Throttle Cable Corrosion Testing
Throttle Cable Corrosion Testing
(OP)
I am investigating using a throttle cable for a certain application. It is critical that the cable operate with a puling force. The cable may be at rest for up to 25 years in a variety of installations. Although the cable will be inside a conduit, the conduit has a small opening (1/16" wide across a 3/4" diameter) exposing the cable to the elements.
I am looking for ASE, ASTM, or the like tests to subject the cable to prove out it's corrosion resistance. The cable is currently specified to be 304 stainless steel housed in a stainless sheathing. I thought automotive brake or throttle cable would be ideal or perhaps marine throttle cable.
I look forward to seeing feedback.

How much force? Low much can it change? Low long is the cable? What exposure?

25 years is a long long time to rely on a few thin strands. If you can completely house it, avoid air flow around it and coat the thing in marine grease, including down the actual casing. This is how it is done in the marine industry but nothing is expected to work for 25 years. Nothing critical anyway.

By the way, my situation better replicates the conditions of a throttle cable without the excessive underhood heat. Not directly exposed to splash.

I don't know about regulations since I was never involved in the manufacture or testing of such things.

The components will be corrosion resistant. I may take it to the extreme and coat stainless cable with teflon. My largest issue at the moment is determining the corrosion tests to prove it out. I am currently looking into a 30 day SO2CO2 and 10 day 20% salt spray. Will this be enough? I was interested in the tests that outboard motor companies use to prove out their cabling throttle systems.

IMHO your time would be better used prowling industrial junkyards and old installations of infrequently used equipment, studying and photographing how time has ravaged a lot of good ideas, and paying extra close attention to the population of mechanisms found still operable.
I think that within that latter population you will find a lot of large clearances and hot-dipped zinc. ... but you should check.
