(Specification)Standard Specification for Dispensers, Powdered Iced Tea
Standard Specification for Dispensers, Powdered Iced Tea
ABSTRACT
This specification covers counter model, self-contained powdered iced tea dispensers. The tea dispensers shall be of two types, each working with a powdered concentrate that is mixed with potable tap water to give a finished drink. Type I is designed to work with pure tea and Type II is designed to dispense a sugared tea. The dispenser shall be an electromechanical device for dispensing either the pure tea or sugared tea powder and mixing it with tap water upon manual actuation of a momentary-on electrical switch. The instant tea and water shall be mixed in a chamber that will rinse clean at the end of the drink. In order to determine the performance of the dispensers, the following tests shall be performed: energy consumption test, water flow test, ingredient throw test, and humidity test. All components and assemblies of the dispenser shall be free from dirt and other extraneous material such as burrs, slivers, rough die, tool and grind marks, dents, and cracks. Castings and molded parts, if used, shall be free of sand, fins, pits, blowholes, and sprues.
SCOPE
1.1 This specification covers counter model, self-contained powdered iced tea dispensers.
1.2 The dispenser delivered under this specification shall be the manufacturer's standard product. Each dispenser model furnished by a particular manufacturer under this specification, including parts and assemblies thereof, shall be new and interchangeable.
1.3 The values stated in inch-pound units are to be regarded as the standard. The SI units in parentheses are given for information only.
1.4 The following safety hazards caveat pertains only to the test methods 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.
1.5 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.
