About Astm International Committee D02 On Petroleum Products, Liquid Fuels, And Lubricants
ASTM International's In-Service Oil Proficiency Testing Program is a statistical quality assurance tool enabling labs to compare, improve, and maintain a high level of performance in conducting tests per ASTM Intl. methods or other methods used by the lab.
Conducted three times annually, this program provides (for each test cycle) a 250 ml container of in-service diesel engine lubricating oil, data reports forms, and test instructions. A different in-service diesel engine lubricating oil will be used for each test cycle. Labs perform the tests that are normally conducted within their facility. Labs are encouraged to use the ASTM International methods, as written, however, the program will allow labs to use other methods. The other methods utilized, or any deviations from the ASTM Intl. method, must be documented with the data report form.
Test data and related information returned to ASTM Intl. will be used in generating statistical summary reports that are returned electronically to each lab. Reports contain:
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.

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 bottle containing 250ml of in-service oil and one bottle containing 20ml new oil will be used in the program for each test cycle

Test samples are prepared and distributed for ASTM International by Clark Labs in Jefferson Hills, PA. Program registration fees include the cost of shipping the test samples to U.S. participants or, for international participants, to a third-party shipping agent located in the U.S.
IMPORTANT for International participants: You have the following options for receipt of samples:
Participation is on an annual fee basis and open to all laboratories. Registration fees must be paid in advance to participate. Testing must be performed within the participant's laboratory facilities. A laboratory does not need to perform all the program tests to participate.
About ASTM International COMMITTEE D02 ON PETROLEUM PRODUCTS, LIQUID FUELS AND LUBRICANTS provides the technical direction for the program. Test information generated through the program is utilized by Committee D02 to determine if modifications to ASTM International methods or new methods are warranted and to analytically review program test results.
