30、laved, for each test piece. Five fibre cement panels for each conditioning sequence with a length of approximately 150 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 sur
31、faces sometimes differ with respect to gloss, absorbency and strength. 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 fa
32、ilure of the substrate is the main finding of the preliminary substrate assessment, a suitable primer may be used for testing. 5.8.2 Plywood substrate, one uncoated plywood panel for each test piece. Five plywood panels for each conditioning sequence with a length of approximately 150 mm and a thick
33、ness of approximately 5,0 mm. The width is (50 0,5) mm. DIN EN 1372:2015-06 EN 1372:2015 (E) 7 NOTE Length and thickness 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 co
34、ntamination. 6.2 Sampling of adhesive Take a sample in accordance with EN ISO 15605 of the adhesive to be tested 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)
35、 C and (50 5) % relative humidity in accordance with ISO 554 for at least 24 h prior to use. 6.3.2 Fibre cement substrate Place the test panels (5.8.1) 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. A
36、t the end of this period, remove the test panels from the heating chamber 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 substrate Condition the materials at a standard atmosphere of (23 2) C and (50 5) % relative humidity in accord
37、ance with ISO 554 for at least 24 h prior to use. 6.4 Application of adhesive Place masking tape across one end of the upper side of each panel so as to leave 120 mm length to be coated with adhesive. Apply the adhesive under test across the full width of the panel using a notched trowel (5.1), held
38、 at an angle of approximately 60, steadily down the length of the panel to provide a uniform adhesive application. Remove the masking tape when the adhesive has been applied. NOTE When applying the adhesive, it is essential that the serrated blade is kept clean and free of adhesive build-up. Clean t
39、he blade regularly (no more than five panels to be prepared without 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
40、in accordance with EN 923), place the test covering (5.7) onto the coated panel (5.8) such that one end of the test covering is coincident with the end of the panel coated with the adhesive. Then align the test covering with the panel to produce a bonded area of 120 mm 50 mm (see Figure 4). DIN EN 1

42、itional pressure being applied. Remove any excess adhesive carefully from the edges of the test specimen with a clean tissue. Do not stack more than five test specimens. For coverings which show a tendency to curl after rolling, a dead load of (2,0 0,1) kg mass can be applied (3 0,5) h onto a stack
43、of five test specimens. The load is spread evenly over the whole surface thus ensuring a contact over the total bonded area of each test specimen. The procedure applied should be recorded in the test report see 10 j). 7 Conditioning of the test specimens After assembly, expose the test specimens to
44、the conditions as given in Table 1.

48、 peel force during separation N; b is width of test piece mm. Obtain the mean value of peel force (see Figure 6) ignoring the first and last 10 mm of the bond, i.e. taking into account only the middle 100 mm of the bond. NOTE The mean value of peel force can be determined by means of an integrator or by means of a graphical method, e.g. lay a transparent plate with the length axis drawn on it, onto the curve in such a way that the straight line is at rig
