This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by August 2006, and conflicting national standards shall be withdrawn at the latest by August 2006. According to the CEN/CENELEC Internal Regu

EN 14959:2006 (E) 4 1 Scope This European Standard specifies a method for determining the resistance to fraying of touch and close fasteners. 2 Normative references The following referenced documents
16、 are indispensable for the application of this European Standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12241, Touch and close fasteners Method for closure prior to washing an

18、ut along its longitudinal axis, sewn on a fabric, on three of its edges (as shown in Figure 1), then assembled with its male or female counterpart (as shown in Figure 2), using the roller specified in EN 12241, then washed according to the specified procedure described in EN ISO 6330. 4 Apparatus 4.
19、1 Long pair of scissors to cut the samples at a length of 50 mm in one stroke. 4.2 Loading fabric, polyester/cotton (50 %/50 %) 130 g/m2. 4.3 Washing machine as specified in EN ISO 6330. 4.4 A metal roller as specified in EN 12241. 5 Test specimen Cut a specimen of male or female tape, to be tested
20、for resistance to fraying, of 50 mm length. Cut a specimen of the male or female counterpart of same width, of 70 mm length. Cut a specimen of loading fabric, of 75 mm length and of width equal to the width of the sample of tape to be tested plus 25 mm. EN 14959:2006 (E) 5 6 Conditioning Condition t
21、he test specimens for a minimum of 24 h in accordance with the standard temperate atmosphere for testing as specified in EN ISO 139. The closing, the drying, the evaluation of the test specimens for resistance to fraying, shall also take place under these conditions. 7 Procedure Cut the specimen of
22、male or female tape to be tested, on a length of 50 mm, taking care to cut at an angle of 90 to its longitudinal axis. Cut the specimen along its longitudinal axis, in one stroke, with a long pair of scissors (4.1). Once the cutting is completed, check the absence of loose filaments, along the longi
23、tudinal cut edge. In case of the presence of loose fibres, the sample has to be eliminated and the sampling repeated. The three cut edges have to be free of loose elements. Sew this specimen on the fabric on the two longitudinal edges and one transversal edge, as shown in Figure 1, following the dis
24、continuous lines. Complete the sewing with 3 stitches per cm at 1,5 mm from the edge of the tape, using a needle number 0,80, with a polyester yarn 30 tex. In order to simulate the closure in usage, position the counterpart of the male or female tape, on top of the tape to be tested (see Figure 1).
25、Use the metal roller (4.4) to close the samples. The roller will be chosen according to the effective width of the tape to be tested after it had been cut along its longitudinal axis. Traverse the metal roller along the closure in one direction then immediately reverse in the other direction. Put th
26、e combined specimen in the loading bag, in order to protect it during washing. Put the loading bag in the washing machine (4.3), then complete the washing, according to the specified cycle in EN ISO 6330. After washing, allow the specimen to dry 24 h in the standard temperate atmosphere defined in E
27、N ISO 139. Separate and close the touch and close fastener, by hand, five times. The fraying will be evaluated by counting the number of loose filaments still attached to the four edges of the tape. 8 Test report The test report shall contain the following information: a) number and date of this Eur
28、opean Standard, i.e. EN 14959:2006; b) date of the test; c) identification of the touch and close fastener; d) any deviation from this European Standard and any incident likely to have affected the results. e) result of the evaluation for fraying.
