D1238-Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer

The precision of this test method is based on an interlaboratory study of ASTM D1238, Standard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer, conducted in 2019. Eight (8)laboratories participated in this study. Each of the labs was asked to report triplicate (3) replicate test results on a total of six (6) materials. Every test result reported represents a single determination or measurement. Practice E691 was followed for the design and analysis of the data; the details are given in ASTM Research Report No. D20-2000.
