Testing: Abrasion Resistance

Written By: Lance Piatt

The other day while Craig and I were scripting out a new mini series we are planning, the topic of rope abrasion and how much of it is true and how much of it is a hoax came up?  Tough question right?  Sterling has long been a friend of the family and well, this evening I happened upon this article written up by Sarah Fleetwood of Sterling’s R&D Team.  They always put out great and useful content.  So I thought I would repost it for those who may not have seen it.  A great read.

Sterling is dedicated to producing the best possible product, and that means researching and testing our products thoroughly. Some testing is required for certification, but that’s only the beginning. We submit our ropes to a battery of tests, which simulate field conditions in a controlled environment, so we can have the highest level of confidence that they will perform when needed. The testing will vary depending on the questions we want to answer and the expected usage of the rope.

For years, we have known that the use of Technora® fibers in rope offered benefits in terms of strength and heat resistance. In addition, there was great evidence of increased longevity and resistance to cuts and abrasion damage that was more difficult to quantify. To prove greater durability, our engineering department devised the following test:

  • A mass of 315 lb was attached to the test rope.
  • This rope was run over a 150° bend, fitted with a steel file.
  • The other end was attached to our hydraulic tensile tester.
  • A load was raised up, dragging the rope 40 cm (160° bend) across the file, then lowered back to the ground. This process was repeated, with the file being cleaned every cycle until the core of the rope became visible.




We ran this test on a variety of ropes, but the benefits of the Technora fiber in the sheath were best shown in the following tests:

  • Our 9 mm HTP (polyester sheath) went through 9 cycles before the core was exposed. A similar diameter rope, our 9 mm C-IV, which has a Technora sheath, sustained 14 cycles on average.
  • Similarly, our 7/16″ HTP (polyester sheath) rope lasted an average of 15 cycles.
  • The Tech11, with a Technora sheath, went for more than 27 cycles before the core finally showed through. In high-abrasion environments, such as limbs and tree crotches, this durability keeps the equipment in service longer and provides a higher degree of safety.







Peace on your Days…

  8. Youre so cool! I dont suppose Ive learn anything like this before. So nice to search out any person with some authentic ideas on this subject. realy thanks for beginning this up. this website is one thing that’s wanted on the net, someone with a bit originality. useful job for bringing one thing new to the internet!

  9. Everything is very open with a very clear explanation of the challenges. It was truly informative. Your website is very useful. Thanks for sharing.

  10. Can I just say what a relief to find someone who actually knows what theyre talking about on the internet. You definitely know how to bring an issue to light and make it important. More people need to read this and understand this side of the story. I cant believe youre not more popular because you definitely have the gift.

  11. After I initially commented I appear to have clicked on the -Notify me when new comments are added- checkbox and from now on every time a comment is added I get 4 emails with the exact same comment. Is there a means you can remove me from that service? Thanks a lot.

  12. Good post. I learn something new and challenging on websites I stumbleupon on a daily basis. It will always be exciting to read through content from other writers and practice a little something from their websites.

  13. Hi, I do think this is an excellent web site. I stumbledupon it 😉 I am going to return once again since i have book-marked it. Money and freedom is the greatest way to change, may you be rich and continue to help other people.
