This part of ISO 7622 specifies a method for the determination of the elongation of steel cords constituting the carcass of conveyor belts, when subjected to a force corresponding to 10 % and 60 % of the specified tensile strength. It applies exclusively to conveyor belts with a steel carcass. NOTE A method for the determination of tensile strength is specified in ISO 7622-2.

This International Standard specifies the maximum electrical resistance of a conveyor belt and the corresponding test method. The test is intended to ensure that the belt is sufficiently conductive to avoid the accumulation of electrical static charge which can be developed during service use. This International Standard is not suitable or applicable to light conveyor belts as described in ISO 21183-1[1], the static electrical properties of which are measured by ISO 21178[2]. The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. 3 Specification The electrical resistance of the conveyor belt when tested in accordance with the method described in Clause 4 shall not exceed 3 × 108 Ω (300 MΩ). Lower values may be specified for special applications. 4 Test method 4.1 Principle An electric current of specified voltage is passed via electrodes through a suitably prepared test piece taken from the belt. 4.2 Materials and apparatus 4.2.1 Sheet of insulating material, a little larger than the test piece. 4.2.2 Two cylindrical and coaxial brass electrodes, the base of one being circular and the other annular. The dimensions and masses are given in Figure 1. The bases of these electrodes shall be machined flat and polished. A flexible insulated wire shall be connected to each electrode. 4.2.3 Ohmmeter (resistance-measuring instrument), with a range up to 1010 Ω and accurate to ±5 %. 4.2.4 Source of direct current, adjustable to 1000 V, and not permitting a current greater than 10 mA or causing an energy dissipation of more than 1 W in the test piece. The source of current may be either an accumulator or a rectified, stabilized AC-power supply. 1 Licensee=University of Alberta/5966844001, User=sharabiani, shahramfs

This International Standard specifies the temperature, humidity and time conditions used for the conditioning and testing of all types of conveyor belt, irrespective of whether they have plastics or rubber covers. It also specifies the requirements for the time interval to be observed between production and testing of conveyor belt test pieces. Special conditions applicable to a particular test or material or simulating a particular climatic environment are not included.

This International Standard specifies a static test method for measuring the strength of a conveyor belt mechanical fastening; the mechanical joints can be either of the type employing a connecting rod or of a type which does not employ a connecting rod. This International Standard does not cover vulcanized joints. This International Standard is neither applicable to nor valid for light conveyor belts, as described in ISO 21183-1. NOTE The purpose of the test specified in this International Standard is to eliminate mechanical fastenings of insufficient static strength. It is intended to establish a dynamic test at a later date.
