day 1. Day 4: Follow the procedure of Day 2. Day 5 to 7: Release the compression, store at and relative humidity without applying any mechanical force. Second week Repeat the procedure of the first week. After the test specimens have been submitted to the above cycles, they are examined for loss of cohesion or adhesion.
