30、e protection from the weather and other outdoor influences such as rain, dust, etc. normally provided by a building or other structure is limited or non-existent. There are many examples of information technology equipment in use throughout the world that are housed in special ENCLOSURES located on
31、pavements, mounted on telecommunications poles and situated underground. Presently, IEC 60950 has no requirements for such equipment and this proposal would rectify this omission. The proposed requirements would not apply to portable or transportable equipment that may be occasionally used outdoors,
32、 but are not intended to be installed in conditions of inclement weather. It is expected that IEC TC108 will continue to coordinate the output of its work with other technical committees dealing with equipment installed outdoors, such as IEC TC70 (Degrees of Protection by Enclosures, responsible for
33、 IEC 60529) and IEC TC48 (Electromechanical Components and Mechanical Structures for Electronic Equipment). Annex E describes the rationale behind the treatment of specific safety aspects in this standard. Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 09 14:53:09 GMT+00:00 2006, Uncontrolled C

The requirements for OUTDOOR EQUIPMENT
35、 also apply, where relevant, to empty OUTDOOR ENCLOSURES supplied for housing information technology equipment to be installed in an OUTDOOR LOCATION. 1.2 Additional requirements Each installation may have particular requirements. Some examples are given in 4.2. In addition, requirements for protect
36、ion of the OUTDOOR EQUIPMENT against the effects of direct lightning strikes are not covered by the standard.

44、r partly to the conditions in an OUTDOOR LOCATION NOTE TRANSPORTABLE EQUIPMENT, for example, a laptop or notebook computer, or a telephone, is not OUTDOOR EQUIPMENT unless specified by the manufacturer for continuous use in an OUTDOOR LOCATION. 3.3 OUTDOOR ENCLOSURE part of OUTDOOR EQUIPMENT that is
45、 exposed to the adverse conditions in an OUTDOOR LOCATION and that is intended to protect the interior of the equipment from those conditions NOTE 1 An OUTDOOR ENCLOSURE can also perform the functions of one or more of the following: a FIRE ENCLOSURE; an ELECTRICAL ENCLOSURE; a MECHANICAL ENCLOSURE.
46、 NOTE 2 A separate cabinet or housing into which the equipment is placed can provide the function of an OUTDOOR ENCLOSURE.

47、temperature OUTDOOR EQUIPMENT and OUTDOOR ENCLOSURES shall be suitable for use at any temperature in the range specified by the manufacturer. If not specified by the manufacturer, the range shall be taken as: minimum ambient temperature; 33 C maximum ambient temperature; +40 C. Compliance is checked
48、 by inspection. NOTE 1 The temperature values are based on IEC 60721-3-4 Class 4K2. These temperatures do not take into account severe environments (for example, extremely cold or extremely warm), nor do they include provision for heating by radiation from the sun (solar loading).
