A minimum of three bolts per drain shall be provided. Screw and bolts provided lor shower drains shall be 300 series stainless steel or copper alloy complying with ASTM B 5)1.4 (Alloy C X52(i0 or C 85400) or ASThI B 16.
3 OUTLETS — TYPES AND CONNECTIONS
3.1 Outlet Types
3.1.1 Bottom Outlet. Threaded, inside caulk. spigot. hublcss. or solvent-welded with centerline of outlet vertical. (See Fig. 6.)
3.1.2 Side Outlet. Threaded, huh (outside caulk). spigot. hubless. or solvent-welded with centerline of outlet horizontal. (Sec Fig. 7.)
5.1.4 Extra Heavy Duty. Grates having safe liveload (as calculated in para.5.2.5) between 7.500 lb(3 375 kg) and 10,000 ib (4 500 kg)
5.1 .5 Special Duty. Grates having safe live loadas calculated in para. 5.2.5) over 10.0O0 lb (4 500 kg)shall be considered special duty.
5.2 Test Procedure for Grate Loading
Safe live load requirements，as listed in para. 5.1shall be determined as follows:
5.2.1 Load Classifications. Load classificationsas stated in para. 5.1 shall be determined by labora-tory tests.
5.2.2 Platen Size. A 3.5 in. (89 mm) diameterplaten shall be applied to the center of the gratespecimen.
5.2.3 Loading. Loading shall be applied slowly sothat point of failure can be observed.
5.2.4 Point of Failure
(a) Britrle Materials (Casr Iron ).The point of failureof brittle materials shall be the load (in pounds orkilograms) at which the first fracture on any part ofthe specimen appcars.
byDucrile Material. The point of failure of ductilematerials shall be the load at which the permanent sctat the point of loading) is greater than2% of thelongest transverse dimcnsion of the specimen.
5.2.5 Safe Live Load. The maximum safe liveload shall be computed by dividing the load at failureby two.
6 MATERIALS AND FINISHES6.1 Materials
The items covered in this Standard shall be ofthe material specified and shall meet all applicablerequirements and standards given herein. The castingsfor these drains shall be sound, free of blow holes,cold shuts,and other imperfections, and shall be ofuniform wall thickness and true to pattern.They shallalso be clean and free of fins. It shall not be the intentof this Standard to limit acceptable materials to those included in this section.
