The mandatory national standards for lamps and lanterns will be implemented on January 1 next year. The Class 0 lamps with the lowest safety level will gradually withdraw from the city on November 4th. The Foshan Municipal Quality Supervision Bureau convened nearly 100 lamps and lanterns enterprises in the city. Implement this standard.
According to the categories of protection against electric shock, lamps can be classified into Class 0, Class I, Class II, Class III. Among them, Class 0 lamps have the worst safety and rely solely on basic insulation as protection against electric shock. According to the relevant person in charge of the Municipal Quality Supervision Bureau, the national standard "Lamps Part 1: General Requirements and Tests" to be implemented will clearly stipulate the general requirements for lamps using electric light sources and power supply voltages not exceeding 1000V. Compared with the old standard, the new national standard has a number of major adjustments in safety requirements. The biggest technical difference is the official deletion of Class 0 lamps.
Due to the variety of lamps and places of use, the identification and limitation of Class 0 lamps in the past is difficult to take effect. The class 0 lamps are removed for safety reasons. Liu Yuezhan, senior engineer of the National Daily Electrical Quality Inspection Center, explained that Class I, II and III lamps have taken additional protective measures to provide protection against electric shock even if the insulation protection fails. Class 0 lamps rely only on basic insulation as protection against electric shock. Once the basic insulation fails, it is easy to generate electric shock.
At present, among the portable lamps and recessed lamps, such as bracket lights, ceiling lamps, table lamps, floor lamps, downlights, etc., which are often seen on the market, Class 0 lamps account for a large proportion. Since the market has not paid much attention to the anti-electricity protection category of lamps, many lamps and lanterns manufacturers are still mainly based on Class 0 lamps with relatively simple production technology. The removal of Class 0 lamps in the new national standard has made these manufacturers face technological transformation. (Foshan Daily)

Light wires wrapped in a thin plastic skin will quit the life of the citizens. On November 4th, the reporter learned from the lighting standard presentation held by the Foshan Municipal Quality Supervision Bureau that the 0-type lamps that are currently widely used and only one layer of insulation and are not grounded will be discontinued next year, and are expected to be withdrawn in the next year. Shangchang Foshan has more than 70% of the more than 150 lighting companies producing 0 types of lamps. After the cancellation of Class 0 lamps, more than 100 enterprises will stop the production of such lamps.
Class 0 lamps are prone to electric shock
The reporter learned from the meeting that according to the newly released lighting standards, the production of Class 0 lamps will be cancelled from the New Year's Day next year. Although the production of Class I~III lamps is not affected, many inspection indicators have also changed.
It is reported that the lamps for protection against electric shock are classified into categories 0~III. It is popular to understand that Class 0 lamps have only one layer of insulation and the jacks are not grounded. It is easy to get an electric shock when used. The lamps that are hung by a common table lamp and a country house under the roof are all Class 0 lamps. A lighting factory technician told reporters. In addition to a layer of insulation, Class I lamps have other measures to prevent electric shock. The higher the level, the more electric shock can be prevented.
The reporter learned that at present, Class 0 lamps are widely used in most areas of China. The lecturer and the senior engineer of the Guangzhou Weikai Testing Technology Research Center said that Class 0 lamps, once the insulation is broken, are extremely easy to get an electric shock when used.
Light Enterprise: The impact of suspension of production is not big
There are more than 150 lighting manufacturers in Foshan, mainly concentrated in Shunde and Nanhai. Among them, 70% of the enterprises producing 0 types of lamps and lanterns.
The reporter yesterday called Mr. Huang, the representative of the more representative Leike Lighting Company in Foshan Lighting Company, to get a reply. It has already been heard that Class 0 lamps will be discontinued. They have intentionally reduced the production of Class 0 lamps a few months ago. There are not many lamps sold by the company.
Mr. Li, an engineer at an electrical appliance factory, said that canceling the production of Class 0 lamps would not have much impact on the company. Technically, it is only necessary to add a grounding conductor to the Class 0 luminaire, and the safety performance will be greatly improved, and the production will be easier.
The relevant person in charge of the Municipal Quality Supervision Bureau told the reporter that from the date of publication of the new standard, the company will be given a buffer period of one year. Although it is required to suspend production on New Year's Day next year, it is forbidden to circulate in the market but will start from New Year's Day. As far as time is concerned, it should not put too much pressure on the company.
Prediction: Table lamp may add ground wire
A technician said that the cancellation of Class 0 luminaires is essentially safer. The ordinary lamps used now may be rooted in a three-pronged plug, or a layer of skin on a single layer of plastic skin. Nowadays, there are still many electric lights used by users in the country. A wire is pulled out of the light bulb, and the wire is covered with only a thin plastic skin. Excessive temperatures caused by the use of electric lights for too long may ignite surrounding flammable materials (generally wooden roofs); it would be safer to use a layer of insulation to use electricity.
