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 not limited to, use in rubber products for automotive applications.

NOTE 1: The SAE Committe on Automotive Rubber Specifications (CARS) has the sole responsibility for SAE J200. CARS Works closely with and receives input from ASTM Subcommittee D11.30 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 procedure to be followed is detailed in Appendix C 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. 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 resistance 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 for a particular product, the latter shall take precedence.

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 specification test limits.

Rationale:

Editorial Changes: BK basic requirements table inadvertently 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 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 in 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 Method 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 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.
