Scope

Main Technical Content: This standard comprehensively stipulates the technical requirements and certification norms for the recycling and reuse of marine plastics, applicable to plastic waste recovered in China's jurisdictional waters (including inland waters, territorial seas, exclusive economic zones, etc.) and high seas areas. In terms of plastic types, the standard applies to major plastic varieties such as PET (recycling rate ≥92%), HDPE (recycling rate ≥90%), and PP (recycling rate ≥88%), requiring that the recycled plastics undergo professional testing to confirm their marine exposure characteristics (salt content ≥0.5%, bio-adhesion rate ≥30%, and UV aging index ≥2). For difficult-to-recycle plastics such as PVC, this standard can be referenced, but additional environmental protection requirements must be met. In terms of technical processes, the standard regulates key process steps such as marine plastic recycling classification (manual sorting accuracy ≥95%, mechanical sorting efficiency ≥2t/h), deep cleaning (≥3 stages of cleaning process, salt removal rate ≥99.5%), regranulation (melt flow index change ≤15%, tensile strength retention rate ≥85%), and modification applications (additive proportion ≤5%). The system must support full-chain traceability from source to product (data integrity rate ≥99.9%) and establish a graded certification system (Class A: marine plastic content ≥95%; Class B: 70-95%; Class C: 30-70%). In terms of performance indicators, recycled marine plastics should meet quality requirements such as basic physical properties (melt flow rate change ≤15%), mechanical properties (tensile strength ≥85% of raw materials), hygiene and safety (total heavy metal content ≤100mg/kg), and processing performance (molding shrinkage rate change ≤20%). The certification system must ensure 100% authenticity of testing data, a certification pass rate ≥95%, and 100% compliance with labeling standards. For special-use materials such as food contact, they m
