DESCRIPTION

BS ISO 9113:2019

This standard BS ISO 9113:2019 Plastics. Polypropylene (PP) and propylene-copolymer thermoplastics. Determination of isotactic index is classified in these ICS categories:

83.080.20 Thermoplastic materials

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 to ISO 19069-1^[ ¹^].

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.
