20、 adherend and one flexible adherend when tested under specified conditions of preparation and testing. NOTE The use the floating roller produces more constant numerical data than other peel methods, but it should not be expected that the flexible adherend will conform to the surface of the roller. S

It shall be provided with a suitable self-aligning grip to hold the test specimen. The jaws of this grip shall f
28、irmly engage the outer 25 mm of the end of the flexible adherend. The grip and attachments shall be so constructed that they will move into alignment with the test specimen as soon as the force is applied, so that the flexible member of the test specimen will coincide with the direction of the appli
29、ed pull through the centre line of the grip assembly. The machine shall be autographic, giving a chart that can be read in terms of millimetres of crosshead movement as one coordinate and applied force as the other coordinate. All equipment shall be calibrated regularly. It is recommended that equip
30、ment should be essentially free of inertial forces during use. The machine shall permit the measurement and recording of the applied force with an accuracy of 1 %. 4.2 Peel test fixture, for supporting the test specimen (see Figure 1). The fixture shall be attached to one of the cross-arms of testin
31、g machine (4.1). The 25 mm diameter rollers on the test fixture shall roll freely. The angle determined by the rollers and the use of dual roller bearings are critical and the rollers shall therefore be carefully maintained. 1) See for instance ISO 5893:2002, Rubber and plastics test equipment Tensi

33、st specimens 5.1 Test specimens of the dimensions shown in Figure 2 may be prepared individually or cut from bonded panels. Laminated test panels, or individual test specimens, shall consist of two adherends properly prepared and bonded together. 5.2 The adherends and the surface treatment shall be
34、in accordance with the intended application and process. The adhesive shall be applied in accordance with the manufacturers recommendations to obtain an optimum bond with minimum of variations. NOTE Direct comparison of different adhesives can be made only when test specimen construction, adherend m
35、aterials and dimension and test conditions are identical. DIN EN 1464:2010-06 EN 1464:2010 (E) 7 5.3 The thickness of the flexible adherend shall be (0,5 0,02) mm and that of the rigid adherend shall be (2,5 0,1) mm in the case of metals, or thicker if other adherends are used in order the reduce th
36、e deformation of the rigid adherend. 5.4 If the test specimens are cut from the bonded panels (see Figure 2) it shall not be deleterious to the bond. The width shall be either: a) 25 mm (the preferred width); or b) any other convenient width, provided that the test equipment is suitably adapted and
37、the width is stated in the test report. NOTE The method of cutting the test specimens is dependent upon the adherend and adhesive compositions. Milling and band-sawing are two methods commonly used for this purpose. 5.5 The unbounded end of the flexible adherend shall be bent perpendicular to the ri
38、gid adherend for clamping in the grip of the testing machine. 5.6 The number of specimens to be tested shall be as specified in the material specification or, if not so specified, shall be not less than five.

40、the peel test fixture (4.2) as shown in Figure 1, with the unbounded end of the flexible adherend gripped in the jaw of the testing machine (4.1). Peel the specimen at a constant crosshead separation rate of (100 5) mm/min, unless otherwise specified. If the rigid adherend bends or is distorted DIN
41、EN 1464:2010-06 EN 1464:2010 (E) 8 during the test, it is recommended that the specimen be redesigned with a rigid adherend stiff enough to ensure even peeling. During the peel test, make an autographic recording of force versus crosshead movement (force versus distance peeled) over a length of a le
42、ast 115 mm of the bond line disregarding the first 25 mm of peel. Disregard the results if failure occurs outside the peeling zone as defined in Figure 1. 7.2 Wet peel test Insert the test specimen into the peel test fixture (4.2) as shown in Figure 1, with the unbounded end of the flexible adherend
43、 gripped in the jaw of the testing machine (4.1). Peel the specimen at a constant crosshead separation rate of (100 5) mm/min, unless otherwise specified. If the rigid adherend bends or is distorted during the test, it is recommended that the specimen be redesigned with a rigid adherend stiff enough
44、 to ensure even peeling. Stop the crosshead after peeling about 75 mm of the bonded length. Then apply several drops of water containing a wetting agent (for example 0,5 % to 1,0 % of a detergent) to the crack opening. After the application of this liquid the peeling process shall be immediately com
45、menced. The test shall be continued until the complete sample is peeled. An autographic recording of force versus crosshead movement (force versus distance peeled) shall be made. Disregard the results if failure occurs outside the peeling zone as defined in Figure 1. 8 Expression of results Determin
46、e from the autographic curve, for at least 115 mm of peeling (disregarding the first 25 mm and the last 25 mm), the average peeling resistance, in newtons per millimetre (N/mm) of the test specimen width, required to separate the adherends. The average force may be determined from the curve by one o
47、f the following methods: a) a planimeter; b) a gravimetric method, as follows: Cut out the area of the chard paper surrounded by the curve and the base line (abscissa) and weigh it. Determine the area by dividing its mass by the previously determine mass per surface area of the chart paper. Divide t
48、he area thus found by the length of the base line (corresponding to 80 mm peeling length), to obtain the average height of the curve (and hence the average peeling force); c) by drawing the best straight line through the peeling curve using a straight edge; d) by any other method such as computer as
49、sisted. Also record the maximum and minimum forces for each individual specimen. 9 Test report The test report shall include the following information: a) a reference to this European Standard; DIN EN 1464:2010-06 EN 1464:2010 (E) 9 b) identification of the adhesive tested, including type, source, manufacturers code number, batch or lot number, form, etc.; c) identification of adherends, including material, thickness, width and surface preparation; d) description of the bonding process, in
