_____________
1 Scope
Add the following note to Clause 1:
NOTE It can be expected that lamp control gear which comply with this standard will not compromise safety
between 90 % and 110 % of their rated supply voltage in independent use and when operated in luminaires
complying with the safety standard IEC 60598-1 and the relevant part IEC 60598-2-xx and with lamps complying
with the relevant lamp standards. Performance requirements may require tighter limits.
2 Normative references
Add the following reference to the existing list:
IEC 60384-14, Fixed capacitors for use in electronic equipment – Part 14: Sectional
specification: Fixed capacitors for electromagnetic interference suppression and connection to
the supply mains
9 Provisions for protective earthing
Replace the last paragraph of Clause 9 by the following:
The voltage drop between the earthing terminal or earthing contact and the accessible metal
part shall be measured and the resistance calculated from the current and the voltage drop. In
no case shall the resistance exceed 0,5 Ω.

Replace the 6 paragraph of this clause by the following:
Insulation resistance shall be not less than 2 MΩ for basic insulation and 4 MΩ for reinforced
insulation between live parts and the body.
Replace the existing item b) by the following:
b) between live parts and outer metal parts, including fixing screws and metal foil in contact
with outer insulating parts;
14 Fault conditions
th
Add, after the 6 paragraph, the following new paragraph:
Filter capacitors directly connected to the mains supply do not need to be tested if they
comply with IEC 60384-14 and are classified X1 or X2 for the relevant voltage.
Replace the existing Subclause 14.5 by the following new subclause:
14.5 Compliance with 14.1 to 14.4 shall be checked by operating the lamp controlgear at the
rated supply voltage according to the test circuit procedure given in 14.6, with the lamp(s)
connected and the lamp controlgear case at t . Each of the fault conditions outlined in 14.1 to
c
14.4 inclusive shall then be applied in turn.
NOTE For the purpose of this clause the test voltage may be at any value within the supply voltage range of the
control gear, or within ± 5% where only single rated supply voltage is given. This is to allow the high supply current
capacity require of this test.
The tests shall be carried out on three samples for each fault condition, consisting of one or
more items submitted for the purpose of the type test. If one of the samples fails, the test
shall be repeated with three new samples none of which shall fail.
The test shall be continued until stable conditions are obtained. The lamp controlgear case
temperature shall then be measured.
NOTE Components such as resistors, capacitors, semiconductors, fuses, etc. might fail. Such components may
be replaced so as to continue the test.
After the tests, when the lamp controlgear has returned to ambient temperature, the insulation
resistance measured at approximately 500 V d.c. shall be not less than 1 MΩ.
To check whether gases liberated from component parts are flammable or not, a test with a
high-frequency spark generator shall be made.
Accessible parts shall be tested in accordance with Annex A to determine whether they have
become live.
To check whether emission of flames or molten material might present a safety hazard, the
test specimen shall be wrapped with a tissue paper, as defined in 4.187 of ISO 4046-4, and
the latter shall not ignite.
Add a new Subclause 14.6, as follows:
14.6 Connect the controlgear under test to a high-power a.c. supply capable of passing a
−0
fault current of at least 160 A %, as shown in Figure 3. Apply the relevant fault condition.

Series capacitors, if any, shall be short-circuited during the tests.
During the test, the winding temperature and the highest temperature of any part of the lamp

B.9.5.2 Test sequence
The test sequence for the normal winding temperature conditions and the function of the
thermal protector is described as followed:
a) Test of the normal winding temperature conditions plus 20 K
The lamp controlgear shall be operated at thermal equilibrium, under conditions as
specified in Clause H.12, at a short-circuit current (tuned with resistor R) producing a
winding temperature of (t + 20) °C. The thermal protector shall not open under this

condition.
The current I shall be recorded as a basic current for the test b).
tw+20
b) Function test of the thermal protector – control of the marked t temperature limitation

After the test under normal winding temperature conditions with (t + 20) °C, the lamp

w
controlgear shall be operated with an increasing current (in the following steps) until the
thermal protector operates.

Step three with the current of I + 15 %, etc.
tw+20
The procedure of increasing the current in steps of 5 % shall be used until the thermal
protector operates and switches off the contacts.
Between each step, the time taken for the thermal stabilization of the lamp controlgear
shall be observed.
B.9.5.3 Test cycle
The test cycle for different thermal protected controlgear types is as follows.
a) Lamp controlgear with automatic resetting thermal protectors according to B.6.2 a) or with
a protective method of another type according to B.6.2 e)
For lamp controlgear fitted with automatic resetting thermal protectors, or with a protective
method of another type, the test shall be continued until a stable surface temperature is
achieved. The automatic setting thermal protector shall work at least three times by
switching the lamp controlgear off and on under the given conditions.
b) Lamp controlgear with a manual resetting thermal protector according to B.6.2 b)
For lamp controlgear fitted with a manual resetting thermal protector, the test shall be
