GB 24538-2025 Fall protection—Energy absorbers English, Anglais, Englisch, Inglés, えいご
1 Scope
This document specifies the technical requirements, inspection rules, permanent marking, and information provided by the manufacturer for energy absorbers, and describes the corresponding test methods.
This document is applicable to energy absorbers used in high-altitude operations.
This document is not applicable to energy absorbers used in industries such as sports and firefighting.
2 Normative references
The following documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
GB 6095-2021 Fall protection - Personal fall protection systems
GB/T 10125 Corrosion tests in artificial atmospheres - Salt spray tests

GB 24543 Personal fall protection equipment - Lanyards
3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 12903, GB 6095-2021 and the following apply.
3.1
energy absorber
component that is connected in series between the harnesses and the anchor point to absorb the impact energy when falling
3.2
pin centre length
straight-line distance between the load-bearing points at both ends of the energy absorber (3.1)
Note: See Figure 1 for the schematic diagram for pin centre length of energy absorbers.
Figure 1 Schematic diagram for pin centre length of energy absorbers
3.3
permanent extension
difference in pin centre length (3.2) of energy absorber (3.1) before and after deployment in dynamic performance test
3.4
peak force
maximum impact force measured in the dynamic performance test
3.5
minimum rated load
minimum mass of operators specified by the manufacturer when the energy absorber (3.1) in use can induce braking and energy absorption
Note: It does not include the mass of tools and equipment carried, expressed in kilogram (kg).
3.6
maximum rated load
maximum mass that the energy absorber (3.1) can bear when in use as specified by the manufacturer
Note: It includes the dead load of operators and the mass of tools and equipment carried, expressed in kilogram (kg).
3.7
harness
component that holds the personal fall protection systems over the body to support and control the body in the event of a fall to disperse the impact
Note: Harnesses consists of webbing, buckle and other metal components. Generally, they are classified into full-body harnesses, single-waist harnesses and half-body harnesses.
