    Rationale

    Existing volumetric reference fuel blending requirements have criteria intended for manual blending apparatus. Automated volumetric blending apparatus may have different physical properties yet still be capable of complying with blending tolerance requirements of the test method. This revision adds a clause stating appropriate requirements for automated volumetric blending of reference fuels.
