Plastics. Polypropylene (PP) and propylene-copolymer thermoplastics. Determination of isotactic index1 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 to ISO 190691[1]. This method is suitable only for base

for specific types of terminology interchange scenarios and terminological data collections can be defined

information or knowledge needs to be exchanged

Enabling better strategic planning

NOTE 1 The structure of the physical file used for exchanging the standard data defined in this part of ISO 23768 is specified in ISO 10303-21

ISO 15115 defines terms used in the leather industry
