Recycling material for copper 1 Scope This document specifies the classification, technical requirements, test methods, inspection rules, incoming inspection, transportation, storage and accompanying documents of recycling materials for copper (hereinafter referred to as "raw materials"). This document is applicable to recycling materials for copper. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB 5085.1 Identification standards for hazardous wastes - Identification for corrosivity GB 5085.2 Identification standards for hazardous wastes - Screening test for acute toxicity GB 5085.3 Identification standards for hazardous wastes - Identification for extraction toxicity GB 5085.4 Identification standards for hazardous wastes - Identification for ignitability GB 5085.5 Identification standards for hazardous wastes - Identification for reactivity GB 5085.6 Identification standards for hazardous wastes - Identification for toxic substance content GB/T 5121.1 Methods for chemical analysis of copper and copper alloys - Part 1: Determination of copper content GB/T 8170 Rules of rounding off for numerical values & expression and judgement of limiting values SN/T 0570-2022 Rules for inspection of radioactive contamination of imported recycling materials YS/T 483 Methods for analysis of copper and copper alloys - X-Ray fluorescence spectrometric (wavelength dispersive) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 copper scrap copper-containing material that is recovered after initial sorting and used to reclaim copper, which may be contaminated with or mixed with non-copper materials 3.2 recycling materials for copper copper scrap that meet the requirements for direct production and utilization after sorting, pretreatment and processing 3.3 representative sample certain quantity of physical object which is extracted from the whole batch of raw materials and can fully represent the attributes and characteristics of raw materials 3.4 foreign substance non-metallic substance mixed into raw materials during production, collection, packaging and transportation Note: It includes waste wood, waste paper, waste plastics, waste rubber, waste glass, stones and powders (such as dust, sludge, crystalline salt, metal oxide, fiber dust, etc.), but does not include packaging materials and other substances used in transportation. 3.5 radioactive contamination contamination caused by undesirable radioactive materials present on the surface of the raw material in excess of their natural amounts, resulting in technical trouble or radiation hazards [Source: GB/T 0570-2022, 3.4] 3.6 volatile substance substance that may be naturally separated from raw materials after proper heating treatment at a temperature of 350°C Note: It includes the following substances: ——Moisture, i.e. the free water adhered to the raw material and recognizable during delivery. Raw materials may bring moisture during production, collection, packaging, storage or transportation. ——Organic matter such as grease and emulsion adhered to raw materials. 3.7 non-copper metal metallic substances other than copper and copper alloys mixed into raw materials during production, collection, packaging, storage and transportation Note: In general, non-copper metal includes free iron, aluminum and aluminum alloy, zinc and zinc alloy. 3.8 physical quantity of copper ratio of copper content to the weight of the original sample after removing foreign substances, other volatile substances, non-copper metals and copper alloys per unit mass of the representative sample Note: It is expressed as mass fraction. 3.9 coating organic materials painted on the surface of raw materials Note: It generally includes logo paint, antirust paint, and insulating layer. 3.10 plating metallic material coated on the surface of raw materials Note: In general, plating includes nickel, tin, zinc, aluminum and chromium.
