Rope Testing - Long Term Rope Test

If you ask around, many cavers will say that an SRT rope is good for further use if it survived 2 drops on the NCA’s Rope Test Rig. However, the British Standard specifies that the rope, when new, should survive at least 5 drops. Some years ago, NCA purchased a long length of rope to conduct some test on the effect of usage. This length of rope was divided up into seven pieces each of around 30 metre long. Samples for testing were taken from each of these seven pieces for immediate testing. The seven pieces were then loaned to a number of clubs who were to use the rope for a specific number of usages before returning it for drop testing. The attached adobe PDF document gives some early results.
