BS 6396:2008 pdf free.ELECTRICAL SYSTEMS IN OFFICE FURNITURE AND EDUCATIONAL FURNITURE – SPECIFICATION.
This British Standard BS 6396 specifies requirements for the safe provision and assembly of electrical power, data and telecommunications distribution systems in office furniture, educational furniture and office screens. Requirements are specified for furniture for general use and for furniture for use with specific equipment, parts of which may be built in during manufacture.
Appropriate tests are described for the installed power distribution system in the furniture. The standard applies to single-phase electrical power distribution systems operating at rated voltages up to 250 V a.c. that are connected to the fixed wiring of the permanent installation of the building by a 13 A fused plug and socket outlet arrangement conforming to BS 1363. The standard makes provision for the routing of cables through the furniture.
BS 6396 does not apply to electrical appliances used with or within an article of office furniture or educational furniture, for which appropriate standards are available. The standard does not apply to power distribution systems that are permanently connected to the building installation. The standard also does not apply to special purpose workstations in laboratories or workshops.
3 Terms and definitions
For the purposes of this British Standard, the definitions given in BS 4727-1 apply, together with the following.
3.1 appliance coupler
means of enabling the connection and disconnection at will of a flexible cable or cord to an appliance or other equipment. It consists of two parts:
a) a connector, which is the part integral with, or intended to be attached to, the flexible cable or cord connected to the supply; and
b) an appliance inlet, which is the part integrated in or incorporated in the appliance or equipment, or intended to be fixed to it.
3.2 basic insulation
insulation to provide basic protection against electric shock
3.3 supplementary insulation
independent insulation applied in addition to basic insulation in order to ensure protection against electric shock in the event of a failure of the basic insulation
3.4 double insulation
insulation comprising both basic insulation and supplementary insulation
3.5 reinforced insulation
single insulation system that provides a degree of protection against electric shock equivalent to double insulation under the conditions specified in BS EN 60950
NOTE: The term “insulation system” does not imply that the insulation has to be one homogeneous piece. It may comprise several layers that cannot be tested as supplementary or basic insulation.
