35、E AND HEALTH CARE APPLIANCES - UL 1431 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover household electric products having personal hygienics or health care applications, such as hydromassage

36、 units, contact lens disinfectors and cleaners, and toothbrushes, rated at 250 V or less, for use on premises wiring systems in accordance with the National Electrical Code. 1.2 These requirements do not cover professional medical and dental equipment, electrically heated pads, facial saunas, sun an

37、d heat lamps, permanently-installed whirlpool baths, spas and hot tubs, shavers, hair dryers, steam and dry heat cabinets or other equipment or products that are covered by separate, individual requirements separate from this Standard. 1.3 The requirements of this Standard do not consider the comple

38、te spectrum of physiological or therapeutic effects, benecial or otherwise, except where generally recognized limits for conditions where a potential risk of injury to persons are dened. 2 Glossary 2.1 For the purpose of this Standard, the following denitions apply. 2.2 ACCESSIBLE PART A part locate

39、d so that it can be contacted by a person, either directly or by means of a probe or tool during user servicing, or that is not recessed the required distance behind an opening. 2.3 APPLIANCE COUPLER A single-outlet, female contact device for attachment to a exible cord as part of a detachable power

40、-supply cord to be connected to an appliance inlet (motor attachment plug). 2.4 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 appliance coupler or cord connector. 2.5 APPLIANCE (FLAT

41、IRON) PLUG An appliance coupler type of device having a cord guard and a slot conguration specied for use with heating or cooking appliances. 2.6 BASIC INSULATION The insulation applied to live parts to provide basic protection against electric shock. Basic insulation does not necessarily include in

42、sulation used exclusively for functional purposes. 2.7 COMPONENT A device or fabricated part of the appliance covered by the scope of a safety standard dedicated to the purpose. When incorporated in an appliance, equipment otherwise typically eld installed (e.g. luminaire) is considered to be a comp

43、onent. Unless otherwise specied, materials that compose a device or fabricated part, such as thermoplastic or copper, are not considered components. 2.8 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

44、 attachment plug or, as an appliance coupler, to an equipment inlet. 2.9 CONTROL, AUTOMATIC ACTION An appliance coupler type of device having a cord guard and a slot conguration specied for use with heating or cooking appliances.

45、UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 2.10 CONTROL, AUXILIARY A device or assembly of devices that provides a functional utility, is not relied upon as an operational or protective control, and therefore is not relied upon for safe

46、ty. For example, an efficiency control not relied upon to reduce the risk of electric shock, re, or injury to persons during normal or abnormal operation of the end product is considered an auxiliary control. 2.11 CONTROL, MANUAL A device that requires direct human interaction to activate or rest th

47、e control. 2.12 CONTROL, OPERATING A device or assembly of devices, the operation of which starts or regulates the end product during normal operation. For example, a thermostat, the failure of which a thermal cutout/limiter or another layer of protection would mitigate the potential hazard, is cons

48、idered an operating control. Operating controls are also referred to as “regulating controls”. 2.13 CONTROL, PROTECTIVE A device or assembly of devices, the operation of which is intended to reduce the risk of electric shock, re or injury to persons during normal and reasonably anticipated abnormal

49、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. Protective controls are also referred to as “limiting controls” and “safety controls”. Note During the evaluation of the protective control / circuit, the protective functions are veried under normal and single-fault conditions of the control. 2.14 CONTROL, TYPE 1 ACTION The actuation of an automatic cont
