Coating Thickness: For acceptance purposes, at least 90 % of all coating thickness measurements after curing shall be 175 to 300 μm [7 to 12 mils] for bars sizes Nos. 10 to 16 [Nos. 3 to 5] and 175 to 400 μm [7 to 16 mils] for bar sizes Nos. 19 to 57 [Nos. 6 to 18]. A finding that more than 5% of the coating thickness measurements are below 125 μm [5 mils] shall be considered cause for rejection. The upper thickness limit shall not apply to repaired areas of damaged coating.
