About The Program

ASTM’s Proficiency Test Program provides laboratories with a testing program that enables labs to compare, improve and demonstrate their proficiency in performing a commonly used small scale laboratory flammability test on centrally prepared plastic test specimens.

Conducted twice a year, this program provides prepared test specimens fabricated from two different engineering resins for each test cycle, data recording forms and protocols for conducting each test. The test specimens will be centrally prepared in accord with specific ASTM requirements and distributed to all program participants by Lansen Mold Co., Lanesboro, MA.

Each laboratory electronically submits their completed test results to ASTM for use in generating statistical summary reports. Electronic 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.

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.
  • A stable and homogeneous test material that may be used for quality control

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

Test Materials

Each lab will receive sufficient quantities of test specimens to conduct the program test each test cycle. Extra specimens are supplied for testing purposes as needed. Program registration fees include test specimen shipping costs to all registered participants.

Distribution Of Samples

Test samples are prepared and distributed by businesses hired for their expertise. Program registration fees include the cost of shipping the test samples.

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.
