Plastics Testing (Polyethylene) Melt Index, Density, Ash, and Color
2013 Annual Fee: $439.00
Schedule: March, September
ASTM's Proficiency Test Program focuses on the determination of melt index, density, ash, and color of polyethylene materials. It provide participating laboratories with a statistical quality assurance (SQA) tool, enabling labs to compare, improve, and maintain their performance in the use of ASTM methods against other labs worldwide.
Conducted biannually, this program provides (for each test cycle) four test samples, forms to record test data, and instructions for conducting the tests. Laboratories are instructed to conduct the tests in their facilities using the ASTM methods cited in the program and to record their test results on the electronic data forms.
Each laboratory submits completed test data to ASTM for use in generating statistical summary reports. ASTM handles all data on a strictly confidential basis with no disclosure of lab identity except for one's own laboratory. Final reports contain all laboratory test data (coded), statistical analysis of test data, charts plotting test results versus lab code and other information.
The program includes lab participation worldwide, with over 95 labs participating in the 2009 program.
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.

The materials used in the program are low-density polyethylene, linear low-density polyethylene, high-density polyethylene, and high load melt index polyethylene. Each lab receives approximately one pound of polyethylene for each sample tested. The test samples are packaged and distributed for ASTM by Analytical Reference Materials International in Golden, CO.
Test samples are prepared and distributed by businesses hired for their expertise. Program registration fees include the cost of shipping the test samples.
ASTM's Proficiency Test Program provides you with:
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.
Committee D20 on Plastics, consisting of over 750 members, is a developer of 470 standards. The Committee provides the technical direction for the program. Test information from the program may be utilized by Committee D20 to determine if changes to the ASTM test methods are warranted. Data submitted to Committee D20 is coded by ASTM to maintain confidentiality.
