About The Program

ASTM's Proficiency Test Program on Multiplastics: Mechanical Properties Testing provides laboratories with a statistical quality assurance (SQA) tool, enabling labs to compare, improve, and maintain performance in conducting mechanical property tests on multiplastic materials.

Conducted biannually, this program provides (for each test cycle) test specimens from three different plastic materials, forms to record test data, and instructions for conducting the tests. Labs are instructed to conduct the tests in their facilities using the ASTM or ISO methods cited in the program, and to record their test results on the data report form.

Each laboratory electronically submits test data to ASTM for use in generating statistical summary reports. Final reports, contain:

  • Coded laboratory test results
  • Statistical analysis of test data
  • Charts plotting test results versus lab code
  • Other information

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 days.

For more information, contact us.

Test Materials

Plastic materials included: Reinforced Acetal, ABS, Polycarbonate, Polystyrene, Reinforced PET, and Polypropylene. Each lab receives an appropriate and sufficient number of test specimens to conduct tests according to ASTM and/or ISO methods. Each lab receives three different plastics materials in each test cycle. Extra test specimens provided.

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 with your lab number and account number.

Program Requirements

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.
