FYI an addenda to 2009 includes some important updates to EQc4.3:

“Mineralbased finish flooring products such as tile, masonry, terrazzo, and cut stone without integral organic-based coatings and sealants and unfinished/untreated solid wood flooring qualify for credit without any IAQ testing requirements.”
