27、nd therefore is not relied upon for safety. Forexample, an efficiency control not relied upon to reduce the risk of fire, electric shock, or injury to personsduring normal or abnormal operation of the end product is considered an auxiliary control.4.3 CONTROL, OPERATING A device or assembly of devic
28、es, the operation of which starts orregulates the end product during normal operation. For example, a thermostat, the failure of which athermal cutout/limiter or another layer of protection would mitigate the risk of fire, electric shock, or injuryto persons, is considered an operating control.4.4 C
29、ONTROL, PROTECTIVE A device or assembly of devices, the operation of which is intended toreduce the risk of fire, electric shock, or injury to persons during normal and reasonably anticipatedabnormal operation of the appliance whereby during the evaluation of the protective control/circuit, theprote
30、ctive functions are verified under normal and single-fault conditions of the control. For example, athermal cutout/limiter, or any other control/circuit relied upon for normal and abnormal conditions, isconsidered a protective control.4.5 ELECTRICAL ENCLOSURE A part of the equipment intended to redu
31、ce the risk of contact withelectrical circuits.4.6 MECHANICAL ENCLOSURE A part of the equipment intended to reduce the risk of injury due tomechanical and other physical hazards.4.7 NORMAL LOAD Operation with drive wheels engaged, an operator with a minimum weight of 91 kg(200 lb) seated on the mach
32、ine during the test, and with the deck adjusted in the highest cutting position.The test surface shall be a substantially level (not to exceed 1% grade), dry, smooth, hard-surfaced areaof concrete, asphalt (or other surface with equivalent coefficient of surface friction), that is free from loosemat

36、h its rating established for the intended conditions of use;c) Be used within its established use limitations or conditions of acceptability; andd) Additionally comply with the applicable requirements of this Outline of Investigation.5.1.3 A component of a product covered by this Outline of Investig
37、ation is not required to comply with aspecific component requirement that:a) Involves a feature or characteristic not required in the application of the component in theproduct;b) Is superseded by a requirement in this Outline of Investigation; orc) Is separately investigated when forming part of an
38、other component, provided the componentis used within its established ratings and limitations.5.1.4 A component that complies with a UL component standard other than those specified in 5.2 5.13is acceptable if:a) The component also complies with the applicable component standard specified in 5.2 5.1
39、3; orb) The component standard:1) Is compatible with the ampacity and overcurrent protection requirements in NationalElectrical Code, NFPA 70, where appropriate;2) Considers long-term thermal properties of polymeric insulating materials inaccordance with UL 746B; and3) Any use limitations of the oth
40、er component UL standard is identified andappropriately accommodated in the end use application. For example, a componentused in a household application, but intended for industrial use and complying with therelevant component standard may assume user expertise not common in householdapplications.FE
