38、milar appliances that are to be employed in accordance with the National 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 req
39、uirements such as in the Standard for Medical Electrical Equipment, 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
40、in parentheses are explanatory or approximate information. 2.2 Unless 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 b
41、e 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 attachment to a exible cord as part of a detachable power-supply cord to be conne
42、cted to an appliance inlet (motor attachment plug). 4.2 added May 21, 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, 20
43、12 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. 4.4 added May 21, 2012 4.5 AUTOMATIC CONTROL A device intended for automatic control of operating time, temperature, or pressure under c
44、onditions of intended operation and not for protection against conditions 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
45、 PERSONAL GROOMING APPLIANCES - UL 1727 7UL COPYRIGHTED MATERIAL NOT 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 devi
46、ce opens the circuit. b) During any single preset cycle of operation, 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 separ
47、ate starting winding, during any single predetermined cycle of operation 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 pa
48、rt of the body, other than the hand of the user, during the performance 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 establish
49、ing the intended electrically operated functions of the appliance. 4.8 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 provides a functional utility, is not relied upon as an operational or protective control, and therefore is not relied upon for saf
