Plastics — Polypropylene (PP) and propylene-copolymer thermoplastics — Determination of isotactic index

Plastiques — Thermoplastiques à base de polypropylène (PP) et de copolymères de propylène — Détermination de l'indice d'isotacticité

This edition has been replaced by ISO 9113:2019.

Abstract / scope

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. A powdered test portion is carefully dried, weighed and extracted in as Soxhlet-apparatus with n-heptane during 24 h. The mass of residue of the test portion is determined and according to ISO 1873-1 reported as isotactic.
