GB/T 46074-2025 Safety of thermal cutting machines
Basic Information
Scope
This document specifies the safety requirements and inspection methods for thermal cutting equipment, including all aspects such as design, manufacturing, production, transportation, installation, maintenance, and after-sales service. This document applies to thermal cutting, marking, and line-drawing equipment that uses concentrated thermal energy to melt or burn materials, such as flame cutting, plasma arc cutting, and laser cutting. It is suitable for open gantry structures, cantilever structures, or cutting table structures with rail systems. This document does not include design standards for specific tools, such as oxygen and gas hose standards or electrical requirements for plasma power supplies. Most tools used on thermal cutting equipment have specific design and usage standards, and the associated risks from thermal cutting tools are governed by their respective standards. This document does not apply to handheld cutting equipment or small semi-automatic cutting equipment installed on workpieces with constrained trajectories and requiring manual operation, such as cart-type or simulation-type equipment. Except for laser position indication, the risks caused by laser radiation are regulated by GB/T 18490.1 and are not within the scope of this document.
