21、 International Standard specifies methods for the measurement of widths and lengths of cut light conveyor belts as described in ISO 21183-1 and specifies the tolerances on the dimensions.NOTE The widths and lengths of light conveyor belts are not standardized.2 Normative referencesThe following docu

23、 belts Part 1: Principal characteristics and applications3 WidthsWhen measured in accordance with 5.1, the difference between the measured width and the specified cut width shall not vary by more than the tolerance specified in Table 1.It is recommended that actual cut widths of belt be specified in
24、 incremental steps of 50 mm for cut widths up to 1 m, and in incremental steps of 100 mm for cut widths over 1 m.Table 1 Tolerances on cut widths of light conveyor beltsWidthmmFor belts containing materials with low moisture absorption (e.g. polyester)For belts with higher moisture absorption (e.g.

28、ment and verification of dimensions5.1 Determination of the cut width5.1.1 The measurements in 5.2 or 5.3 may be taken at the same time as the measurements in 5.1.5.1.2 Unroll the conveyor belt on a flat hard surface free from tension.5.1.3 Measure at three equidistant locations, throughout the leng
29、th of the belt and at right angles to the cut edges, the width of the conveyor belt to the nearest 0,5 mm, using a suitable linear measure (e.g. a steel tape).5.2 Determination of the length of an endless light conveyor belt5.2.1 Lay the conveyor belt flat, and free from tension.5.2.2 Mark the insid
30、e edge of the belt with an appropriate marker to indicate the point at which measurements begin (points A, B, C, D, etc., the last point being point X).Using a steel tape measure, make individual measurements along the flat part of the belt only (see Figure 1).Rotate the belt and make consecutive me
31、asurements along the flat part of the belt (BC;CD; etc.) (see Figure 1), continuing until the last measurement can be taken, e.g. XA .5.2.3 Calculate the endless length, le, of the belt as the sum of all the individual measurements minus the product of and the belt thickness,i.e. AB + BC + CD + XA a
32、 where a is the belt thickness.The calculation with the subtraction sum a is strictly correct only for conveyor belts with a symmetrical construction, i.e. with the neutral line in the belt middle. It is in most cases sufficiently exact also for conveyor belts with an asymmetrical construction. Howe
33、ver, short or thick conveyor belts with asymmetrical constructions may need a more precise calculation. The subtraction sum then becomes 2ai where ai is the distance between the neutral line and the inner belt surface (running surface). The value of aisshall be enquired of the belt manufacturer.(For
34、 symmetrical belt constructions, ai = a2and 2 ai becomes a.)DIN EN ISO 15147:2013-04 EN ISO 15147:2012 (E) 5 This value is the internal endless length of the belt.In cases where the method of measurement described above is not applicable, e.g. when the endless belt is very short, another suitable me
35、thod of measurement should be agreed between the belt user and supplier.A B Figure 1 Measurement of the length of an endless light conveyor belt5.3 Determination of the length of an open-ended light conveyor belt and of slab beltingDetermine the length of an open-ended light conveyor belt and of sla
36、b belting by employing any suitable mechanical, electromechanical or photoelectric means of linear measurement which does not exert any tension in to the conveyor belt and which is accurate to 01+ %of the recorded or designated length.With the end of the roll coinciding with the zero mark on the mea
37、suring surface, unroll the conveyor belt along the surface in such a manner that no tension is introduced. On reaching the limit of the surface, mark the roll by some suitable method on both edges to coincide with a known division of length. Re-roll the portion that has been measured. Lay out, free
38、from tension, a further portion of the unmeasured length and measure from the marked edges as before. Repeat this process until the end of the roll appears. Measure the final length and record the overall length as the sum of the individual measurements taken.DIN EN ISO 15147:2013-04 EN ISO 15147:2012 (E) 6
