Rationale: This procedure has been revised to harmonize terminology across related SAE documents with the latest regulatory test procedure references. Clarifications were made to calculation definitions, computations, and evaluation of results as well as clarifying the text where definitions are referenced. Equations were reorganized to maintain consistency across the document. A spreadsheet based tool was developed that can be used to provide an evaluation reference for the calculation procedure, or to provide a step-by-step calculation verification for existing software.
