This European Standard has been prepared under a Mandate given to CEN by
19、the European Commission and the European Free Trade Association, and supports essential requirements of the EU Directive89/686/EEC. For relationship with EU Directives, seeinformative Annex ZA, which is an integral partof this standard. This European Standard shall be given the status of a national
20、standard, either by publication of an identical text or by endorsement, at the latest by March1996,and conflicting national standards shall be withdrawn at the latest by March1996.

The puncture resistance is expressed as the maximum force required to push a spike with
24、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 places in the text and the publications are listed hereafter. For dated
25、references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 10002-2, Metallic materials Tensile testing Part
26、2: Verification of the force measuring system of the tensile testing machines. ISO 2231:1989, Rubber- or plastics-coated fabrics Standard atmospheres for conditioning and testing. 3 Test specimens Take four representative test specimens from the sample, each50mm minimum diameter, so that the specime
27、ns 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 EN10002-2is used and shall be capable of: a vertical travel of at least100mm; a constant rate of compression of(100 10)mm/min; a reco
28、rding apparatus for the force and deformation. 4.1.2 Test spike The test spike shall be made of steel, with a minimum hardness of60HRC and shall have the dimensions and the characteristics as shown in Figure 1. The test spike shall be checked by an optical enlargement after every500tests or at least
29、 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 the dimensions of Figure 1, the test spike shall be discarded. NOTEThe control of the dimensions of the test spi
30、ke 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 have to prevent slippage during the test. They consist of two10mm minimum thick steel plates, each having a (20 0
31、,5)mm diameter hole in the centre and four clamping bolts, as shown in Figure 2. NOTEGripping aids can be used if necessary to prevent slippage or reduce damaging of the specimen. 4.2 Conditioning The specimens shall be conditioned and the test shall be conducted in the standard atmosphere as descri
32、bed in ISO2231,i.e.at a relative humidity of(65 5)%and a temperature of (20 2) C. Conditioning at a specified relative humidity may be omitted if it can be shown that the results for the type of material under test were not affected. 4.3 Procedure Secure the specimen between the clamping rings with
33、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 rings in the tensile testing machine. Advance the spike on to and through the specimen at a rate of (100 10)mm/min. If the spike fails
34、to penetrate after a movement of25mm after contact with the specimens, the test is terminated. This shall be referred to in the test report. Repeat the procedure on the remaining specimens. Record for each test the maximum force (innewtons) needed to penetrate the specimen. 5 Calculation of results
35、Calculate the arithmetical mean of the maximum force (in newtons) needed to puncture the four test specimens, rounded to the nearest value.EN863:1995 4 BSI 11-1999 6 Test report The test report shall include the following information: the number and the date of this European Standard; all details ne
