Huh? Yo, don't be talking trash about KN or the Stones! You don't know us. You don't know what we are about. KN is respectable and involved so are we. Don't be spewing trash about good foulks. There is no need for stupidity like your teenage dumb ass in climbing. No need for it. There are plenty porn or dating sites outside of this. So scoot boy, scoot!

Yes we will! I'm curious myself. My bet is the sunlight exposed sling will go first...we shall see!

I agree, send those slings! Would be great to know how they tested, although I think I sometimes piss off 20kN with my nit-picky critiques of tests he posts on here. For instance.....

One test of each method (bleach, sunshine, gasoline, etc)... doesn't tell you anything. Analyzing breaking strength (or any other data for that matter) without stating confidence interval or standard deviation doesn't mean anything. You need to break enough samples of each to place confidence intervals around the result (e.g., 95% confidence that the sling has a breaking strength greater than 2000 lbs).

Please send 20kN at least 30 samples of each sling (bleach, sunshine, gas, etc). 30 of each should result in a nice, tight confidence interval.

I think Eric should supply the samples as well, I sent a few petzl attache Biners to 20kn to get tested and he did A+ work and was very prompt. Much appreciated 20kn!

We will send 1 sling washed and dried multiple times. We will wash it in tide in hot water then dry it on hot setting. We are not paying for laundry machine or water so I think it's fair. I think everybody should send him at least one sample of sling with the description of what was done to it. Then he will post the findings here for everyone to see and compare.

Ellenor, maybe you should send ALL your climbing and internet gear to 20kn to test. You could have inadvertently splashed something on your rope, cams, nut tool, shoes, harness, computer, keyboard, smartphone, etc.

Just trying to help, you can never can be too safe.

Yo wtf? He ain't broke!

Did you wash them with hot water, cold water, white gas, or kerosene? It makes a difference.

Good idea, send Ryan in for destructive testing...I'll bet he can tolerate more than most of us!

Hehehe I keep the ginger bread man and do my own destructive testing on him ;)
He can endure quite a bit I tell ya...;)

You dont piss me off. I like constructive criticism. Without it I dont really learn anything.

If I am writing a formal study, or I am trying to observe a phenomenon that is hard to analyze (e.g. compound pulley efficiency), or I am observing data with a high deviation, then I agree that I need to capture many samples and analyze them as a whole. I would have liked to do more tests on the EDK myth, but I ran out of rope so I published what I had. But I agree that I should have pulled some more samples.

However, there are some scenarios in which I believe that one or two data samples are sufficient for a general conclusion. For example, say I want to determine if sulfuric acid really damages nylon (bear with me). So I spill a few drops of diluted sulfuric acid on a sling, I test it, and holy shit, my brand-new 22kN-rated sling failed at 4kN. At that point I don't think I need to test any more samples to conclude that sulfuric acid does indeed damage nylon.

Now if I want to learn the degree to which sulfuric acid damages nylon (as you mentioned), then sure I would need to test many samples under many different conditions, calculate the SD and plot the data on a nice Excel chart to analyze. No argument there.

Alot of these post that say I never wash my ropes or ECT. You must be made of money. By washing your climbing ropes obviously by hand (never machine wash in my opinion even if front loader) you lengthen the life of your rope. Those small unseeable little gains of sand, dirt, batshit, and other natural abrasive materials dislodge themselves from between the nylon prison that they were once trapped. Regardless of knowing that a majority of us put our ropes I'm out mouths while clipping, I must add I don't want all that dirt and bat shit in my mouth. So save yourself money and langthen the life of your rope. The stuff's not biodegradable so the longer you keep it the better off the planet is.

In the six years since this post had its last reply, the OP's account has been deactivated.

In other words, why are you replying to a six-year old thread?

Edit: The infamous Eleanor was the OP.

You should have your account deactivated for resurrecting a Hellenor thread.

Do you and Marc get together to decide who's going to paste this reply?

Yeah, neither of us would back down on this one, so we tag teamed it.
