Is there a standard (IPC, JEDEC, JEITA, etc) covering the tolerances on percentages of Sn, Ag, and Cu in SAC305? I'd also be interested if there are standard allowable amounts of other contaminants. I couldn't turn up anything in a search of the IPC and JEDEC sites, but that is probably my poor search skills.

I think you might be looking for J-STD-006. Here is a link to the table of contents: http://www.dynamixtechnology.com/docs/j-std-006as.pdf
