4.4.4 Enamel thickness
The thickness of the enamel, measured on a flat surface at least 25 mm (1.0 in) from any edge of the fixture, shall be at least 064 mm (0.025 In) for cast Iron and 0.13 mm (0.005 in) or steel.
4.4.5 Surface treatments
Belore they are enamelled, surfaces shall be treated with ground coat. After enamelling, any surface subject to rework that exposes base metal shall be factory treated with rust inhibitor. All other steel surfaces shall be treated with at least one coat of filler, ground coat, or paint.
