GB/T 46442-2025 is suitable for recycled plastic particles and sheet samples made of waste plastic recycling from thermal plasticity, and clarifies the detection principle, instrument requirements, operation process and data processing methods. The test needs to be based on CIE standards, using Colorimeter (including Handheld, Benchtop, etc.), quantifying Color differences under specified Illuminant and detector conditions, providing a unified technical basis for mass control and trade inspection of recycled plastics, and helping the development of industry standardization.
