Some standard content:

GB 7000.1—1996 | IEC598-1:1992 "Luminaires Part 1: General requirements and tests" is completely equivalent.
In this way, by making my country's lighting safety standards equal to international standards, we can adapt to the needs of international trade, technical and economic exchanges, and international quality certification as soon as possible.
When revising GB7000--86, according to the provisions of Chapter 1 of GB1.11993 "Standardization Work Guidelines Unit 1: Rules for Drafting and Presentation of Standards Part 1: Basic Provisions for the Preparation of Standards", The format and method of writing this standard are consistent with the equivalent IEC598-1:1992.
Since my country’s wire and cable models are different from IEC, my country’s wire gauges are used in this standard. In addition, some of the other IEC standards cited in IEC598-1:1992 have been formulated as national standards or industry standards in my country, and some have not yet been formulated in my country. In this standard, those that have been formulated as Chinese standards are listed as Chinese standards. Standard number, and use parentheses to list the corresponding IEC standard number and standard name; if it has not been formulated as a Chinese standard, it shall be determined according to GB1.22-1993 "Standardization Work Guidelines Unit 2: Method for Determining Standard Content Part 22: Cited Standards" The provisions of 5.7.2 in "Regulations" directly quote international standards and list the IEC standard number and standard name. This standard will replace GB7000-86 from the date of entry into force. Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, Appendix F, Appendix G, Appendix H, Appendix J and Appendix K of this standard are all standard appendices.
Appendix L, Appendix M, Appendix N, Appendix P, and Appendix Q of this standard are all reminder appendices. This standard is proposed by China Light Industry Federation.
This standard is under the jurisdiction of the National Lighting Standardization Center. This standard was drafted by: Shanghai Lighting Research Institute. The main drafters of this standard are: Yao Zhishang and Wang Baisong. GB7000.1-1996 | | tt | As close to a consensus as possible. 2) These decisions or protocols are in the form of recommendations for use by States and in this sense have been endorsed by the respective National Committees. 3) In order to promote international unification, IEC hopes that to the extent possible, all national committees should adopt the texts recommended by IEC as their national standards. Any differences between IEC recommended standards and corresponding national standards should be noted at the end of the national standard whenever possible.
4) IEC has not established any procedures for expressing approval marks. If a piece of equipment is claimed to comply with one of IEC's recommended standards, IEC is not responsible for this.
This standard was developed by IEC Technical Committee 34 (Lamps and Equipment), Subcommittee 34D (Lamps). This standard is the third edition of IEC598-1, replacing its second edition in 1986 and the first amendment in 1988.

Replaces GB7000— 86
This standard specifies the classification, marking, basic requirements for mechanical and electrical structure of lamps and related tests. This standard applies to lamps using tungsten filament lamps, tubular fluorescent lamps and other gas discharge lamps with a power supply voltage not exceeding 1000V. This standard includes safety requirements in all aspects (electrical, thermal and mechanical, etc.). The provision of optical parameters of luminaires falls within the performance requirements of the luminaire and is not included in this standard. This standard includes requirements for luminaires with triggers whose nominal pulse voltage peak does not exceed the values ??in Table 11.2. These requirements also apply to luminaires with the trigger inside the ballast and luminaires with the trigger separated from the ballast. Requirements for luminaires with triggers within the bulb are being studied.
This standard contains requirements for semi-luminaires.
In general, this standard covers the safety requirements for lamps. The purpose of developing this standard is to provide a series of common requirements and tests that are applicable to most types of lamps and are based on the specific provisions of various lamp standards. Therefore, this standard should not be regarded as all technical regulations for any type of lamps. The provisions of this standard only apply to various specific types of lamps within the scope determined by the corresponding chapter of IEC598-2 (see Article 0.6 of this standard).
When various lighting standards refer to the requirements of a certain chapter of this standard, they stipulate the degree of applicability of the chapter, the test sequence and some necessary additional requirements. Therefore, the order intended in this standard has no special significance. The standards for each type of lighting fixtures are independent and there is no need to refer to the standards for other types of lighting fixtures. If the requirements of a certain chapter in this standard are quoted in various lighting standards, and the words "Apply Chapter 7000" appear, the meaning is: except for those that are obviously not applicable to the requirements of a certain chapter in this standard. Except for the requirements for a specific type of luminaire, all the requirements of this chapter of this standard apply.
As "lighting design data", the maximum size of the bulb shape and other relevant data in GB7249 and the light source standard should be referred to. Inspection according to the maximum size conditions of the bulb shape is not part of the lamp finalization test. 0.2 Referenced standards

Lamps should be designed and manufactured to work safely under normal use without causing harm to people and the surrounding environment. Qualification generally passes all specified tests Carry out inspection
0.3.1 Lamps should comply with the requirements of the corresponding standards for various types of lamps. If there is no corresponding category standard for a specific type of lamp, the nearest suitable category standard for lamps can be used as the standard. Reference for requirements and testing of this luminaire. Where a luminaire is designed as a combination of two or more types of luminaires, the luminaire shall comply with all applicable category luminaire standards. 0.3.2 For testing purposes, half-luminaires shall be treated as luminaires. 0.4 General test requirements
0.4.1 The tests in this standard are type tests. For the definition of "type tests", see Chapter 1 of this standard. 0.4.2 Unless otherwise stated in this standard and various lighting standards, lamps should be tested at an ambient temperature of 10°C to 30°C. The luminaire should be installed and powered on in accordance with the manufacturer's installation instructions for testing under normal use conditions. Unless necessary for testing, light bulbs are generally not included.
If the internal wiring is incomplete, the luminaire cannot be considered to comply with the requirements of this standard. Generally, a sample is selected for testing. If it is a series of similar lamps, one lamp for each rated power can be selected, or a representative lamp from the series can be selected for testing with the consent of the manufacturer. Samples include lamps and accessories. From a testing perspective, the most unfavorable combination of luminaires and accessories should be selected for testing. Each lamp sample shall be subjected to all appropriate tests. In order to shorten the test time and conduct some tests that may be destructive, the manufacturer should provide additional lamps or lamp components. As long as the materials and design of these lamps or lamp components are the same as those of the original lamp, the test results will be the same as those of the original lamp. When visual inspection is used for qualification testing, necessary operations should also be included. For track-mounted lamps, the manufacturer shall provide samples of the lamps as well as the corresponding tracks, couplers, and adapters of the connected lamps.
Combined lighting fixtures must be tested to see if they meet safety requirements when the assembly of components is at its worst. Certain parts of the luminaire, such as connectors and lifting devices, can be tested independently as long as their performance is designed to be independent of other parts of the luminaire.
Lamps that use non-detachable cords or flexible cables should be connected to the luminaire during the test. For lamps and lanterns that use a lampshade, but the lamp does not come with a lampshade, the manufacturer should provide a typical type of lampshade that can be used for the lamp. 0.5 Lamp components
0.5.1 Except for the overall components, all components shall comply with the requirements of the IEC standards relevant to the component. As part of the lamp, the overall component should comply with component standards as much as possible. Note: This does not mean that components need to be tested individually before approval of the luminaire. 0.5.2 For those components that meet the relevant standards, only those requirements in the luminaire standard that are not included in the standard of the component should be tested. Lamp holders and starter holders shall additionally comply with the specifications and interchangeability requirements of their respective standards so that they can be properly incorporated into lamps. 0.5.3 For components that do not have corresponding standards, as part of the lamp they shall comply with the standards for that type of lamp. related requirements. Lamp holders and starter holders GB 7000.1-1996
shall additionally comply with the specifications and interchangeability requirements of the applicable corresponding component standards.

Note: See Appendix A for the test to determine "whether a conductive part will become a live part causing electric shock". 1.2.16 Basic insulation basic insulation is insulation added to live parts to provide basic protection against electric shock. Note: Basic insulation does not necessarily include insulation specifically used for operational purposes. 1.2.17 Supplementary insulation: In addition to basic insulation, independent insulation that provides protection against electric shock when basic insulation fails. 1.2.18 Double insulation doubleinsulation insulation consisting of basic insulation and supplementary insulation. 1.2.19 Reinforced insulation reinforcement is a single insulation system applied to live parts that provides a level of protection against electric shock equivalent to double insulation. GB7000.1-1996
Note; "Insulation system\ does not mean that the insulator must be a homogeneous piece. It can be composed of several layers, but it cannot be tested separately like supplementary insulation or basic insulation.| | tt | Accessible conductive parts, if any, are not connected to protective conductors in the fixed wiring of the installation, and in the event of failure of basic insulation, one has to rely on the environment. Note
Class 10 luminaires may either have an insulating enclosure, It can be partially or completely insulated, or it can have a metal shell that is separated from live parts by at least basic insulation. Class 30 luminaires may contain double insulated or reinforced insulated parts. Protection against electric shock in class luminaire luminaires not only relies on basic insulation, but also includes additional safety measures, namely the connection of accessible conductive parts. A protective conductor in the fixed wiring of the installation so that accessible conductive parts are not energized in the event of failure of basic insulation NOTE
1 For luminaires using flexible cables or cords, the protective conductor for this precaution is. Flexible cable or part of a cord. 2 A luminaire designed as Category 1 with a two-core flexible cable or cord, the plug of which is not inserted into a grounded socket-outlet (formerly known as Category 01), then this protection is equivalent to 0 Class. However, the grounding measures of the luminaire in all other aspects shall fully comply with the requirements of Class 1 luminaires. 1.2.23 Class I luminaires may have double insulation or reinforced insulation. Protection against electric shock shall not only rely on basic insulation. Additional safety measures, such as double insulation or reinforced insulation, but no grounding or protection measures dependent on installation conditions
1 Such luminaires may be of one of the following forms: a) Made of durable and strong insulating material. A complete casing of a luminaire that encloses all metal parts, except small parts such as nameplates, screws and rivets, is completely isolated from live parts by insulating materials. Such insulation is at least equivalent to reinforced insulation. Insulated housing type 1 luminaires.
b) Luminaires with a solid all-metal casing, all of which are double insulated, except for those parts where double insulation is obviously not possible. Such luminaires are called metal. Enclosure type luminaires. c) Luminaires having a combination of a) and b) above. 2 The enclosure of an insulated enclosure type 1 luminaire may be part or all of the supplementary insulation or reinforced insulation. 3 If the grounding is to aid starting. Not directly connected to accessible metal parts, the luminaire is still considered a Class 1 luminaire. The lamp holder housing of the light source and the starting strap of the light source are not considered to be accessible metal parts, except those determined to be live parts by the test in Appendix A. 4 If a luminaire with double insulation and/or reinforced insulation has a unified earth terminal or earth contact, the luminaire is of Class I construction. However, a fixed Class I luminaire used for loop installation may have an internal Terminal block used to maintain electrical continuity of a ground conductor that does not terminate within the luminaire. The internal terminal block is isolated from accessible metal by Class 1 insulation. 1.2.24 Class I luminaires rely on the supply voltage for protection against electric shock.
