4、als ForewordThe original version of this SAE Recommended Practice was prepared jointly by the Society of Automotive Engineers and the American Society for Testing and Materials and bore the designation SAE J200/ ANSI/ASTM D 2000. This document superseded and replaced SAE J14/ASTM D 735 and was inten
5、ded to be used as a source of material quality “line call-out” specifications on procurement documents and drawings. This Recommended Practice is now under the sole jurisdiction of the SAE Committee on Automotive Rubber Specifications and bears the designation SAE J200. This document is based on bas
6、ic physical properties of rubber materials obtained directly from standard compression molded test specimens. Test specimens may be fashioned from finished products or by alternate methods. However, test specimens so prepared may be affected by forming of the product or sample and/or by shaping them
7、 for testing. Therefore, test results prepared from finished products or by alternate methods may not duplicate values obtained from standard test specimens. 1.ScopeThis classification system tabulates the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers
8、, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications. NOTE 1The SAE Committe on Automotive Rubber Specifications (CARS) has the sole responsibility for SAE J200. CARS Works closely with and receives input from ASTM Subcommittee D11.
9、30 on Classification of Rubber Compounds with the goal to keep SAE J200 and ASTM D 2000 technically equivalent. Candidate materials presented for development of new tables or for inclusion in Tables A1 or A2 of SAE J200 or Table X1.1 of ASTM D 2000 shall be initiated with the SAE CARS Committee. The
10、 procedure to be followed is detailed in Appendix C of SAE J200. NOTE 2This document may serve many of the needs of other industries in much the same manner as SAE numbered steels. It must be remembered, however, that this system is subject to revision when required by automotive needs. It is recomm
11、ended that the latest revision always be used. This document is based on the premise that all rubber materials intended for use in rubber products can be arranged into characteristic designations. These designations are determined by types, based on resistance to heat aging, and classes, based on re
12、sistance to swelling by oil. Basic levels are thus established which, together with values describing additional requirements, permit complete description of the quality of all rubber materials. In all cases where provisions of this document would conflict with those of the detailed specifications f
13、or a particular product, the latter shall take precedence. SAE J200 Revised DEC2001 -2- NOTE 3When the rubber product is to be used for purposes where the requirements are too specific to be completely prescribed by this classification system, it is necessary for the purchaser to consult the supplie
14、r in advance to establish the appropriate properties, test methods, and specification test limits. 1.1Purpose 1.1.1The purpose of this document is to provide guidance to the engineer in the selection of practical, commercially available rubber materials, and further to provide a method for specifyin
15、g these materials by the use of a simple line call-out designation. 1.1.2This document was developed to permit the addition of descriptive values for future rubber materials without complete reorganization of the classification system and to facilitate the incorporation of future new methods of test
16、 to keep pace with changing industry requirements. 2.References 2.1Applicable PublicationsThe following publications form a part of this specification to the extent specified herein. 2.1.1ASTM PUBLICATIONSAvailable from ASTM, 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959.
