【国外标准】 Standard Classification for Rubber Compounding Materials—Recycled Vulcanizate Rubber

4.1 Recycled vulcanizate particulate rubber is important in rubber compounding. It allows the rubber compounder to add a certain percentage of rubber filler back into its parent or similar compounds or to use the material as substitute or stand alone compound. Its use may lower compound costs or improve performance characteristics, or both.4.2 Many types of recycled vulcanizate particulate rubber are available, with the number of types of vulcanizate particulate rubber limited only by the number of parent compounds.4.3 Recycled vulcanizate particulate rubber is used as feedstock for thermal decomposition, devulcanization, recovered carbon black, tire-derived aggregate, synthetic turf infill, asphalt-rubber, molded rubber products, tire-derived fuel, and other tire and non-tire derived products and end uses.4.4 Use of recycled rubber has a positive environmental impact.1.1 This classification covers the compounding material commercially known as recycled vulcanizate particulate rubber. Recycled vulcanizate particulate rubber is the product that results when vulcanizate rubber has been processed by some means to obtain a desired particle size distribution.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This 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.1.4 This 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.
