The foreign designations corresponding to the famous designations are shown in Annex C. inclusions, cold insulation, pores, porosity, shrinkage holes, and lack of meat that affect performance. 4.4.3 The surface roughness of castings is selected according to GB/T 6060.1. It is specified in the drawing or order contract. 4.5 Dimensional, geometric and weight tolerances The geometrical shape, dimensional tolerance, geometrical tolerance and weight tolerance of castings shall conform to the stipulations in the drawing or order contract. If there is no corresponding stipulation in the drawing and order contract, the dimensional tolerance of castings shall be selected according to GB/T 6414; the weight tolerance of castings shall be selected according to GB/T 11351. 4.6 Weld repairs 4.6.1 Casting defects allow weld repair. Defects shall be cleaned before welding. The edges of the cleaned area shall be overly rounded. When necessary, magnetic particle or penetrant testing is required before and after welding repairs. Weld repairs shall not affect the use and appearance quality of the castings. 4.6.2 When the groove depth prepared for welding repair exceeds 40% of the wall thickness of the welding repair part or 25mm (whichever is the smaller groove depth), it is a major welding repair. Special circumstances are negotiated by both parties. 4.6.3 Major welding repairs shall be approved by the purchaser. For major welding repairs, the location and scope of welding repairs shall be recorded. Welding conditions are determined by both the supplier and the purchaser. If the purchaser has requirements for pre-welding preparation, electrode material, welding repair process, post-weld treatment and post-weld inspection, it shall negotiate with the supplier to decide. 4.6.4 After the casting is repaired by welding, it shall be treated with stress relief. Special circumstances are negotiated by both parties.5 Test methods5.1 Chemical composition analysis 5.1.1 The preparation method of the sample for chemical composition analysis shall be carried out according to the provisions of GB/T 20066. 5.1.2 The analysis method of chemical composition can be according to GB/T 223.4, GB/T 223.5, GB/T 223.11, GB/T 223.14, GB/T 223.20, GB/T 223.21, GB/T 223.22, GB/T 223.23, GB/T 223.26, GB/T 223.43, GB/T 223.54, GB/T 223.59, GB/T 223.63, GB/T 223.64, GB/T 223.67, GB/T 223.69. 5.1.3 Spectral multi-element analysis is carried out in accordance with the provisions of GB/T 4336, GB/T 11170 and GB/T 14203. 5.2 Hardness test Brinell hardness test is carried out according to the provisions of GB/T 231.1. In special cases, it can also be tested with a portable hardness tester and converted into a Brinell hardness (HBW) control. 5.3 Nondestructive testing 5.3.1 Magnetic particle testing is carried out in accordance with the provisions of GB/T 9444. 5.3.2 Penetration testing is carried out in accordance with the provisions of GB/T 9443. 5.3.3 Ultrasonic testing is carried out in accordance with the provisions of GB/T 7233.1. 5.3.4 Radiographic testing is performed in accordance with the provisions of GB/T 5677. 5.4 Surface roughness The surface roughness shall be carried out according to the provisions of GB/T 6060.1 and GB/T 15056. 5.5 Geometry and dimensions The inspection of casting geometry and dimensions shall be carried out by selecting inspection tools with corresponding precision and combining with the method of scribing.6 Inspection rules6.1 Batching Divide inspection batches in one of the following ways: a) Batch by heat: Castings of the same designation, cast in the same heat and heat- treated in the same heat constitute an inspection batch; b) Batch by quantity or weight: Under the condition of stable smelting or manufacturing process, a certain number or a certain weight of castings of the same designation that are cast in multiple heats or the same casting process and subjected to the same heat treatment process for multiple heats constitute an inspection batch; c) Batch by piece: For some special casting process requirements, one or several pieces constitute an inspection batch. 6.2 Chemical composition test 6.2.1 The chemical composition inspection is carried out according to the heat (piece, batch). Specimens for chemical composition analysis are taken from attached or single cast test blocks. If the thickness of the test block or casting is less than 15mm, the analysis sample shall be taken from the middle part of the wall thickness of the test block or casting. If the thickness of the test block or casting is greater than or equal to 15mm, the sample for analysis shall be taken at least 6mm below the surface of the test block or casting. 6.2.2 When pouring a casting in multiple packs, each pack shall be sampled for analysis. The analysis results of each package shall conform to the chemical composition of the designations selected in Table 1. 6.3 Hardness test 6.3.1 The hardness shall be tested at a point greater than or equal to 2 mm below the surface of the test block or casting. When it is difficult to test on the body of the casting, the hardness can also be tested on the attached casting block of the casting. 6.3.2 Hardness testing is done in batches. Randomly select 3 castings (or 3 test blocks) from each batch for inspection. If one piece fails, the same number of castings (test blocks) can be randomly selected for re-inspection. When the number of rejected castings (test blocks) sampled twice is greater than or equal to 2, the batch of castings is rejected. If there are 2 pieces (test blocks) rejected in the first sampling, the batch of castings is rejected. 6.3.3 When the hardness test fails, the batch of castings and test blocks are allowed to be reheated. And then the hardness is retested. If the hardness test is accepted after re- heat treatment, the batch of castings is still accepted. However, without the consent of the purchaser, the reheat treatment of castings and test blocks shall not be more than two times. 6.4 Nondestructive testing The non-destructive testing methods, testing locations, testing quantities and acceptance criteria for castings shall be agreed upon by both parties.7 Marks, packaging and storage7.1 Marks and certificates of conformity 7.1.1 Each (batch) casting surface (or package surface) shall at least have the following identifications: a) Purchaser's name and address; b) Casting name, specification and material designation; c) Packing number; d) Gross weight and net weight; e) Supplier name and address; f) When marking cannot be made on the casting, the marking can be printed on the label of each (batch) casting. 7.1.2 The exit-factory castings shall be accompanied by a certificate of conformity with a seal issued by the quality inspection department, which shall at least include the following contents: a) Supplier name and address; b) Trademark; c) Casting name and material designation; d) Casting inspection lot number; e) Inspection results (inspection report), the code of the inspector; f) Casting drawing number or order contract number; g) Reference to standard; h) Exit-factory date. 7.2 Packaging and storage 7.2.1 Castings shall be protected, rust-proof and properly packaged after inspection. Castings shall be stored in a dry, rain-proof, level and solid site. 7.2.2 Castings shall be protected from corrosive substances such as acid and alkali during storage and transportation. 7.2.3 Casting protection, packaging, storage and transportation shall comply with the provisions of the order contract. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
