19、ization for Standardization) 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 establish

20、ed 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

21、 International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pu

22、blication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such paten

23、t rights. ISO 583 was prepared by Technical Committee ISO/TC 41, Pulleys and belts (including veebelts), Subcommittee SC 3, Conveyer belts. This third edition of ISO 583 cancels and replaces ISO 583-1:1999, of which it constitutes a technical revision. It also incorporates the Technical Corrigendum,

24、 ISO 583-1:1999/Cor.1:2006. EN ISO 583:20071Conveyor belts with a textile carcass Total belt thickness and thickness of constitutive elements Test methods 1 Scope This International Standard specifies test methods for the determination of total belt thickness and the thickness of constitutive elemen

25、ts of conveyor belts having a textile carcass. The constitutive elements include the covers, the carcass and interlayers, i.e. the material between adjoining plies. This International Standard is not suitable or valid for light conveyor belts as described in ISO 21183-11. 2 Determination of total be

26、lt thickness 2.1 Apparatus The apparatus shall consist of a flat, rigid baseplate, on which the test piece rests, and a gauge having a flat circular foot, 10 mm in diameter, by means of which a specified pressure is applied to the test piece. The gauge shall be capable of measuring to at least 0,1 m

27、m. The pressure applied shall be (22 5) kPa for materials with a hardness equal to or greater than 35 IRHD; otherwise, the pressure shall be (10 2) kPa. NOTE The masses needed to give these specified pressures using a 10 mm diameter foot are 176 g and 80 g, respectively. 2.2 Test piece Either test p

28、iece 1 or test piece 2, according to the following, shall be used. Test piece 1: cut a rectangular piece of full-width belt, designated as dimension L, with a length of 50 mm, as shown in Figure 1. Dimensions in millimetres Figure 1 Test piece 1 (rectangular) EN ISO 583:20072 Test piece 2: cut a wed

29、ge-shaped piece of full-width belt, designated as dimension L, as shown in Figure 2. Dimensions in millimetres Figure 2 Test piece 2 (wedge-shaped) 2.3 Measurement points The measurement points shall be spaced equidistantly along the long axis of the test piece (i.e. the belt width), as shown in Fig

30、ure 3. Dimensions in millimetres Figure 3 Measurement points Determine the minimum number of measurement points, x, according to the width of the belt, L, in accordance with Table 2.

32、 as the total belt thickness in millimetres, to the nearest 0,1 mm. 3 Determination of thickness of covers 3.1 General The thickness of the covers can be obtained by two methods, the choice of one or the other method depending on whether or not the covers can be removed completely from the carcass.

33、3.2 Method used when covers can be removed completely from carcass 3.2.1 Principle The thickness of a test piece is measured at a number of points, according to belt width, both before and after each of the covers has been removed. The cover thickness is calculated by subtraction. 3.2.2 Apparatus Th

34、e apparatus shall be in accordance with 2.1. 3.2.3 Test piece Test piece 1, in accordance with 2.2 and Figure 1, shall be used. 3.2.4 Measurement points The measurement points shall be in accordance with 2.3. 3.2.5 Procedure Measure the total thickness, d, of the test piece at each of the measuremen

35、t points, in accordance with 2.4. Remove the top cover completely, then remeasure the thickness of the test piece, d1, at the same measurement points. EN ISO 583:20074 Then remove the bottom cover completely and measure the thickness of the test piece, d2, at the same measurement points. See Figure

Figure 4 Interlayer thickness (plied fabric belt) Protective fabrics embedded in the covers, and which do not form an integral part of the textile carcass, shall be regarded as part of the covers and should be removed with them. Other non-lo

38、ad bearing yarns, which are an integral part of the carcass, shall normally be regarded as part of the carcass, unless otherwise agreed between manufacturer and purchaser. In the latter case, full details shall be included in the test report. 3.2.6 Expression of results Calculate the thickness, e1,

EN ISO 583:200753.3 Method used when covers cannot be removed completely from carcass 3.3.1 Principle The thickness of each cover is mea

41、sured directly on a cut edge of unstripped belt by means of an optical micrometer or travelling microscope. 3.3.2 Apparatus Optical micrometer or travelling microscope incorporating a scale graduated in divisions of 0,1 mm. 3.3.3 Test piece Cut the test piece in accordance with 2.2 (test piece 1 or

42、test piece 2). If the conveyor belt is of solid woven construction, test piece 2 shall be used. 3.3.4 Measurement points The measurement points shall be in accordance with 2.3. If test piece 2 is used, take measurements along line DC shown in Figure 2. 3.3.5 Procedure Using the optical micrometer or

43、 travelling microscope (3.3.2), measure the distance between the surface of the belting and the top of the nearest fabric knuckle (see Figure 5) at each of the measurement points specified in 2.3. Ensure that the graduated scale of the optical micrometer or travelling microscope is in physical conta

44、ct with the test piece to avoid errors of parallax. With certain colours of cover material, difficulty can be experienced in determining the outline of the fabric knuckles. In these cases, the textile fabric may be identified with a colour stain. Protective fabrics embedded in the covers, and which

45、do not form an integral part of the textile carcass, shall be regarded as part of the covers and excluded from the measurements. Other non-load bearing yarns, which are an integral part of the carcass, shall normally be regarded as part of the carcass, unless otherwise agreed between manufacturer an

46、d purchaser. In the latter case, full details shall be included in the test report.
