1.6 Types of Leakage Current Measurement

Chapter 1 Overview
Total patient leakage current is the total of all leakage current to or from patient connections of all the
same type of applied parts (B-Type, BF-Type and CF-Type applied parts) simultaneously connected.
When there are two or more patient connections that go to different functions and are not electrically con-
nected together, the total patient leakage current for B-Type applied parts must be measured.
If required, measure all patient leakage current components (patient connection - earth, external voltage
on an SIP/SOP, external voltage on an F-type applied part, external voltage on a metal accessible part
that is not protectively earthed.)
(The figure shows patient - earth.)
