_____________
Replace the existing Clause 17 by the following new Clause 17:
17 Abnormal conditions
The ballast shall not impair safety when operated under abnormal conditions at any voltage
between 90 % and 110 % of rated supply voltage or range of rated supply voltage declared by
the manufacturer.
Compliance is checked by the following test.
Each of the following conditions shall be applied with the ballast operating to the
manufacturer’s instructions (including a heat sink, if specified) for 1 h:
a) lamp is not inserted or does not ignite;
b) burner leaks;
c) the lamp operates, but rectifies.
Condition a) is tested with open output.
Condition b) is tested with circuit in Figure 1 (see below).

Condition c) is tested with circuit in Figure 2 (see below).
The lamp in the circuit is replaced by test circuit as shown in Figure 2.
Both current directions have to be checked: ballast terminal 1 with circuit wire 1 and ballast
terminal 1 with circuit wire 2.
The control gear is stabilised at the ambient temperature of the draught-proof enclosure
between 10 °C and 30 °C.
The resistor R has to be chosen such that the electrical operating conditions are the same as
with the lamp. An appropriate resistance value can be found by calculation:
R = U / P
