- The shell material of lamps needs to have certain fire - resistant properties. Since lamps may generate heat during use, if the shell material is flammable, it is likely to cause a fire. Russia stipulates that the combustion grade of the lamp shell material must meet the corresponding standards. For example, under a specific fire source test, the burning speed of the shell material cannot be too fast, and it cannot produce excessive toxic smoke.
With the increasing emphasis on energy conservation and environmental protection, Russia has also put forward requirements for the energy efficiency of lamps.
