Secondarily lead and lead alloy ingots1 ScopeThis Standard specifies the requirements, test methods, inspection rules and marks, packaging, storage, transport, quality certificate and purchase order (or contract) of secondarily lead and lead alloy ingots. This Standard is applicable to secondarily lead and lead alloy ingots that take lead-containing waste as raw material and are through smelting processing production, mainly used for storage batteries, alloys and chemical industry and other fields.2 Normative referencesThe following referenced documents are indispensable for the application 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.

ZSPb99.994, ZSPb99.992, ZSPbSb1, ZSPbSb2, ZSPbCa, ZSPbSn1, ZSPbSn2. 3.2 Chemical composition 3.2.1 The chemical composition of secondarily lead and lead alloy ingots shall comply with the provisions of Table 1. 3.2.2 When the purchaser has special requirements for alloying elements5 Inspection rules5.1 Inspection and acceptance 5.1.1 The secondarily lead and lead alloy ingots shall be inspected by supplier’s technical supervision department so as to ensure that the product quality complies with the provisions of this Standard or purchase order (or contract) and fill in the quality certificate. 5.1.2 The purchaser shall inspect the product received according to the provisions of this Standard. If the inspection results fail to comply with the provisions of this Standard or purchase order (or contract), the purchaser shall put forward to the supplier within 15 days after the product is received. It shall be solved by the supplier and the purchaser via negotiation. If arbitration is required, the sampling for arbitration shall be carried out by the supplier and the purchaser. 5.2 Batching 5.2.1 The secondarily lead and lead alloy ingots shall be submitted in batches for inspection. Each batch shall consist of the products of same smelt number. The batch shall not exceed 120 t. 5.2.2 According to purchaser’s needs, allowing a number of batches of the same designation to form an inspection batch. The batch size shall be carried out according to purchaser’s requirements. 5.3 Inspection items Each batch of secondarily lead and lead alloy ingots shall be subjected to the inspections of chemical composition and surface quality. 5.4 Arbitration sampling and sample preparation 5.4.1 Arbitration sample quantity. extract 2% of secondarily lead and lead alloy ingots at random as sample ingot. The total number of sample ingot shall be multiple of 6 for easy grouping. When there is less than 6 after grouping, it shall make up from the secondarily lead and lead alloy ingots but it must not discard. 5.4.2 Arbitration sampling method. make each 6 extracted sample ingots as a group. Take a sample by drilling or sawing. During drilling or sawing, it must not use any lubricant. Its speed must not oxidize the sample. Sampling shall remove the skin. The drilling, sawing depth must not be less than 2/3 of ingot thickness. Details are as follows. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al. |
