Association, and supports essential requirements of the EU Directive 89/686/EEC For relationship with EU Directives, see informative Annex ZA, which is an integral part of this standard 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of an identical text or by endorsement, at the latest by March 1996, and conflicting national standards shall be withdrawn at the latest by March 1996 According to the CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland,

This European Standard specifies a test method for measuring the puncture resistance of protective clothing or materials used for these products The puncture resistance is expressed as the maximum force required to push a spike with a specified speed through the test specimens 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 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 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 Test specimens 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 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 two 10 mm minimum thick steel plates, each having a (20 ± 0,5) mm diameter hole in the centre and four clamping bolts, as shown in Figure NOTE Gripping 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 described in ISO 2231, 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 ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ Take four representative test specimens from the sample, each 50 mm minimum diameter, so that the specimens fit between the bolt holes of the clamps 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 travel of at least 100 mm; — a constant rate of compression of (100 ± 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 © BSI 11-1999 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 not comply with the dimensions of Figure 1, the test spike shall be discarded 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 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 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 the remaining specimens Record for each test the maximum force (in newtons) needed to penetrate the specimen 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 EN 863:1995 Test report The test report shall include the following information: — the number and the date of this European Standard; — all details necessary for the identification of the sample tested; Dimensions in millimetres Steel 60 HRC — the results obtained for each test specimen; — the mean value in newtons; — any deviation from the procedure outlined in this standard ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ Figure — Test spike Dimensions in

essential requirements of the EU Directive 89/686/EEC WARNING: Other requirements and other EU Directives may be applicable to the product(s) falling within the scope of this standard The clauses of this standard are likely to support requirements of 3.3 of Annex II “Protection against physical injury” of EU Directive 89/686/EEC Compliance with these clauses of this standard provides one means of
