This program is accredited in accordance with the recognized International Standard ISO/IEC 17043: 2010 Conformity Assessment - General Requirements for Proficiency Testing, by the American Association for Laboratory Accreditation. Certificate Number: 4209.01
The Ultra-Low Sulfur Diesel (ULSD) Proficiency Testing Program will provide laboratories with a statistical quality assurance tool, enabling them to compare, improve, and maintain, a high level of performance in the use of ASTM sulfur measurement tests on commercial ultra-low sulfur diesel fuels containing 15ppm or less with other laboratories worldwide. US-EPA and CARB labs will be invited to participate.
The objectives of the program are twofold, namely; 1) to gain experience in measuring the sulfur concentration at the ultra-low levels present in ULSD, and 2) to compare your performance with other participating labs using specific ASTM tests for the determination of sulfur.
As a program participant you will receive a 110mL sample of an ULSD monthly along with a notice on how to access the trials electronic report forms and test instructions. Your laboratory will perform the tests that you normally conduct within your own facility using the specified ASTM program tests and/or your performance based measurement methods (as approved by the EPA).
Samples, test instructions and data report forms are distributed electronically to each participant on the date samples are distributed. Labs have approximately 4 weeks to submit test data with the final statistical summary reports being electronically distributed in approximately 15 business days.

Should you have an issue with your published results, please write to firstname.lastname@example.org with your lab number and account number.
Twelve (12) samples of Ultra-Low Sulfur Diesel containing not more than 15 ppm sulfur will be distributed during the course of the year. A 110mL of test material will be provided to each participant for each test cycle each month.

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.
