/ Lifespan of a rope
That aside, he's said the ropes are "about 10 years old". On the Beal website it says a rope should be retired after 10 years.
Why is this? And how long have you been using your ropes?
Most companies have a 10 year shelf life to take into account uv degradation, etc.
You can google most manufacturers and they all say the same thing, in essence...
10 years no use
5 years infrequent use
1-2 years moderate use
6 months heavy use
I eventually made a mate retire a rope after about 16 years weekly active service at a local wall when it made a funny creaking noise at the top of a route.
To the OP , the materials ropes are made of are quite stable if stored in a dark,dry, room temperature environment away from the chemicals that harm them (acids, certain solvents) There is no reason if a rope has been well stored that it should deteriorate to a point it should be retired.
A little note on UV.
ropes have been UV stable for some time (since mid 80's if memory serves correctly)now and the only effect is discolouration.
Yes I know they still put that on their advice. strange really when the BMC have done studies into this. look at their website.
When i was doing my MIA lecture research I also found some info on other chemical effects.
My favourite was that suntan cream actually made the rope a touch stronger!
