20、 (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 which a technical com
21、mittee 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 electrot
22、echnical 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 mem
23、ber 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 identify
24、ing any or all such patent rights. ISO 11432 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 11432:1993), Clauses 5, 6 and 7 of which have been technically revised. EN ISO 1143
25、2:20051Building construction Sealants Determination of resistance to compression 1 Scope This International Standard specifies a method for the determination of the resistance to compression of sealants used in joints in building construction. 2 Normative references The following referenced document
26、s are indispensable for the application of this document. 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, B
27、uilding 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, in which the sealant to be tested is adhered to two parallel substrate surfaces, are compressed by
28、 a defined percentage of the original width and the force recorded. 5 Apparatus 5.1 Substrate materials, used for the preparation of test specimens, are defined in ISO 13640, Specification for test substrates. The materials shall be selected from mortar and/or anodized aluminium and/or glass. Other
29、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 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 o
30、f 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-sections (12 mm 12 mm) with anti-adherent surface. 5.3 Anti-adherent substrate, for the preparation of test specimens, e.g. polyethylene (PE) film, preferably according to
31、 the advice of the sealant manufacturer. 5.4 Ventilated convection-type oven, capable of operating at (70 2) C for conditioning according to method B. 5.5 Container, for water immersion of the specimen for conditioning according to method B. 5.6 Tensile test machine, capable of compressing the test
32、specimens at a rate of (5,5 0,7) mm/min. EN ISO 11432:20052 6 Preparation of test specimens The sealant and the test substrate shall be brought to (23 2) C. For each substrate material, three test specimens shall be prepared. For each test specimen, two substrates (5.1) and two spacers (5.2) shall b
33、e 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 sh
34、all 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
35、spacers. The test specimens shall be set on the edge of one of the supports and the anti-adherent substrate shall be removed as soon as possible. The test specimens shall be kept in this position to allow curing or optimum drying of the sealant. The spacers shall be maintained in place during condit
36、ioning. 7 Conditioning of test specimens 7.1 General The test specimens shall be conditioned either according to method A (see 7.2) or method B (see 7.3). 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
37、 B First the test specimens shall be conditioned according to method A and subsequently 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 distill
38、ed water (5.5) at (23 2) C. This cycle may be carried out alternatively in the sequence: c), d), a), b). After conditioning according to method B, the test specimens shall be stored for a further period of 24 h at (23 2) C and (50 5) % relative humidity before testing. NOTE Conditioning method B is
39、a normal conditioning procedure using the influence of heat and water. It is not intended to give information on the durability of the sealant. EN ISO 11432:200538 Test procedure The test shall be carried out at (23 2) C and (50 5) % relative humidity. The spacers (5.2) shall be removed. The test sp
40、ecimens shall be placed in the tensile test machine (5.6) and compressed at a rate of (5,5 0,7) mm/min to 75 % or 80 % of the initial width, or by any other percentage as agreed by the parties concerned. The following table gives the correspondence in millimetres of the percentage compression for a
41、test specimen of 12 mm initial width. Table 1 Correspondence of compression values original width 12 mm Compressed width relative to the original width % Compression % Width after compression mm 75 25 9,0 80 20 9,6 The force, expressed in newtons, required for the appropriate compression shall be re
42、corded. 9 Expression of results For each test specimen, the secant compression modulus shall be calculated, for the chosen compression amplitude, rounded to 0,01 N/mm2, using the equation: Secant compression modulus = Force at chosen compression (expressed in N)/initial cross-section area (expressed
43、 in mm2) The arithmetic mean of the three secant compression modulus values shall be calculated, rounded to 0,01 N/mm2. 10 Test report The test report shall contain the following information: a) the test laboratorys name and the date of testing; b) a reference to this International Standard; c) name
44、, type (chemical family) and colour of sealant; d) batch of sealant from which the test specimens were produced; e) substrate material used; f) the primer used, if applicable; g) the method of conditioning (see Clause 7); h) the percentage compression (see Clause 8); i) the secant compression modulu
45、s of each test specimen (N/mm2); j) the arithmetic mean of the three secant compression moduls; k) any deviations from this International Standard.
