31、D SERVING APPLIANCES - UL 1026 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover household electric cooking and food serving appliances, rated at 250 V or less, other than those mentioned in 1
32、.2, for use in ordinary locations, including appliances intended for casual and permanent outdoor use, in accordance with the National Electrical Code, NFPA 70. 1.2 These requirements do not cover household electric ranges, electrode type appliances, skillets and frying type appliances, fondues, wok
33、s, tempuras, corn poppers, coffee makers and brewing type appliances, commercial cooking appliances, microwave cooking appliances, or appliances that are covered in individual requirements that are separate from this Standard. 1.3 For the purposes of this Standard, a requirement that applies to one
34、type of equipment is identied by a specic reference to the type of equipment involved (for example, toaster, rotisserie, or other specic appliance). In the absence of such specic reference or if the term appliance is employed, it is to be understood that the requirement applies to all types of equip
35、ment covered by the Standard. 1.4 These requirements do not cover slow cookers intended for outdoor use. 2 Units of Measurement 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 3 Undated References 3.1 Any undated reference
36、to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 4 Glossary 4.1 For the purpose of this Standard the following denitions apply. 4.2 APPLIANCE COUPLER A single-outlet, female contact device for attac
37、hment to a exible cord as part of a detachable power-supply cord to be connected to an appliance inlet (motor attachment plug). 4.3 APPLIANCE INLET (Motor Attachment Plug) A male contact device mounted on an end product appliance to provide an integral blade conguration for the connection of an appl
38、iance coupler or cord connector. 4.4 APPLIANCE (FLATIRON) PLUG An appliance coupler type of device having a cord guard and a slot conguration specied for use with heating or cooking appliances. 4.5 COMPONENT A device or fabricated part of the appliance covered by the scope of a safety standard dedic
39、ated to the purpose. When incorporated in an appliance, equipment otherwise typically eld installed (e.g. luminaire) is considered to be a component. Unless otherwise specied, materials that compose a device or fabricated part, such as thermoplastic or copper, are not considered components. 4.6 CONT
40、ROL, AUTOMATIC ACTION A control in which at least one aspect is non-manual. AUGUST 1, 2016 ELECTRIC HOUSEHOLD COOKING AND FOOD SERVING APPLIANCES - UL 1026 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4.7 CONTROL, AUXILIARY A device or a
41、ssembly of devices that provides a functional utility, is not relied upon as an operational or protective control, and therefore is not relied upon for safety. For example, an efficiency control not relied upon to reduce the risk of electric shock, re, or injury to persons during normal or abnormal
42、operation of the end product is considered an auxiliary control. 4.8 CONTROL, MANUAL A device that requires direct human interaction to activate or rest the control. 4.9 CONTROL, OPERATING A device or assembly of devices, the operation of which starts or regulates the end product during normal opera
43、tion. For example, a thermostat, the failure of which a thermal cutout/limiter or another layer of protection would reduce the risk of electric shock, re, or injury to persons, is considered an operating control. 4.10 CONTROL, PROTECTIVE A device or assembly of devices, the operation of which is int
44、ended to reduce the risk of electric shock, re or injury to persons during normal and reasonably anticipated abnormal operation of the appliance. For example, a thermal cutout/limiter, or any other control/circuit relied upon for normal and abnormal conditions, is considered a protective control. (D
45、uring the testing of the protective control/circuit, the protective functions are veried under normal and single-fault conditions of the control.) 4.11 CONTROL, TYPE 1 ACTION The actuation of an automatic control for which the manufacturing deviation and the drift (tolerance before and after certain
46、 conditions) of its operating value, operating time, or operating sequence has not been declared and tested under this Standard. 4.12 CONTROL, TYPE 2 ACTION The actuation of an automatic control for which the manufacturing deviation and the drift (tolerance before and after certain conditions) of it
47、s operating value, operating time, or operating sequence have been declared and tested under this Standard. 4.13 CORD CONNECTOR A female contact device wired on exible cord for use as an extension from an outlet to make a detachable electrical connection to an attachment plug or, as an appliance cou
48、pler, to an equipment inlet. 4.14 INDUCTION HEATING APPLIANCES Appliances that can heat at least one metallic vessel by means of eddy currents. The eddy currents are induced to the cooking vessel by the electromagnetic eld of a coil. 4.15 INDUCTION HEATING SYSTEM The inductor current waveform is cre
49、ated by a high-efficiency switched DC power supply and 1-2 IGBT switches. The analog to dialogue switches are driven by a microcontroller, which responds to a feedback loop that forces conditions, such as size/shape/material of cooking vessel, current, voltage or temperature, monitored by sensors to correspond to settings established by the user. 4.16 Deleted. 4.17 INDUCTION TABLE STOVE (HOTPLATE) Table Stove that can heat at least one metallic vessel by means of e
