3.1 The design and structure of self-ballasted lamps shall ensure that the lamps function reliably in normal use and will not cause harm to users and the surrounding environment. Generally speaking, all specified items shall be tested when checking eligibility. 3.2 Unless otherwise specified, all test items shall be tested at rated voltage and rated frequency in a test room with a temperature of 25℃±1℃ and no convection.
If the voltage range is marked on the lamp, the average value of the voltage range shall be taken as the rated voltage. 3.3 The various components of self-ballasted lamps are factory-sealed and cannot be repaired. They must not be opened for testing. If it is necessary to inspect the lamp and test its circuit, the manufacturer or seller should be consulted to provide lamps specially designed for simulating abnormal conditions (see Chapter 12). 4 Marking
4.1 The lamp should have the following clear and firm indications: a) Source mark (which may take the form of a trademark, manufacturer or seller's name). b) Rated voltage and voltage range (expressed in "V" or "volt"). c) Rated power (expressed in \W\ or "watt". d) Rated frequency (expressed in "Hz".
4.2 The manufacturer shall add the following markings on the lamp, on the packaging, or in the instructions for use: a) The current of the lamp.
b) If the burning position of the lamp is restricted, indicate this on the mark. c) If the weight of the replacement lamp significantly exceeds the weight of the replaced lamp, it should be noted that the increased weight may reduce the mechanical stability of some lamps.
d) The specific conditions and restrictions that the lamp must comply with when used, such as when used in a dimming circuit. 4.3 Check its compliance in accordance with the following clauses: a) Use the appearance method to check whether the marking required by 4.1 and the clarity of the marking are present. b) Check the durability of the marking in the following way: Use a cloth dampened with water to gently wipe the mark for 15 s, wait for it to dry, and then wipe it with a piece of cloth dipped in hexane for 15s.

5.3 The mass of a self-ballasted lamp with a B22d lamp cap or an E27 lamp cap shall not exceed 1kg, and the bending moment between the lamp and the lamp holder shall not be greater than 2N·m.
Compliance shall be checked by measurement.
6 Prevention of electric shock
Self-ballasted lamps shall be so designed that, when screwed into a lampholder complying with IEC 238 without any auxiliary housing in the shape of a lamp, no metal parts inside or on the lamp cap can be touched. Compliance is checked by the test finger specified in Figure 1, applying a force of 10 N if necessary. Lamps with Edison screw caps shall be designed to comply with the requirements for protection against accidental contact for lamps for general lighting (GLS). Compliance may be checked with the aid of the gauges specified in 7006-51A of the latest version of IEC 61-3 for testing E27 caps. Test requirements for self-ballasted lamps with E26 caps are under consideration. Test requirements for self-ballasted lamps with B22 caps are the same as for incandescent lamps with the same cap. No metal parts external to the cap, other than current-carrying metal parts on the cap, shall be live or liable to become live. For the test, any removable conductive material shall be placed in the most unfavourable position without the use of tools. Compliance is checked by the insulation resistance and dielectric strength tests (see clause 7). 7 Insulation resistance and dielectric strength after humidity treatment Adequate insulation resistance and dielectric strength shall be present between the current-carrying metal parts of the lamp and the parts of the lamp that may be touched. 7.1 Insulation resistance
The lamp shall be placed in a humidity chamber with a relative humidity of 91% to 95% for 48 hours. The air temperature in the chamber shall be controlled at any value between 20℃ and 30℃, with a temperature difference within 1℃.
The insulation resistance shall be measured in a humidity chamber. A DC voltage of approximately 500V shall be applied to the lamp. After 1 minute, the insulation resistance test shall be started. The insulation resistance between the current-carrying metal parts of the lamp cap and the accessible lamp parts (a layer of metal foil shall be wrapped on the insulating parts of the lamp that may be touched during the test) shall not be less than 4 MQ. The insulation resistance between the housing and the contacts of the B22 lamp cap is under study. 7.2 Dielectric strength
The dielectric strength test shall be carried out immediately after the insulation resistance test. During the test, the following AC voltage test shall be applied to the above-mentioned specified positions for 1 min.
ES lamp holder: Between the housing of the screw-type lamp holder and other accessible parts of the lamp (a layer of metal foil is wrapped on the accessible insulating parts):
HV type (220V~250V): 4000V (effective value) BV type (100V~120V): 2U+1 000V
U-rated voltage
During the test, the housing of the lamp holder and the eye piece shall be short-circuited. At the beginning, the applied voltage shall not exceed half of the specified voltage value, and then the voltage shall be gradually increased to the above-mentioned specified value. 78
GB16844-1997
The test shall be carried out in a humid chamber, and arcing and breakdown are not allowed during the test. The distance between the metal foil and the current-carrying parts is under study. B22 Lamp holder: between the shell and the electrical contacts (under study). 8 Mechanical strength
Torque resistance
When conducting the following torque test, the lamp holder should be firmly bonded to the lamp body or the part of the lamp used to screw in or out: B22d ***-
E26 and E27
The test adopts the test lamp holder shown in Figures 2 and 3. The torque should not be applied suddenly, but should be gradually increased from zero to the specified value. 3N*m
For lamp holders that are not fixed by bonding, relative movement between the lamp holder and the lamp body is allowed, but it shall not exceed 10°. After the mechanical strength test, the sample lamp shall meet the accessibility requirements (see Chapter 6). 9 Lamp holder temperature rise
Measure the lamp holder temperature rise t of the finished lamp in accordance with IEC360. When the lamp is started, stabilized and after stabilization, its temperature rise shall not exceed the following specified values:
Under study
The above temperature rise values ​​are the same as those of 60W (maximum power) incandescent lamps and are used to prevent incandescent lamps from overheating. The heat resistance of incandescent lamps is tested with a hot test source (HTS) bulb. All tests shall be carried out at rated voltage. If only a voltage range is marked on the lamp, the average value of the voltage range shall be used for testing, but the upper and lower limits of the voltage range shall not differ from its average voltage value by more than 2.5%. For lamps with a wide voltage range, the highest value in the range shall be used for testing.
10 Heat resistance
Self-ballasted lamps shall have sufficient heat resistance. The external anti-electric shock insulating parts of the lamp and the insulating parts that fix the live parts shall have sufficient heat resistance.
Compliance shall be checked using the ball pressure test device shown in Figure 4. The test should be carried out in a heating box, and the temperature in the box should be 25℃±5℃ higher than the normal working temperature of the relevant parts in Chapter 9. For insulating parts that fix live parts, it should be at least 125℃, and for other parts it should be 80℃". The surface of the test part should be placed horizontally, and a steel ball with a diameter of 5mm is pressed on the surface of the test part with a force of 20N. Before the test, the test load and support device are placed in the heating box and heated for a sufficient time to ensure that they reach a stable test temperature.
Before applying the test load, the test part should be placed in the heating box and heated for 10 minutes. During the test, if the test surface is bent, the part pressed by the steel ball should be supported. For this reason, if it is not possible to test on a complete sample, an appropriate part can be removed from it for testing. The sample thickness should be at least 2.5mm. If the sample cannot reach such a thickness, two or more samples can be placed together. After 1h, remove the steel ball from the test part, soak the test part in cold water for 10min, and measure the indentation on the test part after it cools to near room temperature. Its diameter shall not exceed 2mm. * Under study.
GB168441997
If the curved surface makes the indentation elliptical, its short axis should be measured and the length is the indentation diameter. If in doubt, measure the indentation depth and calculate the diameter using the formula = 2VP(5-P), where P is the indentation depth. Ceramic parts are not tested for this test. 11 Fire and flame retardancy
Insulating parts that fix live parts and insulating parts that protect against external electric shock should be able to withstand the glow filament test specified in IEC695-2-1: a sample is a finished lamp. In order to conduct the test, irrelevant parts can be removed from the lamp, but it must be ensured that the test conditions are basically consistent with the conditions in practical use.
- Install the sample on the bracket and apply a force of 1N to press it against the top of the glow filament. The distance between the filament and the upper part of the specimen should preferably be 15mm or more, and it should be in the center of the test surface. The depth of the glow filament penetrating the specimen should be limited to 7mm by mechanical methods. If the test cannot be carried out according to the above requirements because the specimen is too small, a piece of the same material can be taken as the test sample. The sample is 30mm square and its thickness is the minimum thickness of the finished sample. - The temperature of the top of the glow filament is 650℃. After 30s, the sample is removed from the top of the glow filament. Before starting the test, the temperature and heating current of the glow filament should be constant for 1 min. However, it should be ensured that the thermal radiation does not affect the sample during this period. The temperature of the top of the glow filament is measured by an armored high-sensitivity thermocouple wire. The structure and calibration of the thermocouple should comply with the requirements of IEC695-2-1.
After a sample is removed from the glow filament, any burning flame on the sample shall be extinguished within 30 seconds, and any burning falling material shall not ignite a thin paper placed horizontally below the sample at a distance of 200mm±25mm. This test is not performed on ceramic parts. 12 Abnormal conditions
Self-ballasted lamps may have abnormal conditions in specific uses, but operation under abnormal conditions should not reduce their safety performance. The following abnormal condition tests are carried out in sequence, as well as other abnormal conditions associated with them. One sample is used for each abnormal condition test. a) In the switch start circuit, the starter is short-circuited. b) Short circuit between capacitors.
c) The lamp does not start due to damage to one cathode.
d) Although the cathode circuit is intact, the lamp does not start (deactivated lamp). e) The lamp operates, but one cathode is deactivated or damaged (rectifier effect). f) Other contacts in the circuit are disconnected or bridged, and the circuit diagram shows that this abnormal condition may reduce the safety performance of the lamp. The inspection of the lamp and its circuit diagram shall generally give the abnormal conditions to be carried out. When carrying out the abnormal condition test, it shall be carried out in the most convenient order.
The manufacturer or seller shall submit the special lamp for the abnormal condition test and provide, as far as possible, the method of carrying out the abnormal condition test by operating the switch outside the lamp. Parts or devices that cannot be short-circuited shall not be connected across. Similarly, parts or devices that cannot be opened shall not be disconnected. The manufacturer or seller shall provide proof that the parts of the lamp have performance that does not reduce its safety, such as stating that they comply with the relevant standards. For abnormal conditions a), b) or f), compliance is checked by the following method: the lamp under test is ignited at room temperature and the voltage applied is 90% and 110% of the rated voltage. If it is a voltage range, it is 90% and 110% of the average value of the voltage range. Until a steady state is reached, the abnormal condition test is then carried out.
For abnormal conditions c), d) or e), the operation method is the same as above, but the abnormal condition is introduced at the beginning of the test. The lamp is then tested for 8 h, during which it shall not catch fire or develop flammable gases and live parts shall not become accessible.
Use a high frequency spark generator to verify whether the gases released from the parts are flammable. Verify that accessible parts can become live in accordance with the test required in clause 6. Verify the insulation resistance with a direct voltage of approximately 1 000 V (see 7.1).
