Rationale

Revision to remove the parenthetical SI unit conversions from Annex A2- Permitted Variations in Dimensions—Inch-Pound Units. The conversions within Annex A3 are for information only. When specifying to A480M, the SI unit values in Annex A3 must be used. The purpose of this revision is to eliminate potential confusion between the SI conversions in Annex A2 and the standard SI unit requirements in Annex A3.
