NOTE See also NOTE to definItion 3,10,
3.13
enclosure
part providing protection of equipment against certain external influences and, in any d.rechon, protoclion against direct contact (1EV 826-03-12]
NOTE The delinilion taken from the exIsting 1EV needs the following explanations under the scope of this standard Ieee IEC 60529. 3.11:
a) enclosures provide ploteclion of persons or livestock against access to hazardous paris:
b) barriers, shapqd openings, or any other means suitabl, to prevent or limit the penetration of the specified test probes. whethec attached to the enclosure or formed by the enclosed equipment. are considered as pan 01 the enclosure, except where they can be removed without the usa of a key or tool.
An enclosure may be
— S Cabinet or bos. either mounted on the machine or separate from th, machine:
— a compartment consisting of an enclosed space within the machine structure.
