35、tric personal grooming appliances intended for use by qualied personnel in commercial establishments such as beauty parlors, barber shops, or cosmetic studios. These appliances include hair curlers and dryers, combs, brushes, and similar appliances that are to be employed in accordance with the Nati
36、onal Electrical Code, ANSI/NFPA 70. 1.2 These requirements do not cover therapeutic lamps, diathermy equipment, massage machines, vibrators, hair clippers, shavers, facial caps, masks, mitts, or other appliances covered by other requirements such as in the Standard for Medical Electrical Equipment,
37、Part 1: General Requirements for Safety, UL 60601-1. These requirements also do not cover hair curlers or dryers rated at more than 250 volts. 2 Units of Measurement 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.2 Unles
38、s otherwise indicated, all voltage and current values mentioned in this standard are root-mean-square (rms). 3 Undated References 3.1 Any undated reference 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 sta
39、ndard. 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 attachment to a exible cord as part of a detachable power-supply cord to be connected to an appliance inlet (motor attachment plug). 4.2 added May 21
40、, 2012 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 appliance coupler or cord connector. 4.3 added May 21, 2012 4.4 APPLIANCE (FLATIRON) PLUG An appliance coupler type of device
41、 having a cord guard and a slot conguration specied for use with heating or cooking appliances. 4.4 added May 21, 2012 4.5 AUTOMATIC CONTROL A device intended for automatic control of operating time, temperature, or pressure under conditions of intended operation and not for protection against condi
42、tions resulting from abnormal operations. 4.6 AUTOMATICALLY CONTROLLED APPLIANCE An appliance is considered to be automatically controlled if it complies with one or more of the following conditions: MAY 21, 2012 COMMERCIAL ELECTRIC PERSONAL GROOMING APPLIANCES - UL 1727 7UL COPYRIGHTED MATERIAL NOT
43、 AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL a) The repeated starting of the appliance is independent of any manual control if, after one complete cycle of operation, a limit device or similar device opens the circuit. b) During any single preset cycle of operation
44、, the motor is caused to stop and restart. c) When the appliance is energized, the initial starting of the motor may be intentionally delayed beyond intended, conventional starting. d) For an appliance employing a motor with a separate starting winding, during any single predetermined cycle of opera
45、tion automatic changing of the mechanical load reduces the motor speed sufficiently to re-establish starting-winding connections to the supply circuit. 4.7 BODY-SUPPORTED APPLIANCE An appliance that is physically supported by any part of the body, other than the hand of the user, during the performa
46、nce of its intended electrically operated functions (such as a shoulder-, body-, or head-supported hair dryer) is to be considered a body- supported appliance. Reference is to be made to the user manual of the appliance in establishing the intended electrically operated functions of the appliance. 4
47、.8 CONTINUOUS-DUTY MOTOR A motor that can operate unattended and under load under any normal conditions of use for 3 hours or more. 4.9 CONTROL, AUTOMATIC ACTION A control in which at least one aspect is non-manual. 4.9 added May 21, 2012 4.10 CONTROL, AUXILIARY A device or assembly of devices that
48、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 operation of the end pro
49、duct is considered an auxiliary control. 4.10 added May 21, 2012 4.11 CONTROL, MANUAL A device that requires direct human interaction to activate or reset the control. 4.11 added May 21, 2012 4.12 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 reduce the risk of electric shock, re, or injury to per
