Applied parts

As an introduction, the different types of applied parts will be described in the following. According to

IEC 60601-1, an applied part is a part of the device which for its intended use

- necessarily comes into physical (bodily) contact with the patient so that the device can fulfil its

function or

- can be brought in contact with the patient or

- needs to be touched by the patient.

An insulated (unearthed) applied part of type F is described as:

anappliedpartwhichisisolatedfromotherpartsofthedeviceinsuchawaythatthecurrentowing

is not higher than the patient leakage current admissible for the first fault, if an unintended voltage

from an external source is connected to the patient and thus is applied between the applied part

and earth.

Applied parts of type F are either applied parts of type BF or applied parts of type CF.

Note:FordevicesofprotectionclassI,thisappliedpartisconnectedtoearthwhichcanbeveried

by measurement with an ohmmeter.

Applied part of type B:

This is an applied part which provides protection against electric shock in compliance with the re-

quirementsdenedinIEC601-1,especiallyconsideringtheadmissibleleakagecurrent,andwhich

is marked as follows:

- type B: earthed applied part or

- typeB:appliedpartprotectedbyadebrillator

Applied parts of type B are not intended for being applied directly to the heart.

Applied part of type BF:
