適用範囲

This standard specifies the safety management requirements for magnesium alloy high-pressure die casting and semi-solid die casting production processes. It is applicable to facilities involved in the die casting of magnesium alloys, covering plant layout, equipment safety, and operational procedures. Non-compliance will result in regulatory failure for manufacturers operating in the Chinese market. It replaces the previous edition GB 26488-2011.

技術要求

The standard outlines general safety requirements, including the simultaneous design of safety facilities with main engineering projects. It details plant layout and building structure standards, emphasizing fire prevention and structural protection in molten metal and dust explosion hazard areas. Facilities must ensure strict separation of molten metal operation areas from personnel gathering places. Regarding equipment and facility safety, the standard specifies requirements for magnesium alloy melting furnaces, die casting machines, and hydraulic systems. It mandates the installation of leakage monitoring, overheat protection, and emergency cutoff devices for furnaces. Additionally, it sets specific safety devices for cleaning, grinding, and machining equipment to mitigate dust explosion risks. Operational safety requirements cover furnace operations, die casting, cleaning, and machining processes. It details strict protocols for deslagging, empty shot testing, and confined space operations. The standard also introduces energy medium safety requirements, including gas pipeline monitoring and emergency cutoff mechanisms. Operators must adhere to strict personal protective equipment (PPE) and work approval systems. Compared to the replaced version, this edition introduces safety requirements for semi-solid die casting processes, major hazard source management, and the application of new technologies. It also adds verification methods to ensure compliance through documentation and on-site inspection.

試験方法

The standard outlines verification methods through a combination of documentation review and on-site inspection. Compliance is verified by examining project construction materials, training records, emergency plans, and equipment maintenance logs. On-site inspections are used to verify equipment safety markings, facility layout, and operational compliance. Enterprises must maintain comprehensive records of all safety management and equipment inspections for auditing purposes.

よくある質問

What products and processes are regulated under GB 26488-2025?

It applies to the safety management of magnesium alloy high-pressure die casting and semi-solid die casting production processes, including associated equipment, facilities, and operational procedures.
