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 Petroleum Wax Proficiency Testing Program provides laboratories with a statistical quality assurance tool, enabling them to compare, improve, and maintain, a high level of performance in the use of ASTM physical property tests on petroleum waxes with other laboratories worldwide.
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 email@example.com with your lab number and account number.
Three types of petroleum waxes will be used in program testing, namely; fully refined paraffin waxes, slack or scale waxes and high molecular weight waxes. A 2.7 kg (approx 6 lb) sample of "one program wax" will be provided to each participant each test cycle.
Samples, test instructions, and data report sheets are distributed to each participant preceding the testing month. Labs have approximately six weeks to return test data to ASTM with final summary reports mailed to participants approximately 20-25 business days following receipt of test data

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.
