Recently, the reporter understands from gansu province quality technology supervision bureau’s website, the second quarter of this year, the province bureau of quality and technical supervision to entrust relevant provincial quality inspection agency for the production (sales) such as the light bulb lamp 12 products quality supervision and inspection.
The selectived examination 52 enterprises in lanzhou city circulation field distribution of 60 batches bulb lamp, 43 companies sell 50 batches of qualified products, percent of pass is 82.7%, product inspection percent of pass is 83.3%, the sample inspection products are market circulation field.
According to the second quarter of 2013 since the ballast fluorescent lamp product quality regular supervision and inspection rules “and the relevant product standards, mainly for logo, prevent to get an electric shock, the input power, mechanical strength, heat resistance, fireproof and flameproof, initial photosynthetic efficiency (flux), power factor and so on eight key indicators for inspection; According to the 2013 lamps and lanterns, regular monitoring and inspection product quality inspection rules “and the relevant product standards, mainly on the structure, mechanical strength, exterior wiring and internal wiring, prevent to get an electric shock, resistance to moisture (waterproof), insulation resistance and dielectric strength, leakage current and the clearance and creepage distance, unthreaded terminal 10 indexes such as the inspection, there are 10 batches of product quality problems. One is the external and internal wiring connection does not accord with a standard to ask.
Standard requirement of connecting wire cross-sectional area for acuity 0.4 cm2, unqualified products in the measured value was 0.3, 0.3 was respectively. Cross-section of the power cord is too low, easy to cause the lamps and lanterns in the power cord fever, such as fire danger; 2 it is part of the product of the initial photosynthetic efficiency (flux) does not accord with a standard to ask.
