ASTM International proficiency testing program for plastic film testing

ASTM International has launched a proficiency testing program for plastic film testing (PFT) with the support by ASTM Committee D20 on Plastics.

This statistical quality assurance tool will help laboratories that want to improve and maintain a high level of performance in conducting a variety of ASTM test methods: tensile properties, propagation tear resistance (pendulum), haze, dart drop impact, tear resistance (graves tear), floss, COF and puncture-propagation tear resistance.

The program enables participants to monitor the strengths and weaknesses of their lab, to compare their test results with other labs worldwide and to help maintain accreditation status.

For each cycle, each laboratory will receive two rolls of film, each made of different materials. These rolls will be 304.8 mm wide with nominal 1 or 2 mm gauge and will contain 15 to 22 m of film to conduct the specified tests. Materials to be evaluated include LDPE, LLDPE and HDPE.

For each test trial, participants will receive two sample materials along with interactive electronic data report forms and test instructions. Labs will conduct the ASTM specified tests of their choice that they routinely run. On completion of testing, each lab will electronically submit its data to the ASTM PTP Center to generate statistical summary reports. Final reports will be electronically distributed within 25 business days of the data submission deadline, containing all test results coded to maintain customer confidentiality, statistical analysis of test data and charts plotting test results versus laboratory code.
