Scope
Main technical content: This standard specifies two methods for measuring the melt mass flow rate (MFR) and melt volume flow rate (MVR) of thermoplastic elastomers. Method A is the mass method, and Method B is the volume method. This standard is applicable to olefin-based thermoplastic elastomers (POE), styrene-based thermoplastic elastomers (TPE-S), thermoplastic elastomers (TPU), and dynamic vulcanized thermoplastic elastomers (TPV).
