What is the minimum test load that light use DCDs must withstand?

The correct answer reflects the industry standard that dictates the minimum test load for light use descent control devices (DCDs). Light use DCDs are designed for specific applications, and their minimum load requirement is established to ensure they can safely accommodate the forces exerted during rescue operations or other uses experienced in the field.

A minimum test load of 13.5 k/N is specified to provide a safety margin, ensuring that these devices will perform reliably under operational conditions. This standard helps to prevent equipment failure and ensures that the device can reliably support the weight of a user, along with any additional loads that may occur in dynamic scenarios. This is crucial for the safety of both the rescuer and the person being assisted, making adherence to these standards an essential part of training and operational protocols for technical rescues.

In contrast, lighter test loads, such as those proposed in the other options, would not meet the safety and efficacy requirements for operational use and could lead to hazardous situations in the field.
