We undertook a small product survey in which we purchased a range of brand-styles at retail and sent them to commercial laboratories for dimensional and physical tests, including banded and nonbanded area porosities. Other analyses obtained used chemical, chromatographic, and spectrophotometric (FT-IR) techniques to identify main banding agents and additives used with them. One finding from this study was at least at the time the samples were collected, some companies used just one FSC paper for all products while others used multiple FSC papers.<br>
