4.7.201
4.7.201.5 Testing of printed boards
The base material of printed boards shall be
subjected to the needle-flame test of Clause
4.7.201.3. The flame shall be applied to the edge
of the board where the heat sink effect is lowest
when the board is positioned as in normal use.
The flame shall not be applied to an edge,
consisting of broken perforations, unless the edge
is less than 3 mm from a POTENTIAL IGNITION
SOURCE.
The test is not carried out if the –
- Printed board does not carry any POTENTIAL
IGNITION SOURCE;
- Base material of printed boards, on which the
available apparent power at a connection exceeds
15 VA operating at a voltage exceeding 50 V and
equal or less than 400 V (peak) a.c. or d.c. under
normal operating conditions, is of flammability
category FV-1 or better according to AS/NZS
4695.707, or the printed boards are protected by
an enclosure meeting the flammability category
FV-0 according to AS/NZS 4695.707, or made of
metal, having openings only for connecting wires
which fill the openings completely; or
- Base material of printed boards, on which the
available apparent power at a connection exceeds
15 VA operating at a voltage exceeding 400 V
(peak) a.c. or d.c. under normal operating
conditions, and base material of printed boards
supporting spark gaps which provides protection
against overvoltages, is of flammability category
FV-0 according to AS/NZS 4695.707 or the
printed boards are contained in a metal enclosure,
having openings only for connecting wires which
fill the openings completely.
Compliance shall be determined using the
smallest thickness of the material.

NOTE: Available apparent power is the maximum
apparent power which can be drawn from the supplying
circuit through a resistive load whose value is chosen to
maximise the apparent power from more than 2 min
when the circuit supplied is disconnected.

ATTACHMENT: CANADIAN DIFFERENCES
Test results according to CB BULLETIN No. 109A, December 2005

Result – Remark
Verdict
Canada and the United States of America have adopted a single, bi-national standard, CAN/CSA
C22.2 No. 60950-1/UL60950-1, First Edition, which is based on IEC 60950-1, First Edition. Effective
April 1, 2003, this standard may be used for product certification immediately, however, the
previous version of the standard may also be used until April 1, 2005.
Note: The previous version is CAN/CSA C22.2 No.60950-00/UL 60950 Third Edition, based on IEC
60950, 3rd Edition. Refer to the “IEC 60950, 3rd Edition, CA” section of this CB bulletin for the
national differences in this version of the standard. This bi-national standard should be consulted
for further details on the Special National Conditions and Other Differences
SPECIAL NATIONAL CONDITIONS
Those requirements are identified as Special National Conditions since they are directly related to
the Canadian Electrical code (CEC), Part 1 and the Canadian Building Code, which are referenced
in legislation and which form the basis for the rules and practices followed in electrical and other
building installations in Canada.
Notes:
• “CEC” denotes Canadian Electrical Code.
• “NEC” denotes US National Electrical Code.
• Due to common Canadian and US national differences, products that are in compliance with the
Canadian national differences are also considered in compliance with the US national differences.
