Compliance overview
Scope and applicability
This standard specifies the safety technical requirements and measures for the design, manufacturing, supply, and use of cupolas and cupola charging machines. It is mandatory for all manufacturers and suppliers of these foundry melting equipments. It applies to the safety design, installation, and operation of these machines in the casting and metallurgy industries, referencing GB 5083 and GB/T 15706.1 for general safety principles.
Technical requirements
The standard outlines comprehensive mechanical safety requirements to mitigate risks such as rupture, crushing, and falling objects. It specifies material thickness for critical components like furnace shells and flanges, and mandates specific safety factors for wire ropes and support structures. Manufacturers must ensure structural integrity and implement reliable braking and locking mechanisms. Regarding electrical and thermal hazards, the standard requires compliance with GB 5226.1 for electrical systems and mandates proper insulation and pressure testing for water-cooled components. Equipment must be designed to prevent electric shock, lightning strikes, and burns from high-temperature surfaces. Warning signs for potential flame ejection and hot metal splashes are strictly required. The standard also addresses noise and material/substance hazards. It sets limits for equivalent continuous sound pressure levels and requires dust removal devices to control emissions during the melting process. Proper ventilation and explosion-proof measures must be implemented to protect operators from carbon monoxide and explosion risks. Ergonomic principles according to GB/T 16251 must be integrated into the design.
Testing methods
Compliance is verified through four primary methods: functional testing to check safety operations, instrumental detection for precise measurements, calculation or drawing review for structural stability and strength, and visual observation to ensure proper labeling, warnings, and usage information are present.
