Standard Specification for Commercial Food Waste Disposers

ABSTRACT
This specification covers commercial food waste disposers intended for the grinding of food waste. Commercial disposers shall be of two types, namely: Type and Type II. The materials shall conform to the specified requirements and include the following: corrosion resistant steel, aluminum alloy, abrasion-resistant cast iron, austenitic gray iron, copper tube, brass pipe, alloy steel, black and galvanized pipe, and gaskets and seals. The disposer construction requirements including requirements for the following are detailed: (1) valves and fittings, (2) hopper (upper housing), (3) grind chamber (lower housing), (4) shredded ring, (5) flywheel, (6) cutting teeth, (7) water seal, (8) bearings, (9) motor, (10) wiring and circuit protective devices, (11) support leg(s), and (12) plating, coating, and painting. Leakage and operations test shall be performed.
SCOPE
1.1 This specification covers commercial food waste disposers intended for the grinding of food waste.  
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 hazards caveat pertains only to the test method portion, Section 9, 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.
