Standard Specification for Induction Cooktops, Counter Top, Drop-in Mounted, or Floor Standing

ABSTRACT
This specification covers design and construction, physical properties, and performance requirements for cooktops which utilize induction as a means for cooking and warming food in commercial and institutional food service establishments. Included are tabletop units, drop-in units and floor standing equipment with integral induction hobs. Testing methods include temperature control accuracy test, dry pan test, minimum load detection test, operating power test, and induction cooktop efficiency test.
SCOPE
1.1 This specification covers cooktops which utilize induction as a means for cooking and warming food in commercial and institutional food service establishments. Included are tabletop units, drop-in units and floor standing equipment with integral induction hobs.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The SI values given in parentheses are provided for information only.  
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.
