Walnut Drive, Walnut, CA 91789-2825 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 Floor Sink The floor sink shall conform to the general require- ments outlined in Section 4 and surface shall be exam- ined for blemishes in accordance with Section 6 of ASME A112.19.1. 2.1.1 Floor Sink Drain Body. The drain body shall be smooth with rounded corners to eliminate bacterial catching surfaces. 2.1.2 Plastic Floor Sinks. The PVC plastic floor sinks shall conform to the general requirements outlined in Section 2 and workmanship and finish outlined in Section 3 of ANSI Z124.6. 2.1.3 Strainers and Grates. The strainers and grates shall be accessible and removable for cleaning and maintenance. Grates must be aligned properly.
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 effect the appearance or serviceability of the floor sink. The epoxy surface shall be examined for blemishes in accordance with Section 6 of ASME A112.19.1. 2.2.1 Surface Epoxy. The surface epoxy, visible after installation, shall be glossy to the extent that it will have a 1.05 rad. (60 deg.) specular gloss of not less than 60 when tested in accordance with para. 5.2. 2.2.2 Epoxy Thickness. The thickness of the ep- oxy coating, as measured on a flat surface at least 1 in. (25 mm) from any edge shall not be 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 flexi- ble when tested in accordance with para. 5.4. 2.3 Detail Requirements for PVC All floor sinks plastic parts shall be of PVC material. 2.3.1 PVC Floor Sinks. All PVC floor sinks shall be made of a single PVC virgin compound except as provided in para. 2.3.2 and shall conform to the requirements specified in ASTM D 1784 for a PVC 12454 compound. 2.3.2 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. 2.3.3 Grates. The grates must be aligned properly and fastened by accompanying screws, unless floor sink design is for loose set installation. 2.3.4 Screws. All screws shall be made ofcorrosion resistant material. 2.3.5 Dimensions. PVC floor sink dimensions shall conform to the socket and spigot dimensions as specified in ASTM D 2665.
