30、ON 1 Scope 1.1 These requirements cover portable and xed electric baseboard heating equipment rated at 600 volts or less, to be employed in ordinary locations in accordance with the National Electrical Code, ANSI/NFPA 70. 1.2 Baseboard heating equipment includes baseboard heaters and baseboard heate
31、r accessories. 1.3 Electric baseboard heating equipment intended for use in a hazardous location is judged on the basis of compliance with the requirements in this standard, together with those recognized requirements applicable to usage in hazardous locations. 1.4 Any air heating appliance sold or
32、recommended for use as a baseboard heater, irrespective of its dimensions or other characteristics, is to be identied as a baseboard heater. It will be categorized as a xed or portable baseboard heater in accordance with the following: a) Fixed A heater is identied as a xed baseboard heater if: 1) T
33、he heater is less than 6 in (150 mm) in overall depth, the ratio of the overall length to the overall height is more than two to one, and the heater can be installed completely within a space of 18 in (460 mm) above the oor; or 2) The heater enclosure is intended to be connected to other heater encl
34、osures to form a system. Exception: A heater intended for ceiling mounting or suspended mounting or marked Do Not Install Less Than 6 Feet From Floor is not considered to be a baseboard heater even if it meets the specications in (1) or (2) above. b) Portable A portable heater is identied as a baseb
35、oard heater if, excluding projections of guard or feet, it is less than 5 in (130 mm) in depth and if the ratio of its overall length to its height without the handle is as follows: AUGUST 31, 2009 ELECTRIC BASEBOARD HEATING EQUIPMENT - UL 1042 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REP
36、RODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Maximum height of heater, feet (mm) Ratio of length to height 2 (610) More than 2 to 1 Over 2 (610) More than 3 to 1 Exception: A portable radiant heater which has a visible glowing heating element and which is not sold or recommended for use as a
37、 baseboard heater may be excluded as a baseboard heater even if it meets the dimensional specications in (b) above. Such a heater may be judged under the requirements for movable air heaters in the Standard for Movable and Wall- or Ceiling-Hung Electric Room Heaters, UL 1278. For this determination,
38、 a radiant heater is one in which the visible portion of the heating element attains a temperature of at least 650C (1200F) under normal conditions of operation. 2 Units of Measurement 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate inf
39、ormation. 2A Glossary 2A added January 28, 2013 2A.1 For the purposes of this standard the following denitions apply. 2A.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 a
40、ttachment plug). 2A.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. 2A.4 APPLIANCE (FLATIRON) PLUG An appliance coupler type of device having a c
41、ord guard and a slot conguration specied for use with heating or cooking appliances. 2A.5 COMPONENT 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. lu
42、minaire) is considered to be a component. Unless otherwise specied, materials that compose a device or fabricated part, such as thermoplastic or copper, are not considered components. 2A.6 CONTROL CIRCUIT A circuit that carries the electric signals directing the operation of a controller which, in t
43、urn, governs power delivered to a motor or other load. A control circuit does not carry the main power current. 2A.7 CORD CONNECTOR A female contact device wired on exible cord for use as an extension from an outlet to make a detachable electrical connection to an attachment plug or, as an appliance
44、 coupler, to an equipment inlet. 2A.8 TEMPERATURE CONTROLS Devices that respond with a change in temperature (thermostatic devices) may be one of the following types: a) Regulating Functions only to regulate the temperature of the heater under intended conditions of use, and whose malfunction would
45、not result in a risk of re. JANUARY 28, 2013 ELECTRIC BASEBOARD HEATING EQUIPMENT - UL 1042 6AUL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL b) Limiting Functions only under conditions that produce abnormal temperatures. The malfunction of
46、such a device will result in a risk of re. c) Auxiliary Thermostatic device other than of the regulating or limiting type. d) Operating Control A control intended to start or regulate the heater during normal operation. An example would be a temperature-regulating control. An operating control could
47、 provide Type 1 or Type 2 action. (See denitions 2A.9 2A.12). e) Protective Control A control intended to reduce the risk of electric shock, re, or injury to persons during abnormal operation of the heater. An example would be a temperature limiting control. A protective control always provides Type
48、 2 action. (See denitions 2A.9 2A.12). 2A.9 TYPE 1 ACTION Automatic action for which the manufacturing deviation and the drift of its operating value, operating time, or operating sequence have not been declared and tested to the Standard for Automatic Electrical Controls for Household and Similar U
49、se, Part 1: General Requirements, UL 60730-1A. 2A.10 TYPE 2 ACTION Automatic action for which the manufacturing deviation and the drift of its operating value, operating time, or operating sequence have been declared and tested to the Standard for Automatic Electrical Controls for Household and Similar Use, Part 1: General Requirements, UL 60730-1A. 2A.11 TYPE 2.H ACTION So designed that the contacts cannot be prevented from opening and which may automatic
