base material of printed boards, on

which the available power at a connection

exceeds 15VA operating at a voltage

exceeding 50V and equal or less than

400V (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

Base material of printed boards, on which

the available power at a connection

exceeds 15VA operating at a voltage

exceeding 400V (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 chose 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 4kV (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.
