26、asteners to opening and closing cycles in order to simulate use. The touch-and-close fasteners subjected to these cycles will be used in subsequent physical tests intended to measure the residual mechanical strength characteristics. 2 Normative references This European Standard incorporates by dated

29、widths of tapes and the effective width of a closure. 3 Principle An apparatus is used to open and close a touch-and-close fastener of a specific width a specified number of times. 4 Apparatus The apparatus comprises two drums mounted one on top of the other (see Figure 1): the bottom drum is 110 mm

30、 wide and 160 mm in diameter; the top drum has the same width and is 162,5 mm in diameter. The two drums shall have a slot to receive the end of the test specimens, and a tensioning device (see Figure 2). The top drum shall be free to rotate. It shall be fitted with variable weight, according to the

31、 total effective width of the touch-and-close fastener, in order to apply a constant load. The bottom drum shall rotate at a constant speed of (60 5) min 1 . The direction of rotation shall be reversed every 30 s. The rotation of the bottom drum is transmitted to the top drum by the physical contact

32、 of the touch-and- close fasteners. The apparatus shall be fitted with a counter which records the number of rotations of the bottom drum regardless of the direction of rotation. A example of a suitable apparatus is given in Annex A. 5 Test specimens Take test specimens of male and female tapes of t

33、he same overall width. Cut consecutive test specimens long enough to be fixed into the drum slots. It is recommended that the drums be covered in accordance with Table 1, in order to ensure good repeatability of the simulation method.

The test shall be carried out in this atmosphere. 7 Proce

35、dure 7.1 Determine the overall width of the tapes in accordance with prEN 12240. From Table 1, determine the number of tapes with which to load the apparatus. Determine the effective width of the fastener in accordance with prEN 12240. 7.2 Calculate the total effective width as a function of the num

36、ber of test specimens to be fixed to the drums. Apply a mass of (1 0,1) kg per centimetre of total effective width, to the top drum 7.3 Position and secure the female tape(s) on the bottom drum and the male tape(s) to the top drum. Ensure that the two tapes are correctly aligned and in permanent con

37、tact with the whole surface of the drums 7.4 If it becomes difficult to keep the test specimens correctly aligned, or to keep them in contact with the drums, use double-sided adhesive tape to fix the backs of the tapes to the drums. 7.5 Pretension the tapes as shown in Figure A.2. Introduce the free

38、 ends of the tapes in the slots see A.1b) view CC. Apply a pretension to the specimen by positioning the metal rods see A.2. on the loose tape, so forming a loop. Evenly tighten the specimen on both upper and lower rolls by using the revolving slots until the metal rods are as close as possible to t

39、he rolls. Remove the metal rods. Then tighten the tapes completely. Secure the revolving slots by using the screws. 7.6 Start up the apparatus for the specified number of opening and closing cycles. 7.7 At the end of the test, remove the test specimens from the apparatus and remove the parts that ha

40、ve not been subjected to opening and closing cycles. 8 Test report Report the following information: reference to this European Standard; identification of the touch-and-close fastener tapes; date of the test; any deviation from this European Standard, and any incident likely to have affected the re
