27、 REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover motor operated household and commercial disposers rated 600 V or less and intended to be used in accordance with the National Electrical Code, ANSI/NFPA 70. These disposers are intended to conv
28、ert organic types of waste material to a form that can be accommodated by plumbing systems. The requirements also cover eld-installed control assemblies and accessories specically intended for use with disposers covered by this standard. 1.2 These requirements do not cover an incinerator-type dispos
29、er or a disposer using a universal motor with a rating greater than 250 V. 2 Units of Measurement 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 3 Undated References 3.1 Any undated reference to a code or standard appearin
30、g in the requirements of this standard shall be 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 BARRIER A part of a disposer that functions to reduce the risk of access to current-carrying par
31、ts or internal wiring through openings in the enclosure that involves a risk of electric shock or injury to persons, or reduces the risk of re or injury to persons as a result of molten metal or burning insulation being expelled through openings in the enclosure under abnormal conditions. 4.3 COMPON
32、ENT 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 component. Unless otherwise specied, materials that compose a dev
33、ice or fabricated part, such as thermoplastic or copper, are not considered components. 4.4 CONTROL, AUTOMATIC ACTION A control in which at least one aspect is non-manual. 4.5 CONTROL, AUXILIARY A device or assembly of devices that provides a functional utility, is not relied upon as an operational
34、or protective control, and therefore is not relied upon for safety. For example, an efficiency control not relied upon to reduce the risk of re, electric shock, or injury to persons during normal or abnormal operation of the end product is considered an auxiliary control. 4.6 CONTROL, MANUAL A devic
35、e that requires direct human interaction to activate or rest the control. SEPTEMBER 8, 2015 WASTE DISPOSERS - UL 430 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4.7 CONTROL, OPERATING A device or assembly of devices, the operation of wh
36、ich 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 risk of re, electric shock, or injury to persons, is considered an operating control. 4.8 CONTROL, PROTECTIVE A
37、device or assembly of devices, the operation of which is intended to reduce the risk of re, electric shock, or injury to persons during normal and reasonably anticipated abnormal operation of the appliance whereby during the evaluation of the protective control/circuit, the protective functions are
38、veried under normal and single-fault conditions of the control. For example, a thermal cutout/limiter, or any other control/circuit relied upon for normal and abnormal conditions, is considered a protective control. 4.9 CONTROL, TYPE 1 ACTION The actuation of an automatic control for which the manuf
39、acturing deviation and the drift (tolerance before and after certain conditions) of its operating value, operating time, or operating sequence has not been declared and tested under this end product standard. 4.10 CONTROL, TYPE 2 ACTION The actuation of an automatic control for which the manufacturi
40、ng deviation and the drift (tolerance before and after certain conditions) of its operating value, operating time, or operating sequence have been declared and tested under this end product standard. 4.11 DECORATIVE PART A part used for no function other than appearance. 4.12 ENCLOSURE That portion
41、of a disposer that: a) Renders inaccessible any part that presents a risk of electric shock or injury to persons; b) Reduces the risk of ame propagation initiated by electrical disturbances occurring within; or c) Both. A grill, guard, panel, barrier, or similar part forms part of an enclosure if it
42、 reduces the risk of contact with an uninsulated current-carrying part or a part that presents a risk of injury to persons. 4.13 FUNCTIONAL PART A part that is necessary for the intended operation of the disposer, the deterioration of which may result in a risk of re, electric shock, or injury to pe
43、rsons. 4.14 HOPPER A container that funnels material into the disposer prior to the reduction process.

44、component of a product covered by this standard shall: a) Comply with the requirements for that component as indicated in 5.2 5.19; b) Be used in accordance with its rating(s) established for the intended conditions of use; c) Be used within its established use limitations or conditions of acceptabi
45、lity; d) Additionally comply with the applicable requirements of this end product standard; and e) Not contain mercury. Exception No. 1: A component of a product covered by this standard is not required to comply with a specic component requirement that: a) Involves a feature or characteristic not r
46、equired in the application of the component in the product; b) Is superseded by a requirement in this standard; or c) Is separately investigated when forming part of another component, provided the component is used within its established ratings and limitations. Exception No. 2: A component that co
47、mplies with a UL component standard other than those specied in 5.2 5.19 is acceptable if: a) The component also complies with the applicable component standard specied in 5.2 5.19; or b) The component standard: 1) Is compatible with the ampacity and overcurrent protection requirements in the Nation
48、al Electrical Code, ANSI/NFPA 70, where applicable; 2) Considers long-term thermal properties of polymeric insulating materials in accordance with the Standard for Polymeric Materials Long Term Property Evaluations, UL 746B; and 3) Any use limitations of the other component standard are identied and
49、 appropriately accommodated in the end use application. For example, a component used in a household application, but intended for industrial use and complying with the relevant component standard may assume user expertise not common in household applications.
