The requirements of Clause 13 of IEC 61347-1:2007 apply
General
Electromagnetic controlgear, or their mounting surfaces, shall not attain a temperature which would impair safety
Compliance is checked by the tests of 14.1 to 14.3 and H.12 of IEC 61347-1:2007.
Test requirements
When testing electromagnetic controlgear as per the requirements of sections 14.2 and 14.3, it is essential that the temperature remains within the specified limits outlined in Table 2 for both normal and abnormal conditions.
Before conducting the test, it is essential to verify that the electromagnetic control gear starts and operates the lamp(s) correctly Additionally, the resistance of each winding should be measured at the ambient temperature, if necessary.
After the heating test, the electromagnetic controlgear must cool to room temperature and meet specific conditions: the marking on the controlgear must remain legible, and it must endure a dielectric strength test as outlined in Clause 12 The test voltage should be reduced to 75% of the value specified in Table 1 of IEC 61347-1:2007, with a minimum of 500 V.
Normal operating condition
Under normal testing conditions, electromagnetic controlgear is operated with suitable lamps positioned to ensure that the heat produced does not affect the controlgear's temperature Lamps are considered appropriate if they meet the specified test conditions and allow a current that falls within the tolerances of a reference lamp.
The winding temperature \( t_w \), along with the specified temperature rise \( \Delta t \) of the winding, and the temperatures of capacitors and other components listed in Table 2, must not exceed the values outlined in Table 2 when used with the electromagnetic control gear.
Electromagnetic controlgear windings with temperature rise ∆t are tested under normal conditions with the following details:
– 100 % of rated voltage and at rated frequency,
– until steady temperature is attained
Capacitors and parts listed in Table 2 are tested under normal conditions with the following details:
– 106 % of rated voltage and at rated frequency,
– until steady temperature is attained.
Abnormal operating condition
The abnormal operating conditions test is essential for certain electromagnetic controlgear used with specific metal halide and high-pressure sodium vapor lamps, as outlined in the lamp safety standard IEC 62035, to prevent potential overloading issues.
For electromagnetic controlgear designed in accordance to Annex B of IEC 61347-1:2007,
Amendment 1:2010 the abnormal test is not required
Abnormal operating tests for electromagnetic controlgear are necessary only in built-in luminaires and are integral to their verification process These tests, which assess abnormal circuit conditions, are outlined in IEC 60598-1, Annex C.
Tables 3 and 4 illustrate the relationship between the constants S and the limiting temperature across various winding temperatures (\$t_w\$) Specifically, Table 3 details the endurance test duration of 30 days, while Table 4 presents the results for a 60-day endurance test.

Using materials or manufacturing methods not specified in the table requires that operations be conducted at temperatures not exceeding those proven to be safe for those materials.
The temperatures specified in the table must not be exceeded when operating electromagnetic controlgear at its maximum declared ambient temperature, which is based on an ambient temperature of 25 °C Measurement of the temperature rise of the windings at 100% of rated voltage is non-mandatory unless indicated on the controlgear or in the catalogue However, this measurement is mandatory for circuits that may experience abnormal conditions The declared limiting temperature for windings under such conditions should correspond to at least two-thirds of the theoretical endurance test period to aid in luminaire design Additionally, the temperature of thermoplastic materials, excluding insulation for wiring, is measured to ensure protection against contact with live parts, as outlined in IEC 61347-1:2007.

General
Electromagnetic controlgear designed for metal halide and high-pressure sodium vapor lamps must undergo testing as specified in sections 15.2 or 15.3, particularly for circuits that experience high-voltage impulses.
Electromagnetic controlgear designed for operating in a circuit with a starting device external to the lamp shall be subjected to the test of 15.2
Electromagnetic controlgear designed for operating lamps with an internal starting device shall be subjected to the test of 15.3 The manufacturer shall state which test his product has undergone.
Test for electromagnetic controlgear operating with lamp with external
The six electromagnetic controlgear specified in Clause 5 are tested with a load capacitance of 20 pF, measuring the impulse voltage while the ignitor is in place After removing the ignitor, the dielectric strength of the components exposed to the impulse voltage is subsequently evaluated.
The electromagnetic controlgear is tested with a similar ignitor at 1.1 times the rated voltage, without load capacitance or a lamp, for 30 days If the ignitor fails before the 30-day period ends, it must be replaced each time a breakdown occurs until the full test duration is achieved.
Electromagnetic controlgear which are marked for exclusive use with an ignitor having a time- delay device (see 7.2), are subjected to the same test, but for a period consisting of
250 on/off cycles, keeping an off period of at least 2 min
After conducting the initial test, the voltage test outlined in Clause 12 is performed, where all individual terminations, except for the earthing conductor, are interconnected It is essential that no sparkover or flashover occurs during this process The impulse voltage is subsequently re-measured using the original ignitor and a consistent load capacitance of 20 pF, with any deviation from the original value not exceeding 10%.
Test for electromagnetic controlgear operating with lamps with internal
Using the six samples in 5.1, three samples are subjected to the moisture resistance and dielectric strength test specified in Clauses 11 and 12, respectively
The remaining three samples are heated in an oven until they attain the t w rating temperature marked on the electromagnetic controlgear
Immediately following these pre-conditioning tests, all six samples shall withstand the high- voltage impulse test
The electromagnetic controlgear is tested by connecting it to a d.c supply along with a variable resistor and a circuit-breaker, such as a vacuum switch type H16 or VR 312/412, which has a pull-in time between 3 ms and 15 ms By adjusting the current and operating the circuit-breaker, voltage pulses are induced in the controlgear The current is gradually increased until the peak voltage indicated on the controlgear is achieved, and the voltage pulses are measured directly at the terminations of the electromagnetic controlgear, as illustrated in Figure 1.
If electronic circuit-breakers with a very short pull-in time are used, care should be taken against producing a highly induced pulse voltage
The d.c current value at which the starting voltage is achieved is recorded The samples are subsequently operated at this current for one hour, during which the current is interrupted ten times for three seconds each minute.
Immediately after the test, all six electromagnetic controlgear shall withstand the moisture resistance and dielectric strength test specified in Clauses 11 and 12, respectively

Method for selection of varistors
In order to avoid voltage variations during measurement of voltage pulses, a number of varistors in series is connected in parallel to the electromagnetic controlgear under test
Due to the energy involved, the smallest types of varistors are sufficient for this purpose
The voltage generated in electromagnetic controlgear is influenced by its inductance, direct current, and capacitance C2, as illustrated in Figure 1 of section 15.3 Additionally, the performance of the vacuum switch plays a crucial role, as some of the energy stored in the controlgear is released through the spark that occurs at the switch.
Therefore, it is necessary to select the varistors together with the switch used for the circuit
Due to the fact that the varistors have tolerances which may add or compensate themselves, an individual selection is necessary for each type of electromagnetic controlgear to be tested
The current in the electromagnetic controlgear is first adjusted so that the voltage across C 2
(see Figure 1 in 15.3), is approximately 15 % to 20 % higher than the foreseen test voltage
The voltage is then reduced to the intended value by means of varistors connected in series
For optimal coverage of the test voltage, it is recommended to utilize two or three high-voltage varistors alongside one or two lower voltage varistors to address the remaining voltage range.
The fine adjustment of the test voltage can then be made by varying the current through the electromagnetic controlgear
Approximate values for the voltage of the single varistors can be chosen from the voltage current characteristics given in the relevant varistor data sheets (for example, voltage value at
Explanation of electromagnetic controlgear temperatures
NOTE This annex does not introduce any new proposal but reflects the current state of the requirements
The object of electromagnetic controlgear temperature requirements is to verify that the electromagnetic controlgear functions safely during its intended life
Electromagnetic controlgear life is determined by the quality of the wire insulation connected with the electromagnetic controlgear construction
The thermal behaviour of electromagnetic controlgear is thus characterized by the following aspects: a) endurance; b) electromagnetic controlgear heating; c) test arrangement
The following explanation applies to coil-type electromagnetic controlgear
The winding temperature, denoted as \$t_w\$, is crucial for determining the life expectancy of electromagnetic controlgear, with a target of at least 10 years of continuous operation The relationship between winding temperature and the lifespan of electromagnetic controlgear can be derived from the equation outlined in Figure 1 of IEC 61347-1:2007.
L is the objective test life in days, 30 days being the standard, but the manufacturer may ask for a longer testing time at a related lower temperature;
T is the theoretical test temperature (t + 273) K;
T w is the rated maximum operating temperature (t w + 273) K;
The constant \( S \), which is influenced by the design of the electromagnetic controlgear and the winding insulation, is typically set at 4,500 unless otherwise specified However, manufacturers may assert different values if supported by appropriate testing.
The endurance test can be completed in less than 10 years by using a higher winding temperature While the standard duration for this test is 30 days, it is acceptable to extend the testing period to a maximum of 120 days.
When integrating electromagnetic controlgear into a luminaire, it is essential to ensure that the winding temperature (t w ) of the controlgear does not exceed the specified limits during normal operation, in compliance with luminaire standards.
Under abnormal conditions, such as a short-circuited starter in a fluorescent lamp circuit, it is essential to verify that the temperature limit marked on the electromagnetic control gear is not exceeded This limit corresponds to a lifespan of two-thirds of the test duration for the endurance test of the electromagnetic control gear This requirement is derived from tables outlining limiting and theoretical test temperatures for electromagnetic control gear subjected to a 30-day endurance test, assuming that a t w 90 electromagnetic control gear meets the same requirements as those without temperature markings and with paper-separated layers.
The limiting temperature under abnormal conditions corresponds to a 20-day lifespan for electromagnetic controlgear during a 30-day endurance test This relationship is grounded in the established limits for winding temperatures and the target test temperature for endurance assessments.
However, the manufacturer is free to mark a lower temperature if he so wishes
Verification of luminaires relies on the specified limiting values indicated on the electromagnetic controlgear If a manufacturer opts for a longer endurance test at a lower temperature, the maximum allowable temperature under abnormal conditions is also decreased accordingly.
Originally, electromagnetic controlgear temperatures were checked on an electromagnetic controlgear in a test arrangement which was a simulation of a batten luminaire (see
Figure J.1), modified several times to improve reproducibility The latest test arrangement is with the electromagnetic controlgear lying on wooden blocks (see Figure H.1 of
IEC 61347-1:2007 indicates that previous testing methods showed minimal correlation between the temperatures measured on electromagnetic controlgear and the actual temperatures when integrated into luminaires Consequently, the measurement of electromagnetic controlgear heating in this test setup has been discontinued It has been replaced with a more realistic assessment based on the maximum permitted winding temperature, \( t_w \).
The heating test for electromagnetic controlgear has been adjusted to simulate the most extreme conditions allowed by the manufacturer, based on the specified value of \$t_w\$ Subsequently, the components of the electromagnetic controlgear are evaluated while operating in an oven until the designated winding temperature is achieved.
Verification of electromagnetic controlgear winding temperatures occurs within the luminaire to ensure they do not exceed specified limits These temperatures are measured during both normal and abnormal operating conditions and are compared to the marked values for compliance.
Built-in electromagnetic controlgear designed to be built into enclosures other than luminaires, such as a pole, box or the like, are also tested in the test arrangement of
Figure H.1 of IEC 61347-1:2007 outlines the requirements for built-in electromagnetic controlgear As these controlgear are not integrated into a luminaire, it is essential to verify compliance with the temperature limits set forth in the luminaire standard during this testing arrangement.
Independent electromagnetic controlgear are tested in a test corner The test corner consists of three wooden boards arranged so as to simulate two walls and the ceiling of a room (see
All measurements are carried out in a draught-proof enclosure, as described in Annex F
