Approved by Designation: D 2000 – 03a Society of Automotive Engineers SAE mended Practice J200 Standard Classification System for Rubber Products in Automotive Applications1 This standard is issued under the fixed designation D 2000; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. This specification has been approved for use by agencies of the Department of Defense. 1. Scope D 395 Test Methods for Rubber pression This classification system tabulates the properties of Set vulcanized rubber materials (natural rubber, reclaimed rubber, D 412 Test Methods for Vulcanized Rubber and Thermo- synthetic rubbers, alone or bination) that are intended plastic Rubbers and Thermoplastic Elastomers—Tension for, but not limited to, use in rubber products for automotive D 429 Test Methods for Rubber Property—Adhesion to applications. Rigid Substrates D 430 Test Methods for Rubber Deterioration—Dynamic NOTE 1—This classification system may serve many of the needs of Fatigue other industries in much the same manner as SAE numbered steels. It must D 471 Test Method for Rubber Property—Effect of Liquids be remembered, however, that this system is subject to revision when required by automotive needs. It is mended that the latest revision D 573 Test Method for Rubber—Deterioration in an Air always be used. Oven D 575 Test Methods for Rubber Properties pression This classification system is based on the premise that D 624 Test Method for Tear Strength of Conventional the properties of all rubber products can be arranged into Vulcanized Rubber and Thermoplastic Elastomers characteristic material designations. These designations are D 865 Test Method for Rubber—Deterioration by Heating determine
