18、 national standards shall be withdrawn at the latest by October 2000. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s

19、), see informative Annex ZA, which is an integral part of this standard.

STD-BSI BS EN 1082-3-ENGL 2000 W lb2Ybb7 0877378 319 Page 3 EN 1082-3:2000 Introduction This test is based on the impact penetration test in EN 41

21、2 “Protective aprons for use with hand knives“. It differs in that the blade holding block and blade weigh 110 g rather than 1000 g. The sample support is also changed to suit the testing of fabric, leather, and other materials. The test is designed particularly to assess the stab resistance of mate

22、rials for gloves and arm guards. The test is also suitable for assessing gloves exposed to severe abrasion and cutting threats such as motorcyclists gloves, working gloves for handling concrete blocks or razor wire, or protective leggings and trousers for refuse collectors. Severe abrasion is a proc

23、ess involving multiple cuts and this test is a good indicator of abrasion resistance of the whole thickness of a material or sequence of materials. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienc

24、ed people, for whose guidance it has been prepared. The apparatus described should only be used by competent persons and requires safeguards to prevent, as far as is reasonably practicable, injury to the operator and other persons. 1 Scope This European Standard contains the specification for an imp

25、act cut test for use on fabric, leather and other materials. 2 Normative references This European Standard incorporates by dated reference, provisions from other publications. These normative references are cited at appropriate places in the text and are listed hereafter. For a dated reference, subs

26、equent amendments to or revisions of it, apply to this Standard only when incorporated in it by amendment or revision.

When it is cited as a test method in a specific product standard that Standard shall co

29、ntain the necessary information to permit the application of this European Standard to the particular products.

30、d of preparation and pre-treatment, if any, and the permitted size range of samples; 3) details of the clamping and stretching method to be used with the samples; 4) the energy( of impacts to be used in the test; 5) the orientations of blade impacts relative to a specified axis of the samples; 6) th

31、e number of tests to be performed, and where they are to be located; 7) details of any deviations from the method described in this European Standard; 8) the content of the test report to be provided; 9) the performance requirements for the product, and associated levels;. The performance required s

32、hall be given as a mean penetration through the sample of not more than XX mm when tested according to YYY; 10) the area of the product that is to meet the requirements.

33、 BS EN L082-3-ENGL ZOO0 Lb24bb9 0877379 255 Page 4 EN 1082-312000 5 Test apparatus and procedures 5.1 Cut testing apparatus 5.1.1 Principle The leather or fabric gloves or materials are tested by impacts of standard knife blades held in a guided falling block. The component parts of a possible desig

34、n of a test apparatus are shown in figure 1. The design of the stand is not normative. Details of the test sample support, falling block and test blade are given in subsequent clauses. Design details such as the means of allowing removal of the block and test blade after impact, and necessary safety

35、 guards are not shown. 5.1.2 Blade holding block The blade holding block is shown in figure 2. The test blade shall be held in the block so that it protrudes by (55 f 5) mm. The position of the blade tip shall be offset by the distance /4 which is (8 f 1) mm from the centre line of the block which s

36、hall pass through the centre of gravity of the block. The centre of gravity of the block and blade shall be (100 f 10) mm above the blade tip level. The mass of the block with test blade shall be (110 f 5) g. The block shall be held in its initial position by an electromagnet. The block shall have f

37、our sliders made of polytetrafluorethylene or similar material, which guide its drop down the guide rods. There shall be 0,5 mm to 1,5 mm clearance between the sliders and the guide rods. The heights from which the block is released shall be set so that the appropriate energy of impact is achieved.

38、5.1.3 The test blade The test blade shall have the profile and dimensions as shown in figure 3. It shall be made of cold-forged stainless steel with a degree of hardness greater than 45 HRC. Its edge shall be straight and sharp. Before every penetration test the blade shall conform to the specificat

39、ion. NOTE: After machine grinding, the blade edge should be made smooth and sharp by hand finishing on an oilstone. Blades may be re-sharpened after use. When fabrics and leathers are tested re-sharpening is not required ater every test. The calibration material results reveal the need for re-sharpe

40、ning. 5.1.4 Sample support Figure 4 illustrates the apparatus described below. The material sample or glove is supported on a horizontal arm which ends in a circular anvil with a hole in it which the knife enters during the test. It has been found convenient to make the support from mild steel. The

41、circular metal anvil shall be (50 * 1) mm in diameter and have a vertical height of approximately 60 mm. The top surface shall be machined to be domed with a radius of curvature of (200 * 5) mm. The anvil shall have a slot cut in it at its centre. The slot shall be (3,5 f 0,051) mm wide and (23 f 0,

42、2) mm long. The ends shall be semi- circular. The slot shall be vertical and pass through the anvil. The anvil may be machined out from below so that the centre of the anvil is not less than 7 mm thick. The anvil shall be attached to a horizontal arm such that the axis of the arm is at (45 2 5)“ to

43、the long axis of the slot. The arm shall be attached to the anvil so that its top surface is (30 f 2) mm below the centre of the top of the anvil. The arm shall be (15 2 2) mm wide and (35 f 5) mm deep. The arm shall be attached to a rigid support such that there is at least 180 mm clearance below i

44、t, and the arm has an unobstructed length of at least 150 mm. The sample support shall be firmly attached to the base plate of the apparatus which shall be provided with a hole at least 50 mm wide directly under the anvil so that a weight suspended on a string can be clipped to the lower side of the

45、 sample on the support. STD-BSI BS EN 1082-3-ENGL 2000 D Lb2qbbS 0877380 T77 = Page 5 EN 1082-3:2000 5.1.5 Preparation of samples Samples shall be prepared so that they have a shape and dimensions suitable for the test. Flat materials should be sewn, stapled, welded, or in some other way, joined to

46、form a tube. The tube should be at least 100 mm in length, but not so long that its length impedes positioning of the sample as required in 5.2.2. The tube shall have a circular diameter of (100 f 20) mm. Knitted materials should be prepared so that the area to be tested is representa- tive of the m

47、aterial as used in products. The sample may need to be stabilised by a line of stretchable over-lock stitches around its edge to prevent the knitted structure breaking down. Samples that consist of gloves or arm guards may be suitable to test complete. Very stiff products shall be cut and have their

48、 cut edges stabilised, so that they can be positioned as required in 5.2.2. If washing and dry cleaning pre-treatments are to be conducted. Intact products, or on large material specimens, should be pre-treated before samples are prepared. 5.1.6 Mounting a sample The sample is slid onto the anvil an

49、d arm so that the area to be tested lies over the anvil. A weight of (1 O00 i 50) g is clipped to the dependant side of the sample pulling on it with a force of 10 N. The sample should be smoothed out over the anvil. By twisting the sample on the anvil cuts can be made parallel to the long axis of the sample, transversely across the sample and at any angle between these orientations. 5.2 Procedures 5.2.1 Setting up the apparatus Ensure the guide rods are vertical (i 2 rnrn in 1 rn), and the blade holding block runs freely on the guide rods fr
