2.2 Epoxy Coating
The visible surface after installation of each floorsink shall be acid-resisting epoxy,thoroughly fused tothe cast iron base. It shall be free from flaws that mayeffect the appearance or serviceability of the floor sink.The epoxy surface shall be examined for blemishes inaccordance with Section 6 of ASME A112.19.1.
2.2.1 Surface Epoxy. The surface epoxy，visibleafter installation,shall be glossy to the extent that itwill have a 1.05 rad. (60 deg.) specular gloss of notless 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 1in. (25 mm) from any edge shall not be less than 4mils (O.1 mm).
2.2.3 Acid Resistance.The epoxy coating shall beacid 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 shallbe made of a single PvC virgin compound exceptas providled in para. 2.3.2 and shall conform to therequirements specified in ASTM D 1784 for a Pvc12454 compound.
2.3.2 Reworked Plastic. Clean，reworked plasticgenerated from the manufacturer’s own PvC 12454products may be used provided the floor sinks producedmeet the requirements of this Standard.
2.3.3 Grates. The grates must be aligned properlyand fastened by accompanying screws, unless floor sinkdesign is for loose set installation.
2.3.4 Screws.All screws shall be made of corrosionresistant material.
2.3.5 Dimensions.PVC floor sink dimensions shallconform to the socket and spigot dimensions as specifiedin ASTM D 2665.

3 FLOOR SInNK TYPES AND SIzES
3.1 lllustrations
The floor sink type and sizes illustrated in Figs. lthrough 4 are commonly cast iron and Figs. 5 through7 are commonly PvC. but other type materials maybe provided. Those illustrated represent a selection forordinary types and may be provided with a variey oftops.Top grates shall meet the requirements of ASMEA112.21.1.
3.2 Floor Sinks Without Anchor Flanges
Floor sinks without anchor flanges are for use whereanchoring or clamping of a waterproof membrane isnot required.
3.3 Floor Sinks With Anchor Flanges
Floor sinks with anchor flanges are for use whereanchoring or clamping of a waterproof membrane isrequired. The membrane is to be secured to the anchorflange with flange clamps. Provisions shall be madein the drain body for weepholes. They shall be castin the cast iron body and drilled in the PvC body ifnecessary (see Figs. 5 through 7).
3.4 Grate Configurations
Grate configurations shall be either full，314,or ‘h2design. See Figs. 8 through 10. Direction of slots mayvary depending on the manufacturer.
4 oUTLET SIZE AND CONNECTION
Outlet size and connections shall be in accordancewith ASME A112.21.1 and/or ASTM A 888. Pvcshall also be in accordance with ASTM D 2665.
5 TESTING
5.1 Enameled Cast lron Floor Sink
Enameled cast iron floor sinks shall be subjected tothe tests outlined in Section 7、ASME A112.19.1，withthe exception of the Lavatory Overflow Test (para.7.5).
