3 OUTLETS — TYPES AND CONNECTIONS
3.1 Outlet Types
3.1.1 Bottom Outlet. Threaded, inside caulk, spigot, hubless, or solvent-welded with centerline of outlet vertical. (See Fig. 6.)
3.1.2 Side Outlet. Threaded, hub (outside caulk), spigot, hubless, or solvent-welded with centerline of outlet horizontal. (See Fig. 7.)
3.1.3 Side Outlet With Integral Trap. Threaded, hub (outside caulk), spigot, hubless or solvent-welded with centerline of outlet horizontal, and with P trap integral with drain body sump. (See Fig. 8.)
3.2 Outlet Connections 3.2.1 Threaded. All threaded outlet connections shall be American Standard Taper Pipe Threads for general use (NPT) and shall conform to the minimum dimensions shown in Table 1.
3.2.2 Inside Caulk. All inside caulk outlet connec- tions shall conform to the minimum dimensions shown in Table 2. No obstructions shall be permitted in the caulking areas.
3.2.3 Hub (Outside Caulk). All hub connections shall conform to the minimum dimensions shown in Table 3.
3.2.4 Spigot. All spigot outlet connections shall conform to the beadless dimensions shown in ASTM A 74 or ASTM A 888.
3.2.5 Solvent Cement. All solvent-cemented out- let connections shall be made using appropriate solvent cement and methods of joining. ABS solvent cement joints shall be in accordance with ASTM D 2661 and PVC solvent cement joints shall be in accordance with ASTM D 2665.
3.2.6 O-ring or Gasketed Joints. O-ring or gas- keted joints shall comply with ASTM C 564, ASTM C 1440, or CSA B602.
3.3 Tolerances
Dimensions given in Tables 1, 2, and 3 and the associated figures shall be subject to standard commer cial tolerances of ± 1 ⁄16 in. (± 1.6 mm).
4 TOP DIMENSIONS — GRATE-FREE AREA
4.1 Geometry for the Drain Top
The drain top shall be any geometric shape.
4.2 Open Area Requirements for Various Classifications of Drains Opening area requirements for drains shall be as shown in Table
4. 4.3 Openings in Top Grates Openings shall be any geometric shape. Openings shall be sized to exclude debris and accommodate the anticipated traffic. When drainage requirements dictate openings that would permit entrance of debris, a sedi- ment bucket shall be installed in the drain body sump to intercept this debris. 5 TOP LOADING — CLASSIFICATION
5.1 Loading Classifications Grates and top rims shall be designed to meet the following loading classifications:
5.1.1 Light Duty. Grates having safe live load (as calculated in para. 5.2.5) under 2,000 lb (900 kg).
5.1.2 Medium Duty. Grates having safe live load (as calculated in para. 5.2.5) between 2,000 lb (900 kg) and 4,999 lb (2 250 kg).ASME A112.6.3 pdf download.ASME A112.6.3-2001 pdf free download
