NOTE 1 – If the enclosure does not withstand the glow-wire test the appliance is 
considered to have failed to meet the requirements of Clause 21.201 without the 
need for consequential testing.  
NOTE 2 – If other parts do not withstand the glow-wire test due to ignition of the 
tissue paper and if this indicates that burning or glowing particles can fall onto an 
external surface underneath the apparatus, the apparatus is considered to have 
failed to meet the requirements of Clause 21.201 without the need for 
consequential testing  
NOTE 3 – Parts likely to be impinged upon by the flame are considered to be 
those within the envelope of a vertical cylinder having a radius of 10 mm and a 
height equal to the height of the flame, positioned above the point of the material 
supporting, in contact with, or in close proximity to, connections.  
 
20.201.2.4 Testing of printed boards  
The base material of printed boards shall be subject to the needle-flame test of 
Clause 21.201.2.3. The flame shall be applied to the edge of the board where the 
heatsink 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 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 V-1 or better according to AS/NZS 60695.11.10, or the printed boards 
are protected by an enclosure meeting the flammability category V-0 according to 
AS/NZS 60695.11.10, 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 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 V-0 according to AS/NZS 60695.11.10 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 power is the maximum power which 
can be drawn from the supplying circuit through a resistive load whose value is 
chosen to maximize the power for more than 2 min when the circuit supplied is 
disconnected.  
 
21.201.3 For open circuit voltages greater than 4 kV potential ignition sources 
with open circuit voltages exceeding 4 kV (peak) a.c. or d.c. under normal 
operating conditions shall be contained in a fire enclosure which shall comply 
with flammability category V-1 or better according to AS/NZS 60695.11.10.
