Procedures A and B ISO 1133 and ASTM D1238 both offer two MFI test methods, known as Procedures A and B. Procedure A relies on a manual melt indexer making cuts at timed intervals that are then weighed on an analytical balance to determine MFI, while Procedure B features no cutting or w...
ISO 1133 and ASTM D1238 are two commonly used test methods for determining the Melt Flow Index (MFI) or Melt Flow Rate (MFR) of thermoplastic materials. Although they serve a similar purpose, there are some differences between these standards in terms of test conditions and parameters. Here a...
