This British Standard specifies requirements for ceiling roses having maximum ratings of 6 A and 250 V intended for use in final circuits rated at 16 A maximum for ceiling roses with screw-type supply terminals or 10 A maximum for ceiling roses with screwless supply terminals.
The requirements specified in this standard have particular reference to safety in use.
The ceiling roses are intended for use with cables complying with BS 6004 or BS 6007 having copper conductors and for use with flexible cords complying with BS 6500.
Ceiling roses incorporating means other than rewirable terminals, to facilitate the connection and disconnection of lampholders or luminaires, are not covered by this standard.
NOTE 1 Accessories complying with this standard may be regarded as lighting outlets.
