<p>This document specifies a relative method for the determination of polypropylene (PP) isotactic index by low-resolution pulsed nuclear magnetic resonance spectroscopy (LR-NMR).</p>
<p>This method enables the identification and coding of types H propylene (PP-H) plastics according to ISO 19069‑1.</p>
<p>This method is suitable for base polymers and is not applicable for mixtures.</p>
<p>NOTE The direct method for the determination of polypropylene isotactic index is specified in ISO 9113.</p>
