1.4 Floor Sink As covered in this Standard, a floor sink is a receptor drain that is designed and installed for the purpose of draining indirect waste to the sanitary drainage system. 2 GENERAL REQUIREMENTS 2.1 Materials 2.1.1 Enameled and Epoxy-Coated Cast Iron Floor Sink. The enameled and epoxy-coated cast iron floor sink shall conform to the general requirements outlined in ASME A112.19.1/CSA B45.2-08, Section 4, and surface shall be examined for blemishes in accordance with para. 5.2. 2.1.2 PVC Plastic Floor Sinks. PVC floor sinks shall be made of a single PVC virgin compound except as provided in para. 220.127.116.11, and shall conform to the requirements specified in ASTM D 1784 for a PVC 12454 compound. The PVC plastic floor sinks shall conform to the general requirements outlined in IAPMO/ ANSI Z124.6-2007, Section 2 and workmanship and fin- ish in Section 3. 18.104.22.168 Reworked Plastic. Clean, reworked plastic generated from the manufacturer’s own PVC 12454 products may be used provided the floor sinks produced meet the requirements of this Standard. 2.1.3 Stainless Steel FloorSinks. The stainless floor sink shall conform to the general requirements outlined in ASME A112.19.3/CSA B45.4-08, Section 4, and surface shall be examined for blemishes in accordance with para. 5.1. 2.2 Epoxy Coating The visible surface after installation of each floor sink shall be acid-resisting epoxy, thoroughly fused to the cast iron base. It shall be free from flaws that may affect the appearance or serviceability of the floor sink. The epoxy surface shall meet the requirements of ASME A112.19.1/CSA B45.2-08, para. 4.1.2 when evalu- ated for surface defects in accordance with para. 5.2.
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 catching surfaces. Drains and other waste-fitting compo- 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 shall com- 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 conform to 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.
