Rationale: During the 5-year review, “test fixture adaptor plate” was made consistent in Figure 1 where the terms “test fixture adaptor plate” and “adaptor plate” were previously used. “slr” and “d” dimensions were referenced as “m(in)” where “mmx10-3 (in) was previously used. Table 3 data in “mm” was converted to “m” units. Table 1 added mounting system column and corrected hole pattern diameters, 8.000 corrected to 8.071 inch, Added row for 13.188 inch bolt circle. Removed 170mm bolt circle. Hub bolt circles are listed in units native to each mounting system. 17.15 was 17.16. Bottom note for plate stress was removed. Reference to SAE J694 dimensions was added. Equation 1 font now italics. 3.2.3 “Equation 1” removed from equation description. Table 2, note 2 was clarified to show dry torque meaning no additional lubricants from a fastener in new condition. Added section 2.1.2 for tire and rim association reference. Section 3.2.3, 3.3.3, and 3.3.4: S is defined as the “accelerated load factor” and was “test factor”. Note of table 1 was removed as being obsolete and unnecessary. Table 3 note for tire sizes not shown was reworded to match J267. Added “http://www.us-tra-org to bottom note. Table 4 was moved to section 3.3.4 and was in section 3.5. Cells of table 4 are merged and centered.
