ASTM F1568-12(2023)

Standard Specification for Food Processors, Electric

ABSTRACT
This specification covers commercial food processors intended for bench, table, or floor mounting. Types: type I - this machine shall have a hopper of the continuous, manual-feed type, and type II - this machine shall have a closed-bowl type of hopper. Classes: class 1 - table- or bench-mounted food processor, and class 2 - floor-mounted food processor. Interlock integrity test, plate stopping time test, type I food processor operation tests, type II food processor operation test, motor performance test, power transmission test, and sound level test shall be performed to meet the requirements prescribed.
SCOPE
1.1 This specification covers commercial food processors intended for bench, table, or floor mounting.  
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 methods 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.
