16、ion of the tear resistance of sealants used in joints in building construction.2 Normative referenceThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated r

17、eferences, the latest edition of the referenced document (including any amendments) applies.ISO 6927, Buildings and civil engineering works Sealants Vocabulary3 Terms and definitionsFor the purposes of this document, the terms and definitions given in ISO 6927 apply.4 PrincipleTest specimens are pre

18、pared such that the sealant to be tested adheres to two parallel contact surfaces. An incision is realized in the sealant to a defined length. The test specimens are extended to a defined width and this extension is maintained under defined conditions. Any tear propagation is noted.5 Apparatus5.1 Su

19、bstrate materials, used for the preparation of test specimens as defined in ISO 13640. 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 1. Test

20、 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 12 mm) with anti-adherent surface. For the preparation of test specimens see Figure 1.5.3 Anti-adherent sub

21、strate, which is for the preparation of the test specimens, for example, polyethylene (PE) film, preferably according to the advice of the sealant manufacturer.5.4 Tensile test machine, capable of extending the test specimens at a rate of (5,5 0,7) mm/min.5.5 Ventilated convection-type oven, capable

22、 of being maintained at (70 2) C for conditioning according to method B (see 7.3).5.6 Container, immersing test specimens in distilled water for conditioning according to method B (see 7.3).

24、bstrates shall be brought to (23 2) C. Three test specimens shall be prepared. For each specimen two substrates (5.1) and two spacers (5.2) shall be assembled (see Figure 1) and set on the anti-adherent substrate (5.3).The instructions of the sealant manufacturer concerning, for instance, whether a

25、primer is to be used and the mixing procedure for multi-component sealants shall be followed. The hollow volume formed by the substrates and the spacers shall be filled with the sealant.The following precautions shall be taken:a) formation of air bubbles shall be avoided;b) sealant shall be pressed

26、on the inner surfaces of the substrates;c) sealant surface shall be tooled so that it is flushed with the faces of the substrates and spacers.The test specimens shall be set on the edge of one of the supports. The anti-adherent substrate shall be removed as soon as possible. The specimens shall be p

27、laced 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 specimens7.1 GeneralThe test specimens shall be conditioned either in accordance with method A (see 7.2) or method B (see 7.3), as agreed betwe

28、en the parties concerned.7.2 Method AThe test specimens shall be conditioned for 28 d at (23 2) C and (50 10) % relative humidity.7.3 Method BThe 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

29、 (5.5) at (70 2) C;b) one day in distilled water (5.6) at (23 2) C;c) two days in the oven (5.5) at (70 2) C;d) one day in distilled water (5.6) at (23 2) C.Alternatively, this cycle may be carried out in the order c), d), a), b).2 ISO 2016 All rights reservedBS ISO 19863:2016ISO 19863:2016(E)After

30、conditioning according to method B, the test specimens shall be stored for 24 h at (23 2) C and (50 10) % 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 sealan

31、t.8 Test procedureThe test procedure shall be carried out at a temperature of (232) C.The spacers (5.2) for the preparation of the test specimens shall be removed.An incision in the sealant of the test specimens shall be created with either the 6 mm or 9 mm knife blade (5.7) through the complete thi

32、ckness of the sealant (12 mm). Figure 2 indicates the position of the incision, in the sealant.The test specimens shall be placed in the tensile test machine (5.4) at and extended at a rate of (5,5 0,7) mm/min by 25 % or 40 %, or 50 % of the original width (to 15 mm, 16,8 mm, and 18 mm respectively)

33、, or to any other width as agreed between the parties concerned (see Figure 3). The default defined width is twice the movement capability tested in ISO 9047 for qualification in ISO 11600 and ISO 11618. The initial length of the incision shall be measured and recorded to the nearest 0,5 mm.The sepa

34、rators (5.8) shall be used to maintain the elongation for 24 h.The final length of the incision shall be measured using a suitable measuring device capable of reading to 0,5 mm with the separators maintained in position after 24 hours or a suitable time as agreed amongst the parties (5.9). Measure a

35、nd record the maximum length of the incision with the separators remaining in place.9 Expression of resultsFor each test specimen, the tear propagation shall be calculated using the formula:Tear propagation (mm) =final length of the incision (mm) initial length of the incision (mm)The results shall

36、be expressed to the nearest 0,5mm.The mean of the three results shall be calculated and expressed to the nearest 0,5mm.10 Test reportThe test report shall contain the following information:a) test laboratorys name and date of test;b) a reference to this International Standard, ISO 19863;c) name, typ
