This standard specifies product specifications for recycled plastic pellets manufactured from waste polypropylene plastics through processes such as screening, cleaning, and melt granulation. It systematically outlines the classification and naming, technical requirements, test methods, inspection rules, packaging, and storage for such recycled materials, providing a unified technical basis for quality control and trade circulation of related products within the industry. To accurately evaluate the various properties of recycled polypropylene, the standard references a variety of general plastic testing methods. Among these methods, equipment such as Fourier-transform infrared spectrometers, differential scanning calorimeters, and thermogravimetric analyzers may be used for material composition and performance analysis.
