Thanks for your question. I spoke with a collegue at ASTM D20 who works with polyethlene. He told me that it is a common test in the industry (and PP as well) but there are a number of different molds and procedures. There is no standardized procedure in ASTM for the test. I\'m not sure about ISO. I\'ll check on that and if I find something, I\'ll let you know. Thanks again. HEY
