Описание (английский):

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.

Abstract

Overview

ISO 9113:2019 specifies a chemical-extraction method to determine the isotactic index of crystalline polypropylene (PP) and propylene‑copolymer thermoplastics. The standard measures the n‑heptane extractable matter from a solid propylene polymer sample under defined conditions, and reports isotactic index as an absolute value (II = 100 − S). It is applicable to base polymers (not mixtures) and supports identification/coding of types H, B and R in accordance with ISO 19069‑1.

Key topics and requirements

Scope and limitation
- Applies only to solid propylene plastics in particle form and to base polymers (not blends).
- Provides results used to classify types H, B and R (see ISO 19069‑1).
Sample preparation
- Reduce material to particles that pass a sieve (recommended mesh 0.5 mm ± 0.1 mm; not greater than 1 mm).
- For grinding: mix at least 10 g sample with solid CO2 or liquid nitrogen and mill; allow screened material to equilibrate to room temperature.
Apparatus & consumables
- Extraction apparatus suitable for boiling n‑heptane and cartridges (glass fibre or paper, Ø 30 mm ± 3 mm, length 100 mm ± 10 mm).
- Ovens capable of 70 °C ± 2 °C and 140 °C ± 2 °C with vacuum
