Standard Specification for Dough Divider and Rounding Machines
ABSTRACT
This specification covers commercial hand operated dough divider machines and semiautomatic and automatic, electrically operated, dough divider and rounding machines with or without interchangeable heads. Dough dividers and dough divider/rounding machines are classified by type, class, size, and styles: Types I, II, III, and IV; Classes I, II, and III; Sizes 1, 2, and 3; and Styles 1, 2, and 3. Operational test and performance test shall be performed to conform with the specified requirements.
SCOPE
1.1 This specification covers commercial hand operated dough divider machines and semiautomatic and automatic, electrically operated, dough divider and rounding machines with or without interchangeable heads.
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 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.
