The practice will cover the mathematical and statistical methodology involved in developing and validating multivariate (chemometric) models that relate multivariate measurements such as infrared or Raman to compositions, physical and performance properties of petroleum products, liquid fuels and lubricants. These models are employed on multivariate analyzers which are validated via ASTM D6122. The practice is will be more specific to petrochemical applications than the current E1655 practice.
Many D02 standards currently reference practice E1655 which is not within D02 jurisdiction. Changes to petrochemical application of multivariate analyzers require changes to the scope of E1655 which cannot easily be accomplished because of the lack of jurisdiction. Subcommittee D02.25 feels that D02 needs a standard more tailored to D02 applications, and has thus undertaken to develop a practice more specific to petroleum product, liquid fuels and lubricants.
