this document is intended as an educational guide that outlines the types of changes to synthetic turbine oils managed by the AS5780 Qualified Product Group (QPG). The document describes and provides examples for the Management of Change classifications listed in AS5780 Section 10 and as appropriate links these to the allowable Manufacturing Tolerances listed in AS5780 Section 7. The document also describes the oil certification differences between Major and Minor changes being evaluated by the AS5780 QPG.
This document is intended to summarize the good debate the committee has had since 2012 on the subject on the delineation of Major and Minor changes. The document is intended as a reference to future SAE E34 members who either may be submitting changes to or participating in the AS5780 QPG process.
