60601-1(ed.2);am1;am2
Standard(s)- (year and edition):
IEC 60601-1:1988 Ed.2 Am1+Am2
Sub clause(s): 17 g)
Sheet n°: DSH-405
Subject: Leakage current in secondary circuits
Key words: Leakage current, secondary circuit
Confirmed by CTL at its 39th meeting, in Cologne
Question:
If secondary circuit impedances limit the leakage current, is further investigation of secondary
circuits required? (refer to sub-clause 52.5).
Decision:
Secondary circuits providing protective means after short-circuiting of inadequate AIR
CLEARANCE and CREEPAGE DISTANCE must be investigated. Failure of components in
these circuits shall be investigated as a SINGLE FAULT CONDITION. Failure of such
components shall be investigated as a SINGLE FAULT CONDITION.
