GB 24542-2023 is a current mandatory Chinese national standard for Fall protection—Guided type fall arrester including a rigid anchor line. It appears in the Medical compliance cluster with a product safety focus and has an implementation date of Jan 1, 2025.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to guided type fall arresters including a rigid anchor line designed for installation at an angle within 15 degrees from the vertical direction. It is mandatory for manufacturers producing fall protection systems for use in China. It covers the technical requirements, testing methods, and marking for these devices, which are critical components in personal fall arrest systems used in construction, industrial maintenance, and tower climbing. It does not apply to flexible anchor line systems.
Technical requirements
The standard specifies comprehensive design and structural requirements, mandating that the maximum rated load shall not be less than 100kg and that components must be free of burrs and sharp edges. Manufacturers must ensure the fall arrester has an automatic locking function and cannot rely solely on inertia. It defines strict static performance criteria, requiring the overall system to withstand a 15kN load without separation or fracture. Specific requirements are also set for energy dissipating elements and stop devices (Type A and Type B) to ensure structural integrity under load. The dynamic performance requirements limit the peak impact force to a maximum of 6kN and the fall distance to 1.2m, ensuring the test mass does not contact the ground. Operational performance must be verified under various conditions including forward, backward, lateral, and inclined states. Additionally, the standard outlines requirements for reliability through repeated locking tests, corrosion resistance via neutral salt spray testing, and locking performance in special environments such as extreme temperatures, water, oil, and dust.
Testing methods
Testing methods include Assembly Performance Test applying a 1kN lateral load to verify no separation or permanent deformation. Static Performance Tests apply specified loads (e.g., 15kN for overall, 2kN/22kN for buffers) for a set duration. Dynamic Performance Tests use a metal cylindrical test mass dropped in a free-fall state to measure peak impact force and fall distance. Operational Performance Tests simulate various falling postures (forward, backward, lateral, inclined) to measure locking and fall distances. Reliability Tests involve 1,000 consecutive drop tests with a 5kg weight. Corrosion Resistance Tests follow GB/T 10125 for neutral salt spray exposure. Special Environment Tests precondition the device in high/low temperatures, water, oil, or dust before conducting locking performance tests.
FAQs
What products are regulated under GB 24542-2023?
GB 24542-2023 regulates guided type fall arresters including a rigid anchor line. These are fall protection devices that slide along a rigid rail and lock automatically during a fall. It applies to systems installed within 15 degrees of the vertical direction.
Are there any updates from the previous version of GB 24542-2023?
Yes, compared to the 2009 version, this update adds requirements for assembly performance, overall static performance, and buffer device static performance. It also introduces new terms like maximum/minimum rated load and includes technical requirements for deflectors in Appendix B.
How does GB 24542-2023 relate to international standards?
The standard references concepts similar to those found in ISO 10333-4 and EN 353-1, which also cover vertical rail and guided type fall arresters. However, compliance with GB 24542-2023 is mandatory for products sold in the Chinese market, requiring specific testing and certification according to Chinese regulations.
The summary above provides a high-level overview of GB 24542-2023.
