30、machines to be used in accordance withthe National Electrical Code, NFPA 70. This product category includes the following: a floor polisher, floorscrubber, floor sander, floor scraper, tile remover, rug shampooer, rug and floor washer, and a similarmachine for commercial use. A machine such as a san
31、der and wet scrubber with vacuum attachments isalso covered.1.2 These requirements do not cover vacuum cleaning machines, permanently connected machines, orcord-connected machines that are intended to be fastened in place or located in a dedicated space. Theserequirements do not cover machines rated
32、 more than 600 volts, nor do they cover machines involvinguniversal motors rated more than 250 volts. These requirements do not cover floor finishing machines forhousehold use, which are covered in the Standard for Vacuum Cleaners, Blower Cleaners, andHousehold Floor Finishing Machines, UL 1017/ CSA
33、-C22.2 No. 243.1.3 A machine that uses some other source of energy (such as gas or steam) in addition to electricalenergy will be investigated under these requirements and under such additional requirements asapplicable to the machine under consideration.2 General2.1 Terminology2.1.1 In the followin
34、g text, a requirement that applies to one type of equipment (polisher, scrubber, or thelike) is identified by a specific reference in that requirement to the type of equipment involved. In theabsence of such specific reference, or if the term product or machine is used, it is understood that therequ
35、irement applies to all types of equipment covered by the standard.2.2 Units of measurement2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information.2.2.2 Unless indicated otherwise, all voltage and current values mentioned in this st

37、standard shallbe interpreted as referring to the latest edition of that code or standard.3 Glossary3.1 For the purpose of this standard, the following definitions apply.3.2 APPLIANCE COUPLER A single-outlet, female contact device for attachment to a flexible cordas part of a detachable power-supply
38、cord to be connected to an appliance inlet (motor attachmentplug).3.3 APPLIANCE INLET (MOTOR ATTACHMENT PLUG) A male contact device mounted on an endproduct appliance to provide an integral blade configuration for the connection of an appliance coupleror cord connector.3.4 COMMERCIAL USE PRODUCT A p
39、roduct not intended for use only in the home.3.5 COMPONENT A device or fabricated part of the appliance covered by the scope of a safetystandard dedicated to the purpose. When incorporated in an appliance, equipment otherwise typicallyfield installed (e.g. luminaire) is considered to be a component.
40、 Unless otherwise specified, materialsthat compose a device or fabricated part, such as thermoplastic or copper, are not consideredcomponents.3.6 CONTROL, AUTOMATIC ACTION A control in which at least one aspect is non-manual.3.7 CONTROL, AUXILIARY A device or assembly of devices that provides a func
41、tional utility, is notrelied upon as an operational or protective control, and therefore is not relied upon for safety. Forexample, an efficiency control not relied upon to reduce the risk of electric shock, fire, or injury topersons during normal or abnormal operation of the end product is consider
42、ed an auxiliary control.3.8 CONTROL, MANUAL A device that requires direct human interaction to activate or rest thecontrol.3.9 CONTROL, OPERATING A device or assembly of devices, the operation of which starts orregulates the end product during normal operation. For example, a thermostat, the failure
43、 of which athermal cutout/limiter or another layer of protection would reduce the risk of electric shock, fire, or injuryto persons, is considered an operating control.3.10 CONTROL, PROTECTIVE A device or assembly of devices, the operation of which is intendedto reduce the risk of electric shock, fi
44、re or injury to persons during normal and reasonably anticipatedabnormal operation of the appliance. For example, a thermal cutout/limiter, or any other control/circuitrelied upon for normal and abnormal conditions, is considered a protective control.Note During the evaluation of the protective cont
45、rol/circuit, the protective functions are verified undernormal and single-fault conditions of the control.3.11 CONTROL, TYPE 1 ACTION The actuation of an automatic control for which the manufacturingdeviation and the drift (tolerance before and after certain conditions) of its operating value, opera

47、ntrol for which the manufacturingdeviation and the drift (tolerance before and after certain conditions) of its operating value, operatingtime, or operating sequence have been declared and tested under this standard.3.13 HAND-GUIDED PRODUCT A portable product which during intended use is contacted b
48、y thehand of the user for purposes of electrical or physical control, but not for complete support.3.14 HAND-SUPPORTED PRODUCT A portable product that is completely supported by the userduring the performance of its intended function. The hand of the user may also be used to exerciseelectrical or ph
49、ysical control of the operation of the product.3.15 LINE-VOLTAGE CIRCUIT A circuit involving a potential of not more than 600 volts and havingcircuit characteristics in excess of those of a low-voltage circuit.3.16 LOW-VOLTAGE CIRCUIT A circuit involving a peak open-circuit potential of not more than 42.4volts supplied by a primary battery, by a Class 2 transformer, or by a combination of a transformer anda fixed impedance that, as a unit, complies with all performance requirements for a Class 2 transform
