It was in the trunk.

...I've NEVER seen fumes, visible or otherwise, above sulfuric acid in my 30+ years as a chemist. Tell us now...have you?

There are fumes above some acids: hydrochloric, nitric, or oleum. But not above aqueous H2SO4 i.e. car battery acid...

Are you really a chemist, or did you merely stay at a Holiday Inn Express last night? I suggest you go back and look at the equilibrium vapor pressure of sulphuric acid around room temperature.

AND DUDE, LOOK UP THE WORD "CONTEXT."

Also, fuck you dude, I live in Montana, don't talk to me about COLD - you illiterate poser twit.

The other concern, however, is dapness and humidity - and since the winter is usually a 'dry' time of year - it seems, to me, that you've lucked out on this one as well.

Battery acid contact is a potential threat to ropes, but you needn't make up stories to get the point across.

from the tradgirl site:
Standing on a rope in the snow with crampons did no damage


what? you mean puncturing your rope with the points on your crampons doesn't damage it? this makes little sense to me, but "on snow" i guess so it sinks in i suppose

As for Pit and his testing, I'd like to read more of the details about exactly what he was testing. I stated this in another post somewhere on here yesterday... Rope is extremely strong and can withstand about twice the force that the human body can (based on testing done on parachuters... which says the human body's limit is around 12kN). So even a really warn out rope that originally rated at 25kN+ will still probably hold the 12kN... that's if you can even handle that much. It's not so much the strength of a rope that would worry me in most situations, it's the elasticity of it.
Did Pit only test the breaking strength of ropes he tried to damage? Although the strength might not have been effected that much it might have effected it's ability to absorb some of that impact force when you fall, the difference of subjecting your body to 9kN instead of only 6kN. Static line is definitely strong enough to climb on too, but would you want to take a 30ft whipper on it?

here's something else: was your rope wet when you stored it in the trunk? if so, if it's freezing where you are in winter than the water would turn to ice and could damage the rope

Where did you get this BP data? I have found 327 C according to the MSDS data , and 280 C according to chemfinder.com, but the only place I have been able to find 338 C is wikipedia.... which I wouldn't base any of my chemical information off when I go to lab... and my labs have to be exceedingly less important than lab work an actual chemist does.

I say to the OP, just buy another rope... spend $150... it'll end any question in your mind.
If not... just climb on the rope and don't worry.

If you have VP data, please share it. The b.p. is 338 C, which by conventional volatility correlations equates to "no vapor pressure".

This is a PDF directly from the uiaa website.
to quote it:

"Nylon is UV Stabilized"
ie...UV will not damage your rope... unless it's from the 1960's... in which case, you should retire it anyway.

Well, since you are a "chemist," I'm sure you know that the boiling point of any liquid merely represents the temperature at which the vapor pressure over the liquid equals atmospheric pressure. Surely you're not claiming that liquids have "no vapor pressure" below their boiling points, are you? As I'm sure you can appreciate, that would be a highly ignorant position to take.
