24、ethod gives a measure of the suitability of a plastic or rubber floor or wall covering/adhesive combination by monitoring dimensional changes during defined conditioning sequences when bonded to a specific substrate. 5 Apparatus and materials 5.1 Notched trowel (for the shape of the notch, see Figur

25、e 1) with dimensions a, b and c specified by the adhesive manufacturer. BS EN 1903:2015EN 1903:2015 (E) 5 Key a notch depth b notch width c notch distance Figure 1 Shape of notches of notched trowels 5.2 Roller, of width (60 5) mm, diameter (90 5) mm and total mass (3,50 0,05) kg with a handle at 90

26、 to the axis (as an example, see Figure 2). Dimensions in millimetres Figure 2 Roller NOTE The length of the handle is not critical and can be used for setting the total mass. 5.3 Heating chamber, ventilated and adjustable to a temperature between 20 C and 200 C according to EN ISO 9142. 5.4 Primer,

27、 if applicable. BS EN 1903:2015EN 1903:2015 (E) 6 5.5 Test covering, three test pieces for each combination with adhesive dimensions of (250 5) mm (250 5) mm or (300 5) mm (300 5) mm. 5.6 Substrate, one uncoated fibre cement panel, fully compressed and autoclaved, of a minimum thickness of approxima

28、tely 8,0 mm for each test piece. Dimensions shall not be greater than 50 mm longer than the distance between the datum points, i.e. each datum point shall not be greater than (25 1) mm from the outer edge (see Figure 3). NOTE 1 The thickness is not critical. NOTE 2 Depending on the source of the fib

29、re cement panels the surfaces can 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 th

31、ing to the nearest 0,01 mm over a length of either 200 mm or 250 mm, e.g. an elongation meter. 5.8 Adhesives, for fixing gauge studs to the covering surface if required by the measuring method. BS EN 1903:2015EN 1903:2015 (E) 7 6 Preparation of test specimens 6.1 Conditioning of fibre cement substra

32、te Place the test panels (5.6) 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 panels from the heating oven and store in a standard atmosphere of (23 2) C and

33、 (50 5) % relative humidity for at least 48 h prior to use. 6.2 Conditioning of test covering 6.2.1 Room temperature storage Condition all test pieces (5.5) in a standard atmosphere of (23 2) C and (50 5) % relative humidity for at least 24 h prior to use. 6.2.2 Elevated temperature pre-treatment Pl

34、ace the test pieces (5.5) on a firm horizontal substrate (5.6) and heat for 6 h in a heating chamber (5.3) at (80 2) C. Ensure that the test pieces and substrate 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 pieces and supports from

35、 the heating chamber and store for 48 h in a standard atmosphere of (23 2) C and (50 5) % relative humidity prior to use. The pre-treatment will release any stresses in the covering so that it is in a relaxed state when the actual test is commenced. The pre-treatment of the test coverings may be run

36、 together with the conditioning of the substrate (6.2). In most cases a more practical assessment is required. Pre-conditioning of the floor or wall covering materials at elevated temperature (6.2.2) may not be regarded as necessary. If knowledge of dimensional changes after this pre-treatment is re

37、quired, dimensions should be measured as given in 6.5 before and after the pre-treatment. 6.3 Sampling and conditioning 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. Condition the adhesive in a standard a

38、tmosphere of (23 2) C and (50 5) % relative humidity for at least 24 h before making the test specimens, in accordance with ISO 554. 6.4 Datum points 6.4.1 Fixing of gauge positions Using the appropriate adhesive, fix the gauge studs in four positions, each being (25 1) mm from the outer edge of the

39、 covering (see Figure 3). 6.4.2 Edge to edge measurements Test specimens shall be marked at positions (25 1) mm from each edge. 6.5 Initial measurements of dimensions prior to bonding Measure the dimension of each test piece along the two datum lines LL and MM parallel to its grain, when this can be

40、 identified, (longitudinally) and the two datum lines PP and QQ at right angles to these lines (transversely). Record as measurement A. BS EN 1903:2015EN 1903:2015 (E) 8 Depending on the type of measuring device to be used, the measurements may be made from edge to edge or from scribe datum marks as

41、 described previously (see Figure 3). 6.6 Preparation of bonded test specimens 6.6.1 Cleaning Ensure that all floor coverings and fibre cement panels are clean and free from dust, loose particles or other contamination. NOTE For unbonded control test specimens, if required, test pieces are laid dire

42、ctly onto the fibre cement panels. 6.6.2 Application of adhesive Apply the adhesive (5.4) to the upper side of the substrate (5.6) using a notched trowel (5.1) held at an angle of approximately 60 to the slab, comb the adhesive to provide a uniform application. Hold the trowel at a right angle to on

43、e edge of the slab and draw it across the slab parallel to that edge in a straight line. 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 three fibre cement panels to be prepared without cleaning)

44、. In addition, regularly check the notch size and depth, especially where non-hardened steel blades are in use. 6.6.3 Bonding After a time recommended by the adhesive manufacturer (i.e. minimum open time in accordance with EN 923), place a test piece on the prepared panel ensuring that the machine d

45、irection of the test piece is at right angles to the adhesive ridges. Smooth with light hand pressure and then roll with a roller (5.2) starting at one edge rolling up and down and gradually moving across the panel ensuring all areas are rolled. Repeat the rolling in a direction at right angles to t

46、he first rolling. NOTE For coverings which show a tendency to curl after rolling, a dead load of (5,0 0,25) kg mass can be applied (3,0 0,5) h onto the test specimens. The load is spread evenly over the whole surface thus ensuring a contact over the total bonded area. 7 Procedure 7.1 Preconditioning

47、 Condition test specimens in a standard atmosphere of (23 2) C and (50 5) % relative humidity in accordance with ISO 554 for seven days. Measure all dimensions and record all results as measurement B. 7.2 Conditioning cycle (accelerated ageing) Store both unbonded and bonded test specimens at 50 C f

48、or 13 days in heating chamber (5.3), ensuring that the panels are horizontal and separated to allow good air circulation. Remove and post condition in a standard atmosphere for 24 h. Re-measure and record as measurement C1. 7.3 Subsequent cycles Repeat the cycle in 7.2 giving measurements C2, C3, et

49、c. At least two cycles shall be completed, but further cycles may be carried out if required. BS EN 1903:2015EN 1903:2015 (E) 9 8 Evaluation and expression of results For each datum line on each test piece measure the following dimensional changes: a) change during conditioning (B to A); b) change after one cycle (C1to A); c) change after further cycles (C2to A, C3to A, etc.). For both the unbonded control test specimens and the bonded test specimens, tabulate the dimensional changes, i.
