Escopo e aplicabilidade

This standard specifies the safety technical specifications for the design, manufacturing, and acceptance of metalforming machinery. It applies to a wide range of equipment, including mechanical presses, hydraulic presses, screw presses, shearing machines, press brakes, and laser cutting machines. It does not apply to metalforming machinery manufactured before the implementation date of this standard.

Requisitos técnicos

The standard mandates a comprehensive risk assessment for all metalforming machinery, requiring hazards to be eliminated through intrinsic safety design first. It sets forth general safety requirements covering transmission systems, electrical, hydraulic, and pneumatic systems. Manufacturers must implement robust control and monitoring systems with redundancy and fault detection capabilities to prevent unexpected startups. For the working hazard zone, the standard specifies the mandatory use of safety protection devices such as interlocking guards, two-hand control devices, and electro-sensitive protective equipment (like photoelectric protection). These devices must be configured to ensure operators cannot reach the danger zone before hazardous motions cease. It also details requirements for robot systems, radiation, noise, and ergonomics. The core of the standard lies in its special safety requirements for 12 distinct categories of metalforming equipment. For instance, mechanical presses require strict monitoring of friction clutches, brakes, and overrun conditions, while hydraulic presses must have reliable hydraulic or mechanical support valves to prevent accidental gravity falls of the slide block. Each machine type has tailored operational and safeguarding criteria to address its specific mechanical dangers.

Métodos de ensaio

Compliance verification is conducted through visual inspection of components, performance and functional testing, and physical measurements using instruments. Design characteristics are also validated through drawing reviews and technical data calculations. Specific testing protocols are referenced from associated GB/T standards for components like photoelectric guards and control systems.

Perguntas frequentes

What products are regulated under GB 17120-2025?

It applies to the design, manufacturing, and acceptance of metalforming machinery, including mechanical presses, hydraulic presses, shears, press brakes, and laser cutting machines. It does not apply to metalforming machinery manufactured before its implementation date.

Are there any updates from the previous version of GB 17120-2025?

This new version consolidates and replaces several older standards (like GB 17120-2012, GB 6077-1985, and GB 28241-2012). It introduces updated requirements for control systems, adds specific safety requirements for various machine types, and includes new provisions for robotic systems and remote services.

How does GB 17120-2025 differ from ISO standards?

The standard incorporates safety principles aligned with ISO standards, frequently referencing GB/T 15706-2012 (which is identical to ISO 12100) for general machinery safety. However, it includes mandatory national deviations and highly specific technical requirements tailored to the unique hazards of metalforming equipment.
