About The Program

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.

Why Should Your Laboratory Participate?

ASTM's Proficiency Test Program provides you with:

  • A useful and meaningful statistical quality assurance tool to monitor the strengths and weaknesses of your laboratory's performance in conducting testing.
  • The resource you need to satisfy proficiency testing elements of laboratory accreditation.
  • A periodic comparison of test results with other participating laboratories.

Should you have an issue with your published results, please write to ptp@astm.org with your lab number and account number.

Test Materials

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 2.04 kg (approx 4.5 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

Distribution Of Samples

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:

  • Ship through a third party shipping agent - Provide ASTM International with the complete contact information of a designated Shipping Agent located in the U.S. who will be responsible for shipping samples from the U.S. to your facility. Participants are responsible for making financial and shipping arrangements directly with the shipping agent.
    • Please be advised that when samples are shipped, an e-mail is sent only to the contact of record on your ASTM PTP account. It is the customer’s responsibility to advise their designated shipper that the sample has been shipped.
    • We cannot permit shipping agents to pick up samples at our distributors’ warehouses.
  • Ship directly from the sample distributor via UPS, DHL, or FEDEX - Provide ASTM International with your shipping account number to cover shipping charges. Check that your carrier will deliver the test materials to your location. Materials classified as Hazardous may have restrictions.
    • You are responsible for additional fees charged-back to our distributor for any reason relative to your sample shipment including, but not limited to, fees for fuel surcharges, missing/invalid account numbers, dangerous goods, remote area delivery, and multiple delivery attempts.
