About The Program

ASTM International’s Transportable Moisture Limit of Coal (TMLC) Proficiency Testing Program 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 industry standard test methods with other laboratories worldwide. TML testing, measures the limit of transportable moisture for solid, bulk cargo in ocean vessels.

Conducted two times annually, this program provides a commercially available reconstituted sample, electronic report forms, and test instructions for each test cycle. Your laboratory performs the TML analyses using the available standard testing cited in the program. All data and related information generated from the program is coded to maintain lab confidentiality.

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 30 business days.

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.

Test Materials

The sample supplied will be 30 kg of reconstituted coal in accordance with IMBSC Code Appendix 2, Section 1.5, Method 2, shipped in two (2) 5 gallon plastic pails. In this process, particles above 25 mm are removed from the sample and replaced by an equivalent mass of particles in the range of 16 mm to 25 mm.

Distribution Of Samples

Test samples are prepared and distributed for ASTM International by SGS Laboratory Quality Services International (LQSi) in South Holland, IL. Program registration fees do not include the cost of shipping.

For ALL participants: You have the following options for delivery of samples to your laboratory:

  • 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.
  • Ship through a third-party shipping agent - Provide ASTM International with your shipping account number to cover shipping charges as well as 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 the shipping cost to the third-party agent and for making financial and 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.
    • 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.
