Part 41 Work Requiring Rope Access

Section 818 Standards for high stretch (dynamic) rope

For compliance purposes, the rope must bear the mark or label of a nationally accredited testing organization such as CSA, UL, SEI, etc. as evidence that the rope meets the requirements of at least one of the listed standards. Rope bearing a CE mark is considered acceptable for the purpose of this Code, as is rope bearing the UIAA label. The CE mark – Conformite Europenne – indicates that the company manufacturing the product has met the requirements of one or more European directives. A UIAA label cannot be used unless the rope already bears a CE mark.

CEN Standard EN 892

CEN Standard EN 892: 2004, Mountaineering equipment. Dynamic mountaineering ropes. Safety requirements and test methods, specifies safety requirements and test methods for dynamic rope (single, half and twin ropes) in kernmantle construction for use in mountaineering, including climbing. Dynamic mountaineering rope is defined by the Standard as rope that is capable of arresting the free fall of a person engaged in mountaineering or climbing with a limited peak force.

Dynamic rope has the following performance characteristics:

  • static elongation must not exceed 10 percent in single ropes, 12 percent in half ropes, and 10 percent in twin ropes
  • dynamic elongation cannot exceed 40 percent during the first drop of each test sample
  • the peak force in the rope, during the first drop for each test sample, must not exceed 12 kN in single ropes, 8 kN in half ropes, and 12 kN in twin ropes
  • under test, slippage between the sheath and core must not exceed 20 mm.

UIAA Standard 101

UIAA Standard 101: 2004, Mountaineering and Climbing Equipment – Dynamic Ropes, requires that the rope meet all the requirements of CEN Standard EN 892 plus an additional requirement for slippage.
