    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

    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
