Talk:Gloss units

How big is a gloss unit?
It would nice if someone added a simple quantitative definition of a gloss unit in terms of percentage of reflected light, or, at least, an idea of which gloss is to be expected from a perfectly flat surface, or which is the standard and how many gloss units it has (100?). The ASTM ref is not freely accessible (and, anyway, I do not expect it to be simple). ---GianniG46 (talk) 10:06, 4 November 2010 (UTC)
