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.
