This national standard specifies the product specifications for recycled plastic pellets produced through physical recycling processes such as sorting, cleaning, and melt granulation of waste polycarbonate (PC) plastics. It systematically defines the classification and naming system, various technical indicators, specific test methods, inspection rules, as well as packaging, transportation, and storage requirements for such materials. The establishment of this standard provides a unified basis for evaluating and controlling the quality of recycled polycarbonate, ensuring its effective application in high-value fields. In quality testing, to comprehensively assess the composition and performance of the material, Fourier-transform infrared spectroscopy is typically used for material identification, differential scanning calorimetry for thermal property analysis, and universal material testing machines and impact testing machines to determine key mechanical properties.
