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
ASTM's Engine Coolants Proficiency Test Program provides laboratories with a statistical quality assurance (SQA) tool, enabling labs to compare, improve, and maintain performance in the use of ASTM methods against other laboratories worldwide
As a program participant, you receive different samples (representative of the product line) for each test cycle, electronic report forms and test instructions. Your laboratory performs the tests that you normally conduct within your own facility using the specified ASTM methods cited in the program.
For more information, contact us.
You receive test results available only to participating laboratories that will help you:
Should you have an issue with your published results, please write to ptp@astm.org with your lab number and account number.
One gallon of engine coolant material will be used in the program for each test cycle.

Test samples are prepared and distributed for ASTM International by SGS North America, Deer Park, TX. Program registration fees include the cost of shipping test samples to U.S. participants or, for international participants, to a third party shipping agent located in the U.S.
IMPORTANT for Intercontinental participants: You have the following options for receipt of samples:
Upon completion of tests, each laboratory electronically submits their test data to ASTM for use in generating statistical summary reports. Reports contain:
Committee D15 on Engine Coolants, consists of over 130 members and developers of over 39 ASTM standards, provides the technical direction for the program. Test information generated through the program is utilized by Committee D15 to determine if modifications to ASTM documents or new methods are warranted. Data submitted to Committee D15 is coded to maintain lab confidentiality.
