Filler metal/flux expiration?

Depends on the type of work....."most" of the seismic provisions have exposure limits on FCAW wires and SAW fluxes, otherwise, I doubt that you will find anything in the AISC manual.

Well everything in our shop is a H8 filler and we do a lot of SLRS work and we have a AISC audit next tuesday/wednesday and I am trying help by making sure nothing is expired.

AISC Specification 360-05, Section A3 para 5 references AWS A5.1 thru A5.32 for filler metal and flux for welding.

AISC Specification 341-05 Siesmic Provisions, Appendix W covers welding but is primarily concerned with just welding and I don't see any reference to filler metals or flux. Section W6.2 addresses filler metal packaging but the rest just seems to be welding performance requirements. Appendix X also covers welding. X1 references AWS A5.01, ABS (American Bureau of Shipping), Lloyds Register of Shipping, ASME, US Dept. of Defense, or a quality assurance program acceptasble to the engineer of record.

Lets make sure we clarify our terms. We talking atmospheric exposure limits or 'expiration' as I assume you intend?
To my knowledge there is no expiration on fluxes as long as they are cared for properly.

The manufacturer lists a maximum exposure time once the container is opened. For example, my 60# spools of FCAW have 7days after the bag is opened. I have spoken to them and they told me it's actually good for longer, but due to differenent enviromental conditions and locations the average is 7 days.

Now this is different than an unopened container. In general if its unopened there is no time limit, and long as its not damaged or the seal isn't broken.
