How do you test your ropes? Mostly testing seems to involve destroying (part of) them.
Hi
Our drop testing is carried out by submitting 2.5 metre samples of rope to the BCA along with all relevant data i.e. age, make, type, usage, storage, washing details etc. This is done after about 5 years of use (or sooner if the rope has had heavy useage) by providing an end sample and then re-marking that rope with it's new reduced length. In addition, any rope that is retired from use will have a centre and end section submitted for testing. Retirement may be due to obvious wear and tear, age of rope, number of trips it's been used on or following the results of drop tests.
Since 1989 we've been keeping detailed records for all ropes - make, length, diameter, purchase date and trip details - dates, cave/pothole name and number of people using the rope on that trip. New ropes are purchased as required to maintain our stock levels of the various length ropes.
