Some standard content:
GB18661—2002
Articles 5.3, 5.6, 5.7, 5.13, and a) and b) of Article 8.1 of this standard are mandatory, and the rest are recommended.
This standard specifies the technical requirements, test methods, inspection rules, etc. of single-ended metal halide lamps (175W1500W sodium series). This standard is formulated on the basis of non-equivalent adoption of the American national standard ANSIC78.1375~1379 "Metal Halide Lamps" and combined with the actual development of metal halide lamps in my country in recent years. The electrical parameters in this standard are consistent with those in the American national standard. Since the light parameters, color parameters and life are not specified in the American national standard, this standard formulates the various index values of light parameters, color parameters and life based on reference to product samples of advanced foreign enterprises, actual measured data of foreign samples and enterprise standards of major domestic metal halide lamp manufacturers. In addition, this standard summarizes the products of the current major domestic manufacturers and formulates the technical requirements for single-ended lighting metal halide lamps of various specifications produced by four types of glass bulbs, including ED type, BT type, T type, and TT type. Appendix A and Appendix B of this standard are the appendices of the standard. This standard is proposed by the China Light Industry Federation. This standard is under the jurisdiction of the Electric Light Source and Accessories Standardization Technical Committee of the National Technical Committee for Standardization of Lighting Appliances. This standard was jointly drafted by Hangzhou Lighting Appliance Co., Ltd., Philips Yaming Lighting Co., Ltd. and Beijing Electric Light Source Research Institute. The main drafters of this standard are: Wu Yongqiang, Shen Jiping, Cai Jianlong, Huang Pei, Cao Yili, Zhou Yongfa, and Zhang Ruo. 676

6.7 The assembly quality of the bulb (5.5) is checked by visual inspection and special equipment. 6.8 The initial and end-of-life torque (5.6) are checked by a torque meter. 6.9 The electrical clearance (5.7) is measured by a vernier caliper. 6.10 The steady-state damp heat test (5.8) of the bulb is carried out in accordance with the requirements of GB/T2423.3. The test sample is placed in a test chamber with a temperature of (40±2)℃ and a relative humidity of 90% to 95% for 48 hours without packaging and without power. Take out the test sample and restore it under normal atmospheric pressure for 1 hour. Visually check that there is no rust on the metal at the bottom of the lamp cap. 6.11 The vibration test of the lamp (5.9) shall be carried out in accordance with the provisions of GB/T2423.10. The appearance inspection of the sample before the test shall meet the requirements of 5.2. The sample shall be fixed on the vibration table with a rigid connection. The test is a fixed frequency test with a frequency of 50 Hz and an amplitude of 1 mm (single amplitude). The duration is 10 minutes of vibration on two mutually perpendicular axes. 6.12 The test methods for the restart voltage spike of the lamp (5.10), the restart voltage of the lamp (5.11), the starting voltage and temperature rise requirements of the lamp (5.12) shall be carried out in accordance with the provisions of QB/T2515. 6.13 Measurement of the maximum temperature of the glass bulb and the lamp cap 6.13.1 Thermocouple method
a) Thermocouples are surface contact type and should absorb the least energy. When the lamp is off, the reading obtained by extrapolation to the zero time can minimize the radiation energy effect of the thermocouple.
b) The contact pressure of the thermocouple junction on the glass bulb or lamp cap should be sufficient to ensure that it does not affect the measured temperature. c) If the potentiometer has no room temperature compensation adjustment, an ice water tank should be used as the reference contact. d) Because temperature equilibrium may take a considerable time, readings should be taken at intervals of 15 minutes until the last two consecutive readings are the same.
e) In order to determine the highest temperature, a certain number of points on the glass bulb should be measured. 6.13.2 Thermocouple method for measuring lamp cap temperature The method for measuring the temperature rise of the lamp cap is shown in QB/T2512. The lamp cap temperature is measured using a lamp with a lamp fixture. In order to estimate the influence of the lamp fixture on the lamp cap temperature, it is obvious that a metal sleeve cannot be used here. In this case, the thermocouple should be directly attached to the lamp cap shell, as close as possible to the connection between the lamp cap and the glass bulb. 6.13.1 a), c), d) can also be used to measure the lamp cap temperature. 6.13.3 Infrared radiation method for measuring glass cap temperature a) The instrument used should be sensitive to radiation of only a certain wavelength. b) This wavelength cannot be transmitted by glass to avoid the influence of heat inside the lamp glass, especially inside the arc tube. c) This wavelength is not absorbed by the atmosphere. In fact, the wavelength is limited to 4.8μm~~5.6μm. d) 6.13.1 e) is applicable to this measurement method. 6.14 The average life and lumen maintenance test (5.14) of the lamp is carried out at rated voltage, using a working ballast (see Appendix A) and a 50Hz AC power supply, and the voltage fluctuation should not be greater than ±2%. During the life test, the lamp should be ignited as specified. The lamp is turned off twice a day and night, each time for not less than 1 hour. The off time should not be counted in the life of the lamp. 6.15 The firmness and vibration resistance of the package (8.2) are tested by a drop test. a) Pack the inspected samples, weigh each box and keep records; b) Determine the drop height according to Table 9;
c) Adjust the drop platform on the drop tester to the specified height; d) Place the packaging box containing the samples on the platform for the drop test; e) Drop each box twice (the bottom surface is parallel to the ground and falls face down. The bottom surface parallel to the ground is rotated 45 degrees along a long edge of the bottom surface as the axis, and then falls face down parallel to the ground):
) After the test, check whether the packaging is intact and whether the bulb can start and ignite normally. 683

If the delivery inspection is unqualified, the batch of products shall be isolated by the manufacturer and 100% inspected. After rejecting the unqualified products, they can be submitted for acceptance again. The re-delivery inspection is only allowed once, and a brief description of the number of unqualified products and the reasons after the batch of products is picked out should be attached. If the batch is still unqualified after the re-submission inspection, the delivery should be stopped. At this time, the reasons should be analyzed, and improvement measures and methods for handling the batch of products should be proposed.
7.3 Routine inspection

7.3.1 The routine inspection cycle should be once a year. When the structure, process or material of the bulb changes may affect the performance of the bulb, or when the production of the bulb is interrupted for more than three months and then resumed, routine inspection should be carried out. 7.3.2 Before routine inspection, all sample units should be 100% inspected according to the delivery inspection items. If unqualified products are found, they will be replaced with qualified products. At the same time, the reasons should be analyzed and recorded in the routine inspection report, but they will not be used as the basis for the identification of routine inspection results. 7.3.3 Routine inspections shall be carried out in accordance with the provisions of GB/T2829 and the contents listed in Table 11.
