2019 Annual Fee (Including Sample Preparation):
ASTM's Proficiency Test Program provides laboratories with a testing program that enables labs to compare, improve, and maintain performance in preparing polypropylene test samples and in conducting mechanical property tests on them.
Conducted biannually, this program provides (for each test cycle) two different polypropylene resins, electronic report forms, and instructions for conducting the tests. Labs are instructed to prepare their samples in accord with specific ASTM and ISO standards. Labs then conduct tests in their facilities using the prepared specimens and the ASTM and ISO methods cited in ASTM D 4101 and ASTM D 5857, and record their test results on the data report forms. Each laboratory returns completed data report forms to ASTM for use in generating statistical summary reports. Published reports contain:
Participants are required to utilize molds and molding equipment capable of producing injection molded specimens per ASTM D 4101 and/or ASTM D 5857. Companies with multiple molding machines or laboratories may elect to use one or all of their facilities however, each unit's data will be treated as an individual participant and as an annual subscriber to the testing program.
Samples, test instructions, and electronic report forms are distributed during the last week preceding the testing month. Labs have approximately one month to return test data to ASTM with final summary reports sent to participants approximately one month following receipt of test data.

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 firstname.lastname@example.org with your lab number and account number.
Test samples are prepared and distributed for ASTM International by Clark Labs in Jefferson Hills, PA.
IMPORTANT for International participants: You have the following options for receipt of samples:
Committee D20 on Plastics has 750 members and is a developer of 470 standards. The Committee provides the technical direction for the program. Test information generated through the program is utilized by Committee D20 to determine if modifications to the ASTM test methods are warranted.
Committee D20 is coded by ASTM to maintain confidentiality.
