3 Definitions
For the purposes of this part of IEC 60670, the tollowing definitions apply.
3.1
enclosure
combination of parts, such as boxes, covers. cover-plates, lids, box extensions, accessories. etc.. providing alter assembly and installation as in normal use. an appropriate protection against external influences, and a defined protection against contact with enclosed live parts from any accessible direction (see Annex A)
3.2
box
part of an enclosure provided with means for fixing a cover, cover-plate, accessory, etc., and intended to receive accessories (such as socket-outlets, switches. etc.)
3.3
box extension
part of an enclosure which is intended to extend a box for the purpose of either increasing the internal volume of the box or enclosure or to adjust for mounting the box flush or semi-flush with the finished surface of a wall or the like
3.4
lid, cover or cover-plate
part of an enclosure, not integral with or part of an accessory, which may either retain an accessory in position or enclose it
3.5
raised covet
cover intended for mounting directly onto a box to provide for the attachment of accessories and to increase the internal volume of the enclosure
NOTE Th. c.ntre poilion of di. cover as raised 10 accoirnmodate a specific wall or ceiling thickness and to permit lb. mounting of lb. acc.ssoqi on it. flush edh he surface of lb. wail or ceiling.
3.6
exposed conductive part
conductive part ot electrical equipment, which can be touched and which is not normally live, but which can become live when basic insulation falls
3.7
surface mounting box or enclosure
box or enclosure which is intended for mounting on a surface (see Annex A)
3.8
flush-mounting box or enclosure
box or enclosure which is intended for mounting flush with the surface (see Annex A)
3.9
semi-flush mounting box or enclosure
box or enclosure which Is intended to fit within a mounting surface and partially projects from the mounting surface
3.10
cable gland
device designed to permit the entry of a cable into an enclosure and which provides sealing and retention. It may also piovide other functions such as earthing. bonding. insulation, cable guarding, strain relief or a combination of these
3.11
seal (packing)
material used to fill up the space between the inside ci a gland and the cable passing through, usually compressed by the gland and thereby forming a loint
3.12
gasket
material introduced between mating surfaces of an enclosure which in compression forms a loint
3.13
grommet
component used to support and protect the cable or conduit at the point of entry. Ii may also prevent the ingress of moisture or contaminants (see Figure 1)
3.14
entry membrane
component or an integral part of an enclosure used to protect the cable which may be used to support the cable or conduit at the point of entry
NOTE M enlry men*xene may o p’eveix e Wiega at rIlolsMe owwia,xs and may b p1 ot a gnivne (i.e Fli,e I)
3.15
protecting membrane
component or an integral part of an enclosure that is not intended to be penetrated In normal use and Is intended to provide protection against Ingress of water or solid objects and/or to allow the operation of an accessory (see Figure 1)
3.16
composite material
combination of metal and insulating material.
