Classification System for Rubber Materials
- Ground Vehicle Standard
- J200_200805
- Revised
Scope
Rationale
-
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.

Issuing Committee
Committee on Automotive Rubber Specs
The Committee on Automotive Rubber Specifications (C.A.R.S.) develops and maintains SAE Standards, Recommended Practices and Information Reports relating to the development of thermoset and thermoplastic elastomer specifications for use in automotive and related industries. The J200 HK Table Task Force is updating the classification and characterization of fluorocarbon elastomers (FKM), which will make the table more useful to users of this family of elastomers. The Engine Oil Comp. with Rubber Gaskets and Seals is working on standard reference elastomers to be used in evaluation of current and future engine oils. These standards can be used for comparative studies, to determine the possible deleterious effects of oil technology changes on elastomers used in automotive and related applications. Participants in the SAE Committee on Automotive Rubber Specifications include OEMs, suppliers, consulting firms, government and other interested parties.
