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

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
