ASME A112.14.3:2018 pdf download.Hydromechanical Grease Interceptors.

(b) For flow rates upto and IncludIng 50 gpm (189 LI mm) the test sinks shall be 50 gal (189 1) and have the

following Inside dimensions: 8 ft (2.44 m) in length, 2 ft (0.61 m) in width, and 12 in, (0.32 m) in depth.

The sinks shall have two compartnwnts of equal length.

(c) For (low rates above 50 gpm (189 L/min) up to and including 100 gpm (378 L/min). the test sinks shall be as

follows:

(1) multiples of two of the sinks specified in (b).

(2,) a 100 gal sink having the following dimensions:

128 in. (3.2 m) in length, 36 in. (0.91 m) in width, and 12.5 In. (0.32 m) in depth; it shall be divided into two equal compartments.

(d) For flow rates ofgreater than 100 gpm (378 1./mm). two or more sinks as specified in (b) or (c) shall be used.

3.1.1.1 Sink Waste Connections. For sinks constructed per para. 3.1.1(b), each sink compartment shall be fitted

with a 1/2 in. (38 mm) standard sink waste connection with flange, threaded or slip joint tall- piece, and

locknut. The waste connections shall be located on opposite sides of the center partition in the corner formed by the front side of the sink and the center partition.

For sinks constructed per para. 3.1.1(c). each sink compartment shall be fitted with a 2 in. (51 mm) sink waste

connection with flange, threaded or slip joint tail- piece, and locknut. The w.cte connections shall he located on opposite sides of the center partition in the corner formed by the front side of the sink and the center

partition.

3.112 Water Level Gauges. Each compartment shall be equipped with a gauge connection and a waler level gauge with gauge glass. Each gauge connection shall be fitted into the bottom of a sink compartment and in close proximity

to the waste outlet. Each gauge shall be mounted on the outside of the sink, ad(acent to its respective gauge connection, and shall extend diagonauy upward from the bottom center to the top outside corners. These gauges shall be calibrated to read the number of inches of water In the sink compartments above the sink waste flange.

3.1.1.3 Movable Sink Partitions. Each compartment othe sink shall be titted with a movable partition, making it

possible to regulate the size of the compartment to any desired capacity.
