23、dization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to

24、 be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Stan

25、dards are drafted in accordance with the rules given in the ISO/IEC Directives, Part3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies cast

27、oduction Although textiles, composites, leather, rubbers and reinforced materials may resist cutting by sharp edges in different ways, a test method for evaluating the resistance to cut of materials in protective clothing needs to be applicable to all materials. The test described in this Internatio

28、nal 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. The performance of protective clothing materials may be classified using the numerical values obtained from this

29、 test. 1 Scope This International Standard specifies a cut test method, and related calculations, for use on materials and assemblies designed for protective clothing. The test determines resistance to cutting by sharp edges, such as knives, sheet metal parts, swarf, glass, bladed tools and castings

30、. This 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

31、 include 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 publica

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

When it is cited as a test method in a materials or product standard, that standard shall contain the necessary information to permit the applicat

36、ion of ISO13997 to the particular product. The standard citing ISO13997 shall include at least the following: a) a normative reference to ISO13997; b) a description of the samples to be tested, their method of preparation, and pretreatment, if any, and the permitted size and orientation range of the

37、 specimens prepared for the samples; c) details of the clamping and stretching method to be used with the specimens; d) the number of tests to be performed; e) details of any deviation from the method described in ISO13997; f) details of the format and content of the test report to be provided; g) t

38、he performance requirements for the product and associated “level”. The performance required shall be given as the minimum cutting force. Information and guidance on using ISO13997 in a product standard are given inAnnex A. 5 Sampling 5.1 Specimens shall be taken from regions of the sample product r

39、epresentative of the range of construction present in protective areas. Specimens shall be taken from positions representative of the variations in the quality of the material present.ENISO 13997:1999 2 BSI 04-2000 5.2 Specimens from woven, knitted and other orientated materials shall be prepared so

40、 that test cuts are made at an angle of (45 10) to the machine direction of the material. Unoriented materials, or those in which the machine direction is uncertain, shall be tested in two directions at 45 to each other. Specimens from particular materials or products may be tested at other orientat

41、ions specified by a standard citing ISO13997. 5.3 Unless otherwise specified, specimen dimensions shall not be less than25mm 100mm, with the intended cut orientation at 90 to the long axis. The smallest specimen on which single cuts are made shall not be less than25mm 25mm. 5.4 Specimens shall be co

42、nditioned in accordance with ISO139. Testing shall be carried out in the conditioning environment or within5min of withdrawing the specimens from the conditioning environment. 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

43、measured in a machine in which a sharp blade is drawn across a specimen. The cuts are achieved in blade movements of3mmto50mm length when a range of forces are applied to the blade normal to the specimen surface. The cut resistance of a sample material is expressed as the cutting force that is requi

44、red to be applied to a blade of standard sharpness to just cut through the material in a20mm blade stroke. The value of the cutting force may be used to classify materials. Any apparatus can be used that can maintain a constant force between the cutting edge and the specimen, and can accurately meas

45、ure the distance the blade travels to cut through the specimen. Annex B (informative) describes instrumentation that meets these requirements. 6.2 Test apparatus The apparatus shall have the following components. 6.2.1 Rigid framework that supports the constituent parts when a force of up to200N is

46、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 specimen holder during operation of the machine such that the force between the cutting edge and the specimen is constant 5%. The force shall be v

47、ariable between1,0N and200N. The force may be applied to the blade holder or 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 0,5)mm. The length of the mounting area shall be gr

48、eater than110mm and the width across the curvature shall be greater than or equal to32mm. The mounting of the specimen holder shall provide for multiple cuts to be made on single specimens at minimum intervals of10mm. 6.2.4 Blades, made of stainless steel with a hardness greater than45HRC. Blades sh

49、all be (1,0 0,5)mm thick and ground to a bevel width of (2,5 0,2) mm along a straight edge. This is an included angle of approximately22 at the cutting edge. Blades shall have a cutting edge length greater than65mm and blades shall be more than18mm wide. 1) 6.2.5 Blade holder, capable of holding the blade rigidly and with minimum distortion so that (12,0 0,5)mm of the blade width is exposed. The blade shall be held so that it is orientated across the curvature of the specimen holder with the plane of the blade at (90 2
