The puncture resista
23、nce is expressed as the maximum force required to push a spike with a specified speed through the test specimens. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate plac

EN 10002-2 Metallic materials - Tensile testing - Part 2: Vervication of the force measuring system of the tmsik testing machines Rubber- or plastics-coated fabrics - conditioning and testing IS0 2231 : 1989 Standard atmospheres for 3 Test specimens Take four representative test spec
26、imens from the sample, each 50 mm minimum diameter, so that the specimens fit between the bolt holes of the clamps. 4 Test method 4.1 Apparatus 4.1.1 Tensile testing machine In this method a tensile testing machine type CRE as defined in EN 10002-2 is used and shall be capable of: - a vertical trave
27、l of at least 100 mm; - a constant rate of compression of (100 f 10) mm/min; - a recording apparatus for the force and deformation. 4.1.2 Test spike The test spike shall be made of steel, with a minimum hardness of 60 HRC and shall have the dimensions and the characteristics as shown in figure 1. Pa
28、ge 3 EN 863 : 1995 The test spike shall be checked by an optical enlargement after every 500 tests or at least once a year. When testing materials which wear out the test spike, the optical checks should be done more frequently. If this test shows that the test spike dimensions do not comply with th
29、e dimensions of figure 1, the test spike shall be discarded. NOTE. The control of the dimensions of the test spike is important. It is recommended that every test laboratory maintains an internal reference material to do regular checks on the results of the testing. 4.1.3 Clamps The clamping rings h
30、ave to prevent slippage during the test. They consist of two 10 mm minimum thick steel plates, each having a (20 f 0,5) mm diameter hole in the centre and four clamping bolts, as shown in figure 2. NOTE. Gripping aids can be used if necessary to prevent slippage or reduce damaging of the specimen. 4
31、.2 Conditioning The specimens shall be conditioned and the test shall be conducted in the standard atmosphere as described in IS0 2231, i.e. at a relative humidity of ,(65 f 5) % and a temperature of (20 f 2) OC. Conditioning at a specified relative humidity may be omitted if it can be shown that th
32、e results for the type of material under test were not affected. 4.3 Procedure Secure the specimen between the clamping rings with the outer surface exposed to the test spike, tighten the nuts sufficiently to ensure no slippage of, or damage to, the specimen. Place the specimen and the clamping ring
33、s in the tensile testing machine. Advance the spike on to and through the specimen at a rate of (100 f 10) mm/min. If the spike fails to penetrate after a movement of 25 mm after contact with the specimens, the test is terminated. This shall be referred to in the test report. Repeat the procedure on
34、 the remaining specimens. Record for each test the maximum force (in newtons) needed to penetrate the specimen. 5 Calculation of results Calculate the arithmetical mean of the maximum force (in newtons) needed to puncture the four test specimens, rounded to the nearest value.
