1.Scope This document specifies the product classification, requirements, inspection rules, marking, packaging, transportation, and other aspects of self-ballasted electrodeless fluorescent lamps (hereinafter referred to as "lamps"). Storage, and the corresponding experimental methods are described. This document applies to lamps with a rated voltage of 220V and a frequency of 50Hz, using screw-in or bayonet-type lamp holders, for general lighting in households and similar settings. The lights.

4 Classification and Model

4.1 Product Classification Lamps are classified according to the form of their discharge tubes. double tube, four tube, multi tube, spiral, ring, spherical, reflective, etc., and their types should conform to GB/T Requirements of Appendix E in 17262-2011.

4.2 Model Number Designation Rules The rules for naming lamp models are as follows:

5 Requirements

5.1 Safety Requirements The safety requirements for lamps shall comply with the requirements of GB 21554.

5.2 External Dimensions of the Lamp The dimensions of the lamp shall conform to the manufacturer's specified specifications, and the lamp holder shall conform to the requirements of GB/T 1406.1 or GB/T 1406.5.

6 Test Methods

6.1 General Requirements for Testing The photoelectric parameters of the lamp should be measured in an environment with an ambient temperature of 25°C±2°C and a relative humidity of no more than 65% without convection. conduct. During stabilization, the power supply voltage should remain within ±0.5%; during measurement, it should drop to within ±0.2%. For lifespan... The test results should be stable within ±2%. The total harmonic distortion (THD) of the power supply voltage should not exceed 3%. The percentage of THD to the fundamental frequency is the root mean square of each harmonic component. sum. All tests should be conducted at the rated frequency, and the lamp should be placed in free space with the lamp head pointing vertically upwards.

6.2 Dimensional Test The external dimensions of the lamp are measured using a measuring tool with an error of no more than

0.05 mm. The lamp holder shall be inspected using the gauges specified in GB/T 1483.1 or GB/T 1483.5.

6.3 Start-up performance test The test methods for startup time, settling time, and rise time shall be carried out in accordance with the provisions of section

5.4 of GB/T 17263-2025.

6.4 Testing of photoelectric parameters The test methods for lamp power and power factor shall be carried out in accordance with the provisions of section

5.5 of GB/T 17263-2025. The initial luminous efficacy/luminous flux and color characteristics of the lamp are tested according to the provisions of section

5.6 of GB/T 17263-2025.The luminous efficacy of the lamp... It was calculated.

6.5 Life Characteristics Test The median life and luminous flux maintenance of the lamps shall be tested in accordance with the provisions of section

6.5 of GB/T 17263-2025.

6.6 Electromagnetic Compatibility Characteristics Test The electromagnetic compatibility characteristics of a lamp include radio interference characteristics, harmonics, and electromagnetic compatibility immunity. Tests are conducted according to GB/T 17743,... The requirements of GB 17625.1 and GB/T 18595 shall be followed.

6.7 Marking Test The correctness and clarity of the light signs are checked visually. The durability of the light signs is checked by wiping them with a damp cloth for 15 seconds, allowing them to dry, and then wiping them with a cloth dampened with [unclear - possibly a substance or ingredient]. Wipe with a cloth containing alkyl for 15 seconds. After the test, the marking should still be clearly visible.

7 Inspection Rules

7.1 Producers shall conduct delivery inspection and type inspection on the products they produce.

7.2 The lamps for the acceptance test shall be evenly drawn from the same model of lamps produced in each shift. The acceptance test shall be conducted in accordance with GB/T 2828.1. The inspection items, sampling plan, inspection level and acceptance quality limit (AQL) shall be specified in Table 3.

7.3 Lamps for type testing shall be evenly drawn from those that have passed the acceptance test, and this shall be done at least once a year. Whenever production is suspended for six months... Routine tests should be conducted whenever the design, manufacturing process, or materials of the lamp are changed, or when the lamp's performance may be affected. Type testing shall be conducted according to the single sampling plan of discrimination level I of GB/T 2829, including the test items, rejection quality limit (RQL), and sampling...
