DIN EN 16653:2015-05 EN 16653:2015 (E) 4 1 Scope This Euro

18、pean Standard specifies a method for the determination of the resistance of the seams of rubber or plastic-coated fabrics against tearing out a needle perpendicular to the stitching direction. This resistance is characterized by determining the stitch tear force. 2 Normative references The following

19、 documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 2231, Rubber-

22、this document, the following terms and definitions apply. 3.1 stitch tear resistance resistance to pull a needle from a sample perpendicular to the stitching direction 3.2 stitch tear force stitch tear resistance, recorded as the maximum tearing force 3.3 stitch tear strength stitch tear force divid

23、ed by the thickness 4 Test apparatus and materials The following test apparatus and materials shall be used: 4.1 CRE machine. Metrological confirmation system of the tensile-testing machine shall be in accordance with EN ISO 10012. The constant-rate-of-extension (CRE) machine shall have the general

24、characteristics given in 4.1.1 to 4.1.4. DIN EN 16653:2015-05 EN 16653:2015 (E) 5 4.1.1 The tensile-testing machine shall be provided with means for indicating or recording the force applied to the test specimen. Under conditions of use, the accuracy of the apparatus shall be class 1 of EN ISO 7500-

25、1. The error of the indicated or recorded maximum force at any point in the range in which the machine is used shall not exceed 1 %. 4.1.2 If a class 2 tensile-testing machine according to EN ISO 7500-1 is to be used, this shall be stated in the test report. 4.1.3 If recording of force is obtained b

26、y means of data acquisition boards and software, the frequency of data collection shall be at least eight per second. 4.1.4 The machine shall be capable of constant rate of extension of (100 10) mm/min. 4.2 Needle. Either a smooth needle of stainless steel having a diameter of (1,0 0,1) mm and a con

27、ical tip or a corresponding piece of spring steel wire having the same diameter, also made of stainless steel and having a conical tip. 4.3 Clamping device. As an example, Figure 1 shows a schematic view of a clamping device. The bearing bushes for the needle shall be parallel and adjustable such th

28、at they can be set in accordance with the thickness of the test specimen. The clamping device shall be provided with a suitable safety device which prevents the needle from jumping out.

29、mp Figure 1 Schematic view of a clamping device 5 Sampling and conditioning The test specimens to be tested are sampled in the warp and weft directions. For each direction, five test specimens shall be sampled. The test specimens consist of strips with a length of (50 1) mm and a width of (20 1) mm.

30、 All test specimens shall be conditioned for at least 24 h prior to testing in accordance with EN ISO 2231. The final result shall be based on test specimens of the same type only, and the type shall be indicated in the test report. DIN EN 16653:2015-05 EN 16653:2015 (E) 7 6 Test method The test is

31、carried out after conditioning in a standard atmosphere in accordance with EN ISO 2231. The thickness of the test specimen shall be measured in accordance with EN ISO 2286-3. A needle having a diameter of 1 mm (see 4.2) is inserted into the test specimen 5 mm from the edge in the centre of the narro

32、w side (see Figure 1), as perpendicularly as possible, by means of a template. Prior to this, the test specimen shall not have been pierced or punched in any manner. The needle, which is now held (fixed) inside the test specimen, is placed into the clamping device (see 4.3). The distance between the

33、 spacers shall be adjusted such that they just barely touch the test specimen. The lower end of the test specimen is clamped into the lower jaw (shown as a scissor clamp in Figure 1). The test specimen is elongated at 100 mm/min. Record the maximum force, in newtons, which occurs while the needle is

34、 being torn out (see Figure 2).

35、ean of the highest individual values (Fmax) of the five test specimens, given for each direction, expressed in N and rounded to the nearest 0,5 N. 7.2 Stitch tear strength If required, the stitch tear strength, expressed in N/mm, is calculated as follows: maxStitch tear strength =Fdwhere Fmaxis the

36、maximum stitch tear force, in newtons; d is the thickness of the test specimen, in millimetres. 8 Test report The test report shall contain the following information: a) a reference to this test method; b) the complete marking of the tested sample, including commercially available types, codes, colours, condition, etc.; c) the date of the test; d) the standard atmosphere used; e) the results in accordance with Clause 7: stitch tear force (7.1) and, if required, stitch tear strength (7.2); f) any deviation from the given procedure.
