This specification covers the design, performance, and certification requirements pertinent to the construction of commercial automatic ice making machines used in manufacturing and processing ice, including the attached equipment used in storing and dispensing the produced ice for human consumption. This specification does not apply to icemakers of the tray type, ice vending machines, icemakers and icemaker kits used in household refrigerators or freezers, and block ice manufacturing plants. The ice machines covered here are classified into the following types, grades, classes, and styles: Type I-ice machine with or without ice storage bin; Type II-icemaker-dispenser machine; and Type III-ice dispenser; Grade 1-self-contained air-cooled condenser; Grade 2-self-contained water-cooled condenser; Grade 3-remote water-cooled; and Grade 4-remote air-cooled; Class A-cubed ice; Class B-flaked ice; Class C-nugget ice; and Class D-other ice shapes; Style 1-corrosion-resisting steel cabinet; Style 2-carbon steel cabinet; and Style 3-plastic cabinet. Representative production models of the ice making machines shall pass the performance and operational tests, and should function satisfactorily as specified.
