23、S0 13997:1999 Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject
24、 for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC)
25、on ali matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internatio
26、nal Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 13997 was prepared by Technical Committee ISO/TC 94, Personal safety - Protective clothing and equipment, Subcommittee SC 13, Protective clothing. Annexes A and B of this international Sta

28、 materials in protective clothing needs to be applicable to all materials. The test described in this International Standard provides a method that allows calculations of the downwards (normal) force required to cause a blade drawn across the sample for a fixed distance to cut through the specimen.
29、The performance of protective clothing materials may be classified using the numerical values obtained from this test. iV STD.BSI BS EN IS0 13997-ENGL 1799 D Lb24bb7 CiO3L 030 m EN IS0 13997:1999 Protective clothing - Mechanical properties - Determination of resistance to cutting by sharp objects 1
30、Scope This International Standard specifies a cut test method, and related calculations, for use on materials and as- semblies designed for protective clothing. The test determines resistance to cutting by sharp edges, such as knives, sheet metal parts, swaif, glass, bladed tools and castings. This
31、test does not provide data on the resistance to penetration by pointed objects such as needles and thorns. The test described in this International Standard is not considered suitable for testing materials made from chain mail and metal plates. The text of this International Standard does not includ
32、e provisions for the safeguard of the operator. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, this publication do
33、 not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Membe
34、rs of IS0 and IEC maintain registers of currently valid International Standards.

35、 has occurred when the blade edge first contacts the conducting material below the test specimen 3.2 cutting force calculated force that would be required to be applied to a blade of standard sharpness to just cut through a material in a blade stroke of length 20 mm 3.3 cutting stroke length distanc
36、e the cutting edge travels before cut-through occurs 4 Requirements This International Standard describes a method of test for materials and products. When it is cited as a test method in a materials or product standard, that standard shall contain the necessary information to permit the application
37、 of IS0 13997 to the particular product. The standard citing IS0 13997 shall include at least the following: a) a normative reference to IS0 i 3997; 1 STD-BSI BS EN IS0 13997-ENGL details of the clamping and stretching method to be used with the specimens; d) the number of tests to be performed; e)
38、details of any deviation from the method described in IS0 13997; f) details of the format and content of the test report to be provided; g) the performance requirements for the product and associated “level“. The performance required shall be given as the minimum cutting force. Information and guida
39、nce on using IS0 13997 in a product standard are given in annex A. 5 Sampling 5.1 Specimens shall be taken from regions of the sample product representative of the range of construction present in protective areas. Specimens shall be taken from positions representative of the variations in the quali
40、ty of the material present. 5.2 Specimens from woven, knitted and other orientated materials shall be prepared so that test cuts are made at an angle of (45 f 10) to the machine direction of the material. Unoriented materials, or those in which the machine direction is uncertain, shall be tested in
41、two directions at 45“ to each other. Specimens from particular materials or products may be tested at other orientations specified by a standard citing IS0 13997. 5.3 Unless otherwise specified, specimen dimensions shall not be less than 25 mm x 100 mm, with the intended cut orientation at 90“ to th
42、e long axis. The smallest specimen on which single cuts are made shall not be less than 25 mm x 25 mm. 5.4 Specimens shall be conditioned in accordance with IS0 139. Testing shall be carried out in the conditioning environment or within 5 min of withdrawing the specimens from the conditioning enviro
43、nment. 6 Test method 6.1 Principle The cut resistance of a material is its ability to resist being cut through by a blade. This is measured in a machine in which a sharp blade is drawn across a specimen. The cuts are achieved in blade movements of 3 mm to 50 mm length when a range of forces are appl
44、ied to the blade normal to the specimen surface. The cut resistance of a sample material is expressed as the cutting force that is required to be applied to a blade of standard sharpness to just cut through the material in a 20 mm blade stroke. The value of the cutting force may be used to classify
45、materials. Any apparatus can be used that can maintain a constant force between the cutting edge and the specimen, and can accurately measure the distance the blade travels to cut through the specimen. Annex B (informative) describes instrumentation that meets these requirements. 6.2 Test apparatus
46、The apparatus shall have the following components. 6.2.1 Rigid framework that supports the constituent parts when a force of up to 200 N is exerted between the cutting edge and the specimen. 6.2.2 Force application system to move the specimen holder towards the blade, or the blade towards the specim
47、en holder during operation of the machine such that the force between the cutting edge and the specimen is constant f 5 YO. 2 STD-BSI BS EN IS0 L3997-ENGL 1999 Lb24bb9 0809332 903 H EN IS0 13997:1999 The force shall be variable between 1,0 N and 200 N. The force may be applied to the blade holder or
48、 to the specimen holder. 6.2.3 Specimen holder, with surface made of metal on which the specimen is mounted. The specimen mounting area shall be curved with a radius of (38 I 0,5) mm. The length of the mounting area shall be greater than 110 mm and the width across the curvature shall be greater tha
49、n or equal to 32 mm. The mounting of the specimen holder shall provide for multiple cuts to be made on single specimens at minimum intervals of 10 mm. 6.2.4 Blades, made of stainless steel with a hardness greater than 45 HRC. Blades shall be (1 ,O i 0,5) mm thick and ground to a bevel width of (2,5 I 0,2) mm along a straight edge. This is an included angle of approximately 22“ at the cutting edge. Blades shall have a cutting edge length greater than 65 mm and blades shall be more than 18 mm wide.) 6.2.5 Blade holder, capable of holding
