5、rtently lists Tensile change of 30% twice. Redundancy was removed. J3000 is no longer an active document, and the reference to it in the Appendix C title was removed. Balloted Changes: 1. Table 4, footnote 10 use to be part of footnote 8, but was inadvertently labeled as a separate footnote during a
6、 recent table revision. Footnote 11 actually refers to items footnoted as 10. Moved footnote 10 text to footnote 8. Relabeled footnote 11 as footnote 10. Relabeled footnote for K3 adhesion to refer to footnote 10. 2. Table 4, removed reference to paragraph 7.5 of D1329. No paragraph 7.5 is present i
7、n D1329. 1977 ASTM version shows 7.5 is now 8.5, but is redundant as it is part of the basic procedure of D1329, Same rationale for removal of 10 minute holding time. Changed sample size to 38 from 38.1 to be consistent with D1329. 3. Table 4, Added F7 for TR-70. 4. Deleted Method A from C1 and Meth
8、od B from C3 in Table 4. Revised footnote references for these, incorporating the consolidation of D 1171 ozone chamber testing into D1149. D1171 Outdoor aging is not affected. 5. Revised reference section. Added D1149 for chamber deterioration evaluations. 6. Revised text in Table 3 and all suffix
9、tables (Table 6) regarding use of “Z”s in call out. Clarification of use for rubber characteristics only. 7. Added “Z” as an available suffix for Table 6, EE and EK. Author:Gilligan-SID:9234-GUID:24306123-155.69.4.4 SAE J200 Revised MAY2008 - 2 - FOREWORD The original version of this SAE Recommended
10、 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 This document superseded and replaced SAE J14/ASTM D 735 and was intended to be used as a source of material quality “line call
11、- 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 basic physical properties of rubber materials obtained dire
12、ctly 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 for testing. Therefore, test results prepared from fini
13、shed products or by alternate methods may not duplicate values obtained from standard test specimens. 1. SCOPE This classification system tabulates the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for, but
14、not limited to, use in rubber products for automotive applications. NOTE 1: The SAE Committee on Automotive Rubber Specifications (CARS) has the sole responsibility for SAE J200. CARS Works closely with and receives input from ASTM Subcommittee D11.30 on Classification of Rubber Compounds with the g
15、oal 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 procedure to be followed is detailed in Appendix C
16、 of SAE J200. NOTE 2: This 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 recommended that the latest revision always be used. Th
17、is 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 resistance to swelling by oil. Basic levels are thu
18、s 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 for a particular product, the latter shall take pr
19、ecedence. NOTE 3: When 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 supplier in advance to establish the appropriate properties, test methods, and spec
20、ification test limits. 1.1 Purpose 1.1.1 The 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 specifying these materials by the use of a simple line call-out designation. 1.1.2
21、This 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 to keep pace with changing industry requirements.
