ASTM’s Octane Rating and Proficiency Testing Program for Motor Gasoline 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. Octane engine testing, also known as "engine knock test", measures gasoline characteristics related to engine knocking using ASTM International Standards. Octane testing labs will measure gasoline samples from refineries, storage facilities, storage tanks and pipelines for octane ratings and many other gasoline fuel quality properties. As an added benefit, this program will use the same fuel as used in our Motor Gasoline Proficiency Testing Program, which contains a host of other ASTM test parameters since not all labs have the proper engine knock testing equipment; http://www.astm.org/STATQA/Motor_Gas.htm.
Conducted three times annually, this program provides a different commercial sample, electronic report forms, and test instructions for each test cycle. The Octane Expansion Program is an add-on program to Octane Testing and is available to provide additional test cycles to enhance your laboratory’s quality program. This add-on program is also offered three times annually, 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.

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 is 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.
