Compliance overview
Scope and applicability
This standard specifies the technical requirements, inspection rules, permanent marking, and manufacturer-provided information for guided type fall arresters including a flexible anchor line. It applies to these devices when installed within a 15-degree angle from the vertical direction. It is mandatory for manufacturers of flexible anchor line fall protection systems targeting the Chinese market. The standard replaces the previous GB/T 24537-2009 and introduces significant updates to definitions and testing protocols.
Technical requirements
The standard outlines comprehensive design and structural requirements to ensure safety and reliability. Key aspects include mandating a minimum maximum rated load of 100 kg, requiring smooth surfaces without burrs, and restricting the connecting line length to a maximum of 1 m. Manufacturers must ensure the arrester features an automatic locking function rather than relying solely on inertia. The standard also specifies requirements for components like the flexible anchor line (e.g., minimum 8 mm diameter for wire ropes) and connectors, which must comply with GB 23469. Regarding static performance, the device must withstand specific load thresholds without separation, opening, or fracture of any components. This includes overall static strength, energy dissipating element performance, and anchor line strength for fiber ropes or webbings. The overall system must endure a 15 kN load without failure. For dynamic performance, the standard sets limits on peak impact force and arrest distance to prevent the test mass from contacting the ground. Additionally, the device must demonstrate high reliability by successfully locking over 1,000 consecutive test drops. Products must also pass corrosion resistance tests and, if declared suitable for special environments, meet locking performance criteria under extreme conditions like high temperature, low temperature, water immersion, oil immersion, and dust exposure.
Testing methods
Testing procedures encompass visual and tactile inspections for design compliance, followed by climbing tests using personnel within specific height and weight ranges. Static performance tests evaluate the overall system, energy dissipating elements, and the anchor line under sustained loads using calibrated force application equipment. Dynamic performance testing utilizes a rigid structure, a release device ensuring zero initial velocity, and a metal cylindrical test mass with dynamic force and distance measurement sensors. Reliability is verified through 1,000 repetitive drop tests, while corrosion resistance is assessed via a neutral salt spray test according to GB/T 10125. Special environment performance involves pre-treating samples under extreme conditions before conducting locking performance tests.
FAQs
What products are regulated under GB 24537-2025?
GB 24537-2025 regulates guided type fall arresters including a flexible anchor line, which are components of fall protection systems used within 15 degrees of the vertical direction.
Are there any updates from the previous version of GB 24537-2025?
Yes, this standard replaces GB/T 24537-2009. Key changes include updated definitions, the addition of terms like energy dissipating element and locking distance, revised static and dynamic performance requirements, and new testing methods for special environments.
How does GB 24537-2025 relate to international standards?
The standard references concepts found in international and regional standards such as ISO 10333-4:2002 and EN 353-2:2024, but it establishes specific mandatory technical requirements and testing protocols for the Chinese market.
