Compliance overview
Scope and applicability
This standard applies to ironworkers and related multifunctional machinery, including single-end punchers, double-end punchers, structural shearing machines, notching machines, and coping machines. It specifies general safety requirements, safety guard requirements, and safety protection requirements for working danger zones. This standard is mandatory for all ironworkers manufactured or imported into the Chinese market.
Technical requirements
The standard specifies general safety requirements for ironworkers, focusing on the strength, rigidity, and stability of main parts to prevent breakage or fracture during operation. It mandates proper guarding of moving parts to minimize injury from released mechanical energy and requires redundant electrical systems (compliant with GB 5226.1) to prevent unexpected stroke actions. It outlines strict stroke control requirements, mandating anti-repeat functions and reliable mechanisms to prevent unintended slide movements. Additionally, the counterbalance system must be specifically designed to ensure the slide or blade holder cannot fall in the event of component failure or pressure loss. Manufacturers must ensure pneumatic and hydraulic systems incorporate safety measures against sudden pressure loss or supply interruption. The standard details the configuration of safety guards, including fixed, interlocked, adjustable, photoelectric, and presence sensing devices. It establishes the relationship between permissible safety openings and their distance from the working danger zone, though the specific numerical parameters are provided in the full document. For the working danger zone, the standard specifies distinct safety protection measures for punching stations, structural shearing stations, flat shearing stations, and coping stations. Each station must be equipped with at least one of the prescribed safety devices and utilize warning colors or signs on working parts (per GB 2893 and GB 2894).
Testing methods
Compliance evaluation involves inspecting the mechanical structural integrity, stroke control mechanisms, and counterbalance systems. Testing procedures include verifying the safety responses of pneumatic and hydraulic systems, assessing the effectiveness of safety guards, and ensuring noise levels meet the referenced limits of GB 24389. Functional testing of electrical safety systems is also required to confirm redundancy mechanisms.
