What is the minimum test load for ascending devices intended for light use?

The minimum test load for ascending devices intended for light use is established at 5 kN. This requirement ensures that the devices can safely handle the forces they might encounter during typical operations. Light use refers to scenarios where the loads are not excessively high, which is common in many personal and recreational climbing or rescue situations.

The selection of 5 kN as the minimum test load aligns with international safety standards that outline the necessary strength for climbing and rescue equipment to ensure reliability and safety during ascents. This value provides a balance between safety and practicality, ensuring that the devices can withstand the operational stresses without being unnecessarily heavy or cumbersome.

In contrast, higher test loads such as 8 kN or 10 kN are more applicable to ascending devices intended for heavier use or in industrial applications where the forces encountered could be significantly greater. The lower value of 3 kN does not provide adequate assurance of safety for typical light-use scenarios, which is why it is not the minimum requirement for these devices.
