About Astm International Committee D02 On Petroleum Products, Liquid Fuels, And Lubricants
ASTM’s Automotive Lubricants Additives Proficiency Testing Program provides laboratories with a statistical quality assurance (SQA) tool, enabling them to compare, improve, and maintain, a high level of performance in the use of ASTM methods with other laboratories worldwide.
Conducted three times annually, this program provides a different commercial sample, electronic report forms, and test instructions for each test cycle. Your laboratory performs the tests that you normally conduct within your own facility using the specified ASTM methods cited in the program.
Samples, test instructions and data report forms are distributed electronically to each participant on the date samples are distributed. Labs have approximately 8 weeks to submit test data with the final statistical summary reports being electronically distributed in approximately 25 business days.
For more information, contact us.
ASTM's Proficiency Test Program provides you with:
Should you have an issue with your published results, please write to ptp@astm.org with your lab number and account number.
One-half gallon of automotive lubricant additives will be used in the program for each test cycle.
