HI Juliano! The limits in the IPC JSTD 006 specification are for virgin solder bar purchased from a solder alloy supplier and the limits in the IPC JSTD 001 specification are for soldering processes - one column is for preparation solder pots (pretinning, solderability testing, etc.) and one is for assembly solder pots (wave, selective, etc.). You should be using the IPC-JSTD-001 solder pot contamination limits.
