3 Definitions
For the purpose of this standard, the following definitions apply: 3.1 enclosure a part providing protection of equipment against certain external influences and, in any direction, protection against direct contact [IEV 826-03-12] * . NOTE This definition taken from the existing International Electrotechnical Vocabulary (IEV) needs the following explanations under the scope of this standard: 1) Enclosures provide protection of persons or livestock against access to hazardous parts. 2) Barriers, shapes of openings or any other means – whether attached to the enclosure or formed by the enclosed equipment – suitable to prevent or limit the penetration of the specified test probes are considered as a part of the enclosure, except when they can be removed without the use of a key or tool. 3.2 direct contact contact of persons or livestock with live parts [IEV 826-03-05] 3.3 degree of protection the extent of protection provided by an enclosure against access to hazardous parts, against. ingress of solid foreign objects and/or against ingress of water and verified by standardized test methods 3.4 IP Code a coding system to indicate the degrees of protection provided by an enclosure against access to hazardous parts, ingress of solid foreign objects, ingress of water and to give additional information in connection with such protection 3.5 hazardous part a part that is hazardous to approach or touch 3.5.1 hazardous live part a live part which, under certain conditions of external influences, can give an electric shock (see IEC 60050-195, 195-06-05) 3.5.2 hazardous mechanical part a moving part, other than a smooth rotating shaft, that is hazardous to touch 3.6 protection provided by an enclosure against access to hazardous parts the protection of persons against – contact with hazardous low-voltage live parts – contact with hazardous mechanical parts – approach to hazardous high-voltage live parts below adequate clearance inside an enclosure NOTE This protection may be provided – by means of the enclosure itself, – by means of barriers as part of the enclosure or distances inside the enclosure.3.7 adequate clearance for protection against access to hazardous parts a distance to prevent contact or approach of an access probe to a hazardous part 3.8 access probe a test probe simulating in a conventional manner a part of a person or a tool, or the like, held by a person to verify adequate clearance from hazardous parts 3.9 object probe a test probe simulating a solid foreign object to verify the possibility of ingress into an enclosure 3.10 opening a gap or aperture in an enclosure which exists or may be formed by the application of a test probe at the specified force.
