Howdy all.
Has anyone here had any experience with using older TC wire , i.e. stuff that's been sitting around in storage for some unknown time? I need to instrument a test bed for some fire testing (using a JP-8 pan fire), and have been trying to keep costs to a minimum due to recent budget issues. I found a couple of rather large spools of K-type fiber insulated TC wire sitting out in a shed at the test site, so they were out of the rain but not temperature or humidity controlled.
I've found some good information from Sandia, NASA, NIST, ORNL, etc. about TC time-dependent degradation and accuracy at elevated temperatures, but can't readily find anything about stuff stored at normal temperatures. There was no obvious signs that the spools themselves had water sitting on them or anything like that, but I cannot be certain that they never got wet.
Am I better off assembling the whole thing (and maybe using a TC calibrator for verification), or should I just scrap it all and buy new?
