Scope: This document specifies a method for determining the percentage of matter which can be extracted from crystalline propylene plastics by boiling n-heptane under standard conditions of testing. Isotactic index is determined by conventional chemical extraction as an absolute method. This method provides for the identification and coding of types H, B and R propylene plastics according This method is suitable only for base polymers and is not applicable for mixtures. This method starts with solid propylene plastics in the form of particles of specified fineness.
