EQUIPMENT parts
TYPE B APPLIED
PART APPLIED PART complying with the specified requirements of this
Standard to provide protection against electric shock, particularly
regarding allowable LEAKAGE CURRENT and marked with the symbol
on the left.
NOTE: TYPE B APPLIED PARTS are not suitable for DIRECT
CARDIAC APPLICATION.
TYPE BF APPLIED
PART F-TYPE APPLIED PART complying with the specified requirements of
this Standard to provide a higher degree of protection against electric
shock than that provided by TYPE B APPLIED PARTS and marked
with the symbol on the left.
NOTE: TYPE BF APPLIED PARTS are not suitable for DIRECT
CARDIAC APPLICATION.
TYPE CF APPLIED
PART F-TYPE APPLIED PART complying with the specified requirements of
this Standard to provide a higher degree of protection against electric
shock than that provided by TYPE BF APPLIED PARTS and marked
with the symbol on the left.
F-TYPE ISOLATED
(FLOATING)
APPLIED PART
(hereinafter referred
to as F-TYPE
APPLIED PART) APPLIED PART isolated from other parts of the EQUIPMENT to such
a degree that no current higher than the PATIENT LEAKAGE
CURRENT allowable in SINGLE FAULT CONDITION flows if an
unintended voltage originating from an external source is connected to
the PATIENT, and thereby applied between the APPLIED PART and
earth.
ACCESSIBLE
METAL PART
Metal part of EQUIPMENT which can be touched without the use of a
TOOL.
APPLIED PART
A part of the EQUIPMENT which in NORMAL USE:
- necessarily comes into physical contact with the PATIENT for the
EQUIPMENT to perform its function; or
- can be brought into contact with the PATIENT; or
- needs to be touched by the PATIENT.
LIVE State of a part which, when connection is made to that part, can cause a
current exceeding the allowable LEAKAGE CURRENT for the part
concerned to flow from that part to earth or from that part to an
ACCESSIBLE PART of the same EQUIPMENT.
SIGNAL INPUT
PART
Part of EQUIPMENT, not being an APPLIED PART, intended to
receive input signal voltages or currents from other equipment, for
example, for display, recording or data processing.
