1.1These test methods (and references) cover the procedures for evaluating the physical properties of flat conveyor belting. Performance criteria for belting will not be detailed here, but can be found through the RMA (Rubber Manufacturers Association) Conveyor and Elevator Belt Handbook, ANSI (American National Standards Institute), various governmental authorities, and the International Organization for Standardization (ISO). Belting for conveying and elevating materials generally is designated and defined as follows:
1.1.1Heavy Duty Conveyor—A heavy duty belt is defined as belting designed for bulk haulage of materials, such as stone, crushed rock, sand, metals ores, coal, wood chips, etc., and has a carcass strength (design) substantial enough to withstand conveyor system tensions of 160 PIW and above.
Note 1:PIW is an abbreviation for pounds per inch of width commonly used in the conveyor belt industry.
1.1.2Light Duty Conveyor—A light duty belt is defined as belting designed for conveying a variety of lower weight materials, packages, industrial and electronic goods, and food products. These belts often are shorter in length and width, with less overall thickness than heavy duty belting, and are generally used in conveyor systems with tensions less than 160 PIW.
1.1.3General Description—Belting can have elastomeric coverings on one side, both sides, or neither side depending upon the specific application requirements. Belt coverings are comprised of various synthetic or natural rubber polymers, PVC, or other elastomeric materials, dependent upon application or customer requirements. The load bearing member(s) of most belting is generally a woven or interwoven carcass of synthetic or natural fibers such as, but not limited to, polyester, nylon, polyaramid, cotton, as well as steel (cable/cord type or woven mesh).
1.1.4The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.2This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
