Which term describes rope that has less than 1% stretch?

The term that describes rope with less than 1% stretch is "super static." This classification indicates that the rope is designed to minimize any elongation when under load, making it ideal for situations where you need a high degree of stability and control, such as in rescue operations or industrial applications. Super static ropes provide a firm and secure method of anchoring or lifting, where any significant stretch could lead to dangerous situations.

Dynamic ropes, on the other hand, are specifically engineered to absorb shock loads, designed for climbing where falls are possible. These ropes stretch considerably more than 1%, which is beneficial in reducing the impact force on both the climber and the protection systems.

Standard ropes can vary in stretch characteristics but do not necessarily fit into the specific criteria of either super static or dynamic. Elastic ropes refer to materials that inherently stretch, but they do not specify the extent or application like the term super static does.
