2.2.1 Surface Epoxy. The surface epoxy, visible after installation, shall be glossy to the extent that it will have a 60 deg (1.05 rad) specular gloss of not less than 60 when tested in accordance with para. 5.2.
2.2.2 Epoxy Thickness. The thickness of the epoxy coating, as measured on a flat surface at least 1 in. (25 mm) from any edge shall be not less than 4 mils (0.1 mm).
2.2.3 Acid Resistance. The epoxy coating shall be acid resisting when tested in accordance with para. 5.3. 2.2.4 Epoxy Flexibility. The epoxy shall be flexible when tested in accordance with para. 5.4.
2.3 Detail Requirements
2.3.1 Floor Sink Drain Body. The drain body shall be smooth with rounded corners to eliminate bacterial catchingsurfaces. Drains and otherwaste-fittingcompo- nents shall comply with ASME A112.18.2/ CSA B125.2-05.
2.3.2 Strainers and Grates. The strainers and grates shall be accessible and removable for cleaning and main- tenance. The grates must be aligned properly and fas- tened by accompanying screws, unless floor sink design is for loose set installation. 2.3.3 Open Area. The grates and strainers shallcom- ply with the open area requirements of ASME A112.6.3-2001.
2.3.4 Screws. All screws shall be made ofcorrosion- resistant material.
2.3.5 Dimensions. PVC floor sink dimensions shall conformto the socketand spigotdimensions as specified in ASTM D 2665. 2.3.6 Top Loading. Top loading classifications for grates shall be in accordance with ASME A112.6.3-2001.
2.4 Fixture Fittings Factory-supplied supply fittings shall comply with ASME A112.18.1/CSA B125.1-05. 2.5 Fixture Waste Fittings Factory-supplied waste fittings shall comply with ASME A112.18.2/CSA B125.2-05. 3 FLOOR SINK TYPES AND SIZES 3.1 Illustrations The floor sink type and sizes illustrated in Figs. 1 through 4 are commonly cast iron and Figs. 5 through 7 are commonly PVC, but other type materials may be provided. Those illustrated represent a selection for ordinary types and may be provided with a variety of 2 tops. Top grates shall meet the requirements of ASME A112.6.3-2001.
3.2 Floor Sinks Without Anchor Flanges Floor sinks without anchor flanges are for use where anchoring or clamping of a waterproof membrane is not required.
3.3 Floor Sinks With Anchor Flanges Floor sinks with anchor flanges are for use where anchoring or clamping of a waterproof membrane is required. The membrane is to be secured to the anchor flange with flange clamps. Provisions shall be made in the drain body for weepholes. They shall be cast in the cast iron body and drilled in the PVC body, if necessary (see Figs. 5 through 7).
3.4 Grate Configurations Grate configurations shall be either full, 3 ⁄ 4 , or 1 ⁄ 2 design. See Figs. 8 through 10. Direction of slots may vary depending on the manufacturer.
4 OUTLET SIZE AND CONNECTION Outlet size and connections shall be in accordance with ASME A112.6.3-2001 and/or ASTM A 888. PVC shall also be in accordance with ASTM D 2665.
5.1 Enameled Cast Iron Floor Sinks Enameled cast iron floor sinks shall meet the require- ments of ASME A112.19.1/CSA B45.2-08.
5.2 Specular Gloss of the Epoxy Coating The specular gloss of the epoxy shall be determined in accordance with ASTM D 523 for 60 deg (1.05 rad).
5.3 Acid Test for the Epoxy Coating The acid test for the epoxy coating shall be a fresh solution made of one part citric acid crystals to ten parts water by weight applied to the surface of the epoxy coating for 15 min, at the end of which period, after washing and drying, there shall be no loss of epoxy. The floor sink and acid solution shall have been stored for not less than 3 hr immediately preceding the test in an atmosphere of 80°F ± 10°F (26.67°C ± 5.55°C). The test shallbe applied to a cleanarea, ina pool ofseveraldrops, and covered with a watch glass to hold the solution in place.
5.4 Flexibility of the Epoxy The flexibility of the epoxy shall be in accordance with ASTM D 522, 180 deg around a 1 ⁄ 4 in. (6.4 mm) mandrel.
