Mandatory national standards for lamps will come into effect on January 1, with category 0 lamps with the lowest safety level gradually withdrawn from the market according to the regulations. On November 4, foshan quality supervision bureau convened nearly 100 lighting enterprises in the city to promote the implementation of this standard.
According to the classification protection against electric shock, lamps and lanterns can be divided into 0, Ⅰ, Ⅱ, Ⅲ, safety worst 0 class of lamps and lanterns, just rely on basic insulation as a protection against electric shock. According to introduction of relevant person in charge of bureau of city quality supervision, the national standard that will be implemented soon "lamps and lanterns part 1: general requirement and test" made clear provision to the general requirement of lamps and lanterns that use electric light source, power supply voltage does not exceed 1000V. Compared with the old standard, the new national standard has a number of major adjustments in the safety requirements, among which the biggest technical difference is the formal deletion of class 0 lamps.
"Due to the variety of lamps and the places where they are used, it is difficult for the identification and restriction of class 0 lamps to take effect in the past. The deletion of class 0 lamps is for safety reasons." National electrical appliances quality inspection center, senior engineer Liu Yuezhan explained Ⅰ the lamps and lanterns, Ⅱ, Ⅲ additional protective measures are taken, even if the insulation protection malfunction as well as provide protection against electric shock. However, class 0 lamps only rely on basic insulation as the protection against electric shock. Once the basic insulation fails, it is easy to produce electric shock hazard.
Current, the bracket lamp that often sees on market, absorb dome light, desk lamp, floor lamp, downlight to wait but move type lamps and lanterns and embedded lamps and lanterns in, 0 kind lamps and lanterns held very big scale. Due to the past market did not pay much attention to the type of electrical protection lamps, many lighting manufacturers are still in the production of relatively simple class 0 lamps. The deletion of category 0 lamps in the new national standards makes these manufacturers face technological transformation.
