Recently, a domestic LED lamp was notified by the European Union's Non-Food Hazardous Products Rapid Alert System (RAPEX), which was identified as having a shock hazard and did not meet the requirements of the Low Voltage Directive and the EN60598 standard and was required to be recalled. The specific reason is that the wire diameter of the internal wiring of the lamp is too small. When these lamps are used in series, the internal wiring will overheat, causing insulation damage and the live conductor is exposed. Coincidentally, the wire diameter of the power cord used by an emergency lighting lamp produced by a lighting company in Yuyao did not reach one-fifth of the standard requirements. The test result was a non-conforming product. According to statistics, similar problems have occurred in recent years. The following reasons are worth noting. First, enterprises pay less attention to the selection of wires, and think that they have little effect on the normal operation of lamps and are relatively random. Second, the enterprise is not familiar with the requirements of the relevant standards of the luminaire. It is not clear which type of wire is required for the specific product. It is only necessary to calculate the current according to the power consumed by the luminaire itself to determine the wire specification. Consider the heat resistance of the wire, mechanical strength, the use of lamps in series, outdoor weather resistance and many other factors. Third, due to manufacturing cost considerations, some companies tend to use small-sized wires or even inferior copper wires. These inferior copper wires have high impurity content and poor conductivity, which causes excessive heating of the wires during the operation of the lamps, accelerated aging or breakdown of the insulation, causing short circuits, electric shocks and even fires, and burying safety hazards. To this end, the inspection and quarantine department reminds relevant enterprises that, first of all, enterprises should fully raise their awareness of the importance of the correct selection of wires inside and outside the lamps and strengthen their sense of responsibility. Secondly, it is to understand the specific requirements of the relevant standards of lamps, not only limited to the general requirements of the lamps and lanterns standards, but also familiar with the special requirements of the lamps and lanterns produced by the enterprise and the contents of the wire and cable standards, and to select the valid and valid wire and cable according to the standard requirements. . The third is to strengthen contact with certification bodies and testing laboratories, improve the understanding and application of standards through technical service platforms, and keep abreast of the latest developments in lamp standard revisions to avoid various risks and losses caused by misuse of wires. . disease virus antibody test kit /antibody test kit coronavirus Antibody Test Kit,Hiv Antibody Test Kit,Antibody Rapid Test Kit,Disease Antibody Test Kit Guangzhou HangDeng Tech Co.
