(Specification)Standard Specification for Noncarbonated Mechanically Refrigerated Beverage Dispenser (Visible Product)
Standard Specification for Noncarbonated Mechanically Refrigerated Beverage Dispenser (Visible Product)
ABSTRACT
This specification covers counter-top model noncarbonated beverage dispensers that are mechanically refrigerated and have rigid, transparent, impact-resistant containers to afford a visual display of the beverage dispensed. The beverage dispensers covered by this specification are intended to circulate, cool, and dispense noncarbonated beverages such as pulpy juices, frozen concentrates, and syrup drinks. The beverage dispensers shall be of the following types, classes, styles, and sizes: Types I and II; Classes A and B; Styles A (sizes 1, 2, 3, and 4), B (sizes 1 and 2), and C (size 1). The beverage dispenser shall consist essentially of a base that contains a complete refrigeration system and supports a rigid, transparent, impact resistant, bowl-type beverage container(s) with cover(s). Performance test, pull-down test, energy consumption test, maximum ambient temperature and high humidity test, bowl impact test, and operation production performance test shall be performed to conform with the specified requirements.
SCOPE
1.1 This specification covers counter-top model noncarbonated beverage dispensers that are mechanically refrigerated and have rigid, transparent, impact-resistant containers to afford a visual display of the beverage dispensed. The beverage dispensers covered by this specification are intended to circulate, cool, and dispense noncarbonated beverages such as pulpy juices, frozen concentrates, and syrup drinks.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The following safety hazard caveat pertains only to the test method portion, Section 11, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
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.
