A durability test is highly relevant, as information about rope performance is usually only available for new rope.
To give buyers of Prorope rope a clear picture of the quality, we want to know how much strength the rope retains after being exposed to outdoor conditions for a given period.
The rope is unused, but is exposed to:
- rain
- sun
- wind
- temperature fluctuations
The rope samples are kept outside 24 hours a day, 365 days a year. You can see this here:
Below you'll find the results:
| Description | Date | Average breaking strength |
| Baseline test (new rope) | May 2026 | 1827 kg |
| 6 month test | November 2026 | coming soon |
| 12 month test | May 2027 | not yet available |
| 2 year test | May 2028 | not yet available |
| 3 year test | May 2029 | not yet available |
| 4 year test | May 2030 | not yet available |
| 5 year test | May 2031 | not yet available |
The average breaking strength is based on 5 individual tests. Example:
For the 6-month test, we take 5 of the 30 samples stored outside and test each one for breaking strength.
The average of these 5 tests is the value listed under "average breaking strength".
All rope samples are stored at a test site in Heibloem, the Netherlands.
Tests are carried out by Otto Tromm, who is responsible for all rope testing at Prorope.
