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 International Proficiency Testing Center is pleased to offer a Proficiency Testing Program on Aromatic Hydrocarbons to laboratories who need a statistical quality assurance tool that will enable them to improve, and maintain a high level of performance in conducting routine ASTM aromatic hydrocarbon tests by comparing their results with other laboratories worldwide doing the same testing.
As a program participant, you will receive a mixed xylene, p-xylene and benzene sample and all the necessary instructions necessary for the test trial. Your laboratory performs the tests that you normally conduct within your own facility using the specified ASTM methods cited for each program sample. Labs have eight weeks to electronically submit their data to ASTM. Final summary reports are electronically delivered to all participants in 20-25 business days after the test cycle. The statistical summary report for the test will be electronically delivered to each participant. The reports will contain:

These programs are designed to provide participating laboratories with a statistical quality assurance tool enabling them to assess their performance in how they conduct a given test or series of tests by comparing their data against the data of other participating laboratories.
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.
Each participating lab will receive 2 – 500 mL bottles of mixed xylene and a 500 mL bottle of p-xylene and a 250 mL bottle of benzene for each of the two test trials conducted each year in FEBRUARY AND SEPTEBMBER.

Test samples are prepared and distributed for ASTM International by AccuStandard of New Haven, CT. 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: 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 advanced 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.
Committee D16 on Aromatic Hydrocarbons has 126 members and 83 published ASTM standards. This committee provides the technical direction for the PTP program. Test information generated through the program is utilized by Committee D016 to improve standard tests. Data are coded at all times.
Committee D16 reviews test results and improves test methods based on PTP results.
