Sieve, Sieve Frame: The sieve frame shall be of metal, not subject to corrosion by water. And, shall be circular, either 51 ± 6mm, 2.0 ± 0.25 in. When woven-wire cloth is mounted in the frame, or 76 ± 6 mm, 3.0 ± 0.25 inches in diameter. When an electro-formed sheet is mounted in the frame, the depth of the sieve, from the top of the frame to the cloth or sheet, shall be 76 ± 6mm, 3.0 ± 0.25 in. The frame shall have, either side walls of 89 ± 6mm, 3.5 ± 0.25 inches in total height. Or legs, at least 12mm, 0.5 inches in length, sufficient to allow air circulation beneath the sieve cloth or electro-formed sheet. Spray Nozzle: The spray nozzle, figure 1, shall be constructed of metal, not subject to corrosion by water. And shall be 17.5 mm, 0.69 inches in inside diameter, with central hole drilled in line with the longitudinal axis, in an intermediate row of 8 holes, drilled 6 mm, 0.23 inches center to center, at an angle of 5 degrees from the longitudinal axis. And an outer row of 8 holes drilled of 11 mm, 0.44 inches center to center, at an angle of 10 degrees from the longitudinal axis. All hole shall be 0.5 mm, 0.02 inches in diameter. The spray nozzle shall have been checked within 6 months prior to testing a cement sample, to ensure that the flow rate is between 1500 and 3000 grams per minute, at 69 ± 3 kPa, 10 ± 0.4 psi.
