Standards for light conveyor belts define what exactly a “light conveyor belt” is due to their exclusion from many other standards that deal with conveyor belts. Compensating for this exclusion, light conveyor belt standards offer alternative test methods which are applicable, allowing for the determination of dimensions, tensile strength, electrical resistance, coefficients of friction and other characteristics vital to a reliable and properly functioning light conveyor belt.
ISO 15147:2012 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.
This document specifies test methods for determining the electrical resistances of light conveyor belts according to ISO 21183 1. The resistances are surface resistance, volume resistance perpendicular to the belt plane, and longitudinal and transverse volume resistance parallel to the belt plane. This document also specifies two test methods for determining the surface resistivity and the volume resistivity.
ISO 21179:2013 specifies a test method for the determination of the electrostatic field generated by a running light conveyor belt according to ISO 21183-1.
ISo 21181:2013 specifies a test method for the determination of the relaxed elastic modulus of light conveyor belts according to ISO 21183-1 or other conveyor belts where ISO 9856 is not applicable.
ISO 21182:2013 specifies test methods for determining the dynamic and static coefficients of friction for light conveyor belts according to ISO 21183-1.
ISO 21183-1:2005 describes the principal characteristics and applications of light conveyor belts. This description is necessary either for limiting the validity of certain standards to light conveyor belts or for excluding light conveyor belts from the validity of certain standards.
This document establishes a list of equivalent terms relating to light conveyor belts. NOTE In addition to terms used in the three official ISO languages (English, French and Russian), this document gives the equivalent terms in German, Spanish, Italian and Japanese; these are published under the responsibility of the member bodies for Germany (DIN), Spain (AENOR), Italy (UNI) and Japanese (JISC). However, only the terms given in the official languages can be considered as ISO terms.
Lays down the main dimensions of belts, idlers and pulleys used for the various types of light duty belt conveyors for loose bulk materials. Does not apply to either portable and mobile conveyors, or mining conveyors.
