Clinical Engineering Equipment
Class
II
Definition
Class II equipment fused at the equipment end of the supply lead in either mains conductor or in both conductors if the equipment has a functional earth.
Symbol
III
Definition
Class III equipment is defined in some equipment standards as that in which protection against electric shock relies on the fact that no voltages higher than safety extra low voltage (SELV) are present.
I
Definition
Class I equipment have fuses at the equipment end of the mains supply lead in both the live and neutral conductors so that the supplementary protection is operative when the equipment is connected to an incorrectly wired socket outlet.
Symbol
Protective earth
Equipotential
Earth
Type
BF
Definition
As type B but with isolated or floating (F-type) applied part or parts.
Symbol
CF
Definition
Equipment providing a higher degree of protection against electric shock than type BF, particularly with regards to allowable leakage currents and having floating applied parts.
Symbol
B
Symbol
Definition
Equipment providing a particular degree of protection against electric shock, particularly regarding allowable leakage currents and reliability of the protective earth connection.
