(Specification)Standard Specification for Ice Making Machines, Icemaker-Dispensers, and Ice Dispensing Equipment
Standard Specification for Ice Making Machines, Icemaker-Dispensers, and Ice Dispensing Equipment
ABSTRACT
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.
SCOPE
1.1 This specification covers requirements for commercial automatic ice making equipment. It covers the equipment and devices used in manufacturing and processing ice for human consumption and the attached equipment used in storing and dispensing ice in connection with this equipment.
1.2 This specification does not apply to icemakers of the tray type, ice vending machines, or icemakers and icemaker kits used in household refrigerators or freezers. This specification is not intended to cover block ice manufacturing plants.
1.3 The values stated in inch-pound units are to be regarded as the standard. The SI values given in parenthesis are provided for information only.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
