Scope

This standard specifies the methods for determining the melting behavior of partially crystalline polymers using capillary method and polarizing microscope method. Method A (capillary method) is suitable for all partially crystalline polymers and their blends. Method B (polarizing microscope method) is suitable for polymers with birefringent crystalline phases. However, it is not suitable for blends containing pigments and/or additives, as they may affect the birefringence of the polymer's crystalline regions.
