25、uce firm and durable bonds between coverings and various substrates 4 Principle The adhesion is determined by measuring the shear strength under specified conditions before and after storing the bonds at 23 C/ 50 C under specified conditions.

28、rature between 20 C and 200 C according to EN ISO 9142. 5.4 Tensile testing machine, conforming to EN ISO 7500-1, class 1. 5.5 Primer, if applicable. 5.6 Test covering, five test pieces for each conditioning sequence of dimensions 60 mm 50 mm, the long side, running in the machine direction where th
29、is can be identified, and shall be taken at least 10 mm from the edge. 5.7 Substrate materials: Use either fibre cement or plywood as the substrate. 5.7.1 Fibre cement substrate, one uncoated fibre cement panel, fully compressed and autoclaved, for each test piece. Five fibre cement panels for each
30、conditioning sequence with a length of approximately 60 mm and a thickness of approximately 8,0 mm. The width is (50 0,5) mm. NOTE 1 Length and thickness are not critical. NOTE 2 Depending on the source of the fibre cement panels the surfaces sometimes differ with respect to gloss, absorbency and st
31、rength. In this case, it is important to do some preliminary assessment (i.e. peel tests) of the panels to identify the preferred side for testing. The preferred side will be called the upper side of the substrate in this standard. If failure of the substrate is the main finding of the preliminary a
32、ssessment, a suitable primer may be used for testing. 5.7.2 Plywood substrate, one uncoated plywood panel for each test piece. Five plywood panels for each conditioning sequence with a length of approximately 60 mm and a thickness of approximately 5,0 mm. The width is (50 0,5) mm. NOTE Length and th
33、ickness are not critical. 6 Preparation of the test specimens 6.1 Cleaning Ensure that all test coverings and substrate materials are clean and free from dust, loose particles or other contamination. 6.2 Sampling of adhesive Take a sample in accordance with EN ISO 15605 of the adhesive to be tested
34、and examine and prepare it in accordance with EN 1067. 6.3 Conditioning of materials 6.3.1 Adhesive and floor and wall coverings Condition the materials at a standard atmosphere of (23 2) C and (50 5) % relative humidity in accordance with ISO 554 for at least 24 h prior to use. 6.3.2 Fibre cement s
35、ubstrate Place the test panels (5.7.1) in a heating chamber (5.3) for 6 h at (80 2) C. Ensure that the test panels are spaced in such a way as to enable a free passage of air over them. At the end of this period, remove the test DIN EN 1373:2015-06 EN 1373:2015 (E) 7 panels from the heating chamber
36、and store for 48 h in a standard atmosphere of (23 2) C and (50 5) % relative humidity prior to use. 6.3.3 Plywood substrates Condition the materials at a standard atmosphere of (23 2) C and (50 5) % relative humidity in accordance with ISO 554 for at least 24 h prior to use. 6.4 Application of adhe
37、sive Place masking tape across one end of the upper side of each substrate so as to leave 20 mm length to be coated with adhesive. Apply the adhesive under test across the full width of the substrate using a notched trowel (5.1), held at an angle of approximately 60, steadily down the length of the
38、substrate to provide a uniform adhesive application. Remove the masking tape when the adhesive has been applied. When applying the adhesive, it is essential that the serrated blade is kept clean and free of adhesive build-up. Clean the blade regularly (no more than five substrates to be prepared wit
39、hout cleaning). In addition, regularly check the notch size and depth, especially where non-hardened steel blades are in use. 6.5 Bonding of the test covering After a time recommended by the adhesive manufacturer (i.e. minimum open time in accordance with EN 923), place the test covering (see 5.6) o
40、nto the coated panel (5.7) to provide an overlap of 20 mm such that the unbonded length protrudes from the edge of the panel coated with adhesive (see Figure 3). Dimensions in millimetres Figure 3 Shear test specimen Immediately after positioning the test covering, roll the test specimen with a roll
41、er (see 5.2) by passing forward and backward once along the test specimen without any additional pressure being applied. As the adhesive has not yet set it should be ensured that the overlapping area remains 20 mm x 50 mm without any shift during the subsequent treatments of the test coverings. Befo
42、re applying the roller it is advisable to support the unbonded area of the test covering by an additional panel of the same thickness in order to avoid tilting. To prevent the test covering from slipping caused by the roller an appropriate frame or mould for the substrate sheets in combination with
43、range spacers can be used for the covering. DIN EN 1373:2015-06 EN 1373:2015 (E) 8 For coverings which show a tendency to curl after rolling, a dead load of (2,0 0,1) kg mass can be applied for (3,0 0,5) h. The load is spread evenly over the whole surface thus ensuring a contact over the total bonde
44、d area of each test specimen. The procedure applied should be recorded in the test report see 10 i). 7 Conditioning of the test specimens After assembly, expose the test specimens to the conditions as given in Table 1.
