Compliance to the above specifications is based upon testing according to the
Cordage Institute Standard CI 1801. As performed by Underwriters Laboratories.
Weights - Are average and may vary +/- 5%
Tensile strengths - Are 3 Sigma minimums for new, unused ropes as tested by
Underwriters Laboratories.
Very little degradation from UV. Can be used outside over long term if inspected regularly. All synthetic fibers are prone to some degradation due to prolonged exposure to UV radiation. When ropes are not in use, store them in a cool dry location away from direct exposure to sunlight.
Good resistance to most minerals / organics, acids, weak alkalis, bleaches and other oxidizing agents and most solvents. Polyester is generally considered to have a better overall resistance to acids or oxidizing agents. Nylon is preferred when exposed to alkalis.
Melting point of 480 F, progressive strength loss above 300 F,
Good resistance to the passage of electrical current. However in rope form, dirt, surface contaminants, water entrapment and the like can significantly affect dielectric properties. Extreme caution should be exercise any time a rope is in the proximity of live circuits.
Recommended D/d ratio is 8:1
No blanket working load recommendation can be made because it depends on the application and conditions of use, especially potential danger to personnel. It is recommended that the user establish working loads and safety factors based on professional and experienced assessments of risks. The working load is a guideline for the use of a rope in good condition for non-critical applications and should be reduced where life, limb, or valuable property is involved, or exceptional service such as shock, sustained loading, severe vibration, etc. The Cordage Institute specifies that the Safe Working Load of a rope shall be determined by dividing the Minimum Tensile Strength by the Safety Factor. Safety factors range from 5 to 12 for non-critical uses, 15 for life lines. SLK= Minimum Break Strength / Safety Factor
Can be Urethane coated to improve abrasion resistance, UV resistance and to create a water barrier.
Available in White (blue tracer), Black, Orange, Blue, Red
