ZZ.1 Introduction
This Annex sets out variations between this Standard and IEC 60950-1:2001. These variations indicate
national variations for purposes of the IECEE CB Scheme and will be published in the IECEE CB Bulletin.
These variations are indicated within the body of the Standard.

1.2.12.201
POTENTIAL IGNITION SOURCE:
Possible fault which can start a fire if the open-
circuit voltage measured across an interruption or
faulty contact exceeds a value of 50 V (peak) a.c.
or d.c. and the product of the peak value of this
voltage and the measured r.m.s. current under
normal operating conditions exceeds 15 VA.
Such a faulty contact or interruption in an
electrical connection includes those which may
occur in CONDUCTIVE PATTERNS on PRINTED
BOARDS.
