1 Subject Content and Application Scope This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation and storage, etc. of non-ferrous alloy in engineering machinery products. This standard is applicable to sand, metallic or investment copper-based, aluminum-based or zinc-based alloy castings. 2 Normative References GB 8063 Designation of Cast Nonferrous Metals and Their Alloys GB 1198 Methods for Chemical Analysis of Aluminum GB 6987 Methods for Chemical Analysis of Aluminum Bronze GB 1173 Casting Aluminum Alloys GB 8002 Methods for Chemical Analysis of Tin Bronze GB 5122.1~5122.20 Methods for Chemical Analysis of Brass GB 228 Tensile Test Method for Metal GB 231 Metallic Materials - Brinell Hardness Test GB 2828 Sampling Procedures and Tables for Lot-by-lot Inspection by Attributes (Apply to Inspection of Successive Lots or Batches) 3 Technical Requirements 3.1 Casting Classification 3.1.1 Castings are classified into three types according to working conditions, purposes and hazard degrees caused by damage, and shall be indicated in figures and relevant technical documents. The unindicated casting type is considered as Type 3. Type 1 casting: key casting bearing working conditions such as large dynamic load, static load and alternate load or that endangering the safe operation of main machine where damaged. Type 2 casting: important casting bearing medium static load and dynamic load or that endangering the normal operation of component where damaged. Type 3 casting: general-purpose light-load casting. 3.1.2 Example of casting label Figure label of casting covers alloy designation or code, casting method, supply state, casting type and code of this standard. Example of label:
