How is static rope defined according to the cordage institute?

The definition of static rope, as described by the Cordage Institute, emphasizes that it has a controlled elongation under load, specifically between 1% to 6% when subjected to up to 10% of its breaking strength. This characteristic is crucial for rescue operations and other safety applications, as it allows for better control and stability when working in scenarios where sudden movements or excessive stretching could lead to dangerous situations.

Static rope is designed to minimize the amount of stretch, making it ideal for climbing, rescue, and rigging applications where stability is critical. The measured elongation ensures that there is some degree of flexibility, which can help absorb shock but does not compromise safety or control during rescue operations.

In contrast, other options refer to characteristics that do not align with the definition of static rope, such as having no elongation at breaking point or the ability to stretch significantly under load, which pertains more to dynamic ropes designed for shock absorption during activities like rock climbing.
