According to the official information released by the National Standards Committee, the national standards officially implemented since April 25 have been compiled, including six national standards centrally managed by the National Casting Standardization Technical Committee (SAC/TC 54), see the following table for details.
| standard number | standard name | standard content |
| GB/T 8924-2024 | "Heat-resistant Steel and Alloy Castings for General Purpose" | This document specifies the manufacture, technical requirements, test methods, inspection rules and marking, quality certificates, packaging, storage and transportation of heat-resistant steel and alloy castings for general use. This document applies to general purpose heat-resistant steel and alloy castings used under high temperature conditions. Other types of heat-resistant steel and alloy castings can also be referenced. |
| GB/T 9442—2024 | "Foundry sand" | This document specifies the classification and grade of foundry sand, technical requirements, test methods, inspection rules and packaging, marking, transportation and storage. This document applies to silica sand used in casting production for molding and core making, including natural silica sand and artificial silica sand such as washing sand, scrubbing sand, selected sand and calcined sand. |
| GB/T 13818—2024 | "Die casting Zinc Alloy" | This document specifies the grades and codes of die casting zinc alloys, technical requirements, test methods, inspection rules and marks, quality certificates, packaging, transportation and storage. This document is applicable to the production and inspection of die-cast zinc alloys. |
| GB/T 14408—2024 | "Low alloy steel castings for general engineering and structural applications" | This document specifies the manufacturing, technical requirements, test methods, inspection rules, marking and quality certificates of low alloy steel castings for general engineering and structural use, and the contents of castings protection, packaging, transportation and storage. This document is applicable to the production, inspection and delivery acceptance of low alloy steel castings for general engineering and structural use. |
| GB/T 15115—2024 | "Die cast Aluminum alloy" | This document specifies the grade and code of die cast aluminum alloy, technical requirements, test methods, inspection rules and marks, quality certificates, packaging, transportation and storage. This document is applicable to the production and inspection of die-cast aluminum alloy materials (aluminum alloy liquid and aluminum alloy ingots). |
| GB/T 43920—2024 | "General Technical Specification for concentrated melting and distribution of molten aluminum for die casting" | This document specifies the process specification, technical requirements, inspection methods and inspection rules for concentrated melting and distribution of molten aluminum alloy for die casting.
