Proficiency testing programs (PTPs) play an important role in maintaining the quality of data produced in a laboratory. PTPs are a useful statistical quality assurance (SQA) tools to monitor the strengths and weaknesses of a laboratory’s performance. Many laboratory accreditation agencies require laboratory participation in such programs. Two significant PTPs sponsored by American Society for Testing and Materials Committee D02 on Petroleum Products and Lubricants have been the programs on biodiesel and fuel-ethanol that were launched in the past few years. The data obtained from these SQA programs will be presented and analyzed for the lessons learned and the changes that are necessary in these PTP programs and biofuels specifications.
