This document supersedes EN ISO 583-1:1999. According to the CEN/CENELEC Internal Regula

20、lands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. Endorsement notice The text of ISO 583:2007 has been approved by CEN as EN ISO 583:2007 without any modifications. 1 Scope This International Standard specifies test methods for the determina

21、tion of total belt thickness and the thickness of constitutive elements 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 con

22、veyor belts as described in ISO 21183-11. 2 Determination of total belt 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

23、test piece. The gauge shall be capable of measuring to at least 0,1 mm. 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 diamete

24、r foot are 176 g and 80 g, respectively. 2.2 Test piece Either test piece 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

25、1 Test piece 1 (rectangular) 4 EN ISO 583:2007 (E) DIN EN ISO 583:2008-03 Test piece 2: cut a wedge-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

26、spaced equidistantly along the long axis of the test piece (i.e. the belt width), as shown in Figure 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. 5 EN ISO 583:2007 (E

28、2.5 Expression of results Calculate the arithmetic mean of the individual measurements taken according to 2.4 and express this 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 meth

29、ods, the choice of one or the other method depending on whether or not the covers can be removed completely from the carcass. 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, b

30、oth before and after each of the covers has been removed. The cover thickness is calculated by subtraction. 3.2.2 Apparatus The 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 point

31、s shall be in accordance with 2.3. 3.2.5 Procedure Measure the total thickness, d, of the test piece at each of the measurement 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. 6 EN ISO 583:2007 (E) D

32、IN EN ISO 583:2008-03 Then remove the bottom cover completely and measure the thickness of the test piece, d2, at the same measurement points. See Figure 4.

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 ma

35、nufacturer 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, of the top cover at each of the measurement points: 11edd=Calculate the thickness, e2, of the bottom cover at each of the measurement points: 212e

Calculate the arithmetic mean of the individual measurements and express the cover thicknesses in millimetres, to th

37、e nearest 0,1 mm. 7 EN ISO 583:2007 (E) DIN EN ISO 583:2008-03 3.3 Method used when covers cannot be removed completely from carcass 3.3.1 Principle The thickness of each cover is measured directly on a cut edge of unstripped belt by means of an optical micrometer or travelling microscope. 3.3.2 App

38、aratus 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 test piece 2). If the conveyor belt is of solid woven construction, test piece 2 shall be used. 3.3.4 Measurement poi

39、nts 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 travelling microscope (3.3.2), measure the distance between the surface of the belting and the top of the nearest fa

40、bric 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 contact with the test piece to avoid errors of parallax. With certain colours of cover material, difficulty can be experie

41、nced 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 do not form an integral part of the textile carcass, shall be regarded as part of the covers and excluded from the me

42、asurements. 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 and purchaser. In the latter case, full details shall be included in the test report. Key d total thickness e1thickness

47、etermination of thickness of interlayer 5.1 General The thickness of an interlayer (i.e. the elastomeric material between textile fabric layers in a belt of multiply fabric construction) can be obtained using two methods, the choice of one or the other method depending on whether or not the elastome

48、r can be completely separated from the fabric plies. 5.2 Method used when elastomeric material in interlayer can be removed completely from adjacent fabric ply 5.2.1 Principle Thickness measurements are taken at a number of points across the belt width, after the covers have been removed, and again

49、after separation of the fabric and elastomeric layers. The thicknesses of the interlayers are obtained by subtraction. 9 EN ISO 583:2007 (E) DIN EN ISO 583:2008-03 5.2.2 Apparatus The apparatus shall be in accordance with 2.1. 5.2.3 Test piece Test piece 1, in accordance with 2.2 and Figure 1, shall be used. 5.2.4 Measurement points The measurement points shall be in accordance with 2.3. 5.2.5 Procedure Measure carcass thickness d2of the test piece at each of the measurement points specified in 2.3, using the pressure in accordance
