According to SCAQMD Rule 1113 it is difference in gloss: FLAT COATINGS are coatings that register a gloss of less than 15 on an 85-degree meter or less than 5 on a 60-degree meter. NONFLAT COATINGS are coatings that are not defined under any other definition in this rule and that register a gloss of 5 or greater on a 60 degree meter and a gloss of 15 or greater on an 85 degree meter according to ASTM Test Method D 523 as specified in paragraph (e)(6).

So essentially, we need to inquire from the manufacturer whether a paint / coating is Flat or Non-flat. Thanks Petr!
