LVD is the Low Voltage Directive. Directive 73/23/EEC Council Directive 73/23/EEC of 19 February 1973 on the harmonization of laws of Member States related to electrical design for within certain voltage limits LVD Low Voltage Directive 2014/35/EU, the goal of LVD is to ensure the safety of low voltage equipment in use. The instruction applies to electrical products with voltages ranging from 50V to 1000V and 75V to 1500V. The instruction contains all safety rules for the equipment, including protection against mechanical hazards. The design and structure of the equipment shall ensure that there is no danger when it is used in normal working conditions or in failure conditions according to its intended use, especially for the following hazards: (1) Electric Shock; (2) Energy hazard; (3) Fire; (4) Mechanic and heat hazard; (5) Radiation hazard; (6) Chemical Hazard. Safety test parts and components required by safety regulations include: flexible cables and cords, plug, socket-outlet, coupler, connector, AC Inlet, SOCKET, X/Y capacitor, fuse, switch, thermostat, tuning. Dimmer, timer, converter, motor, Speaking, ballast, relay, lamp holder and fuse-holder. Test Items: Input test power test Heating test temperature rise test Humidity test humidity test Glow-wire test hot wire test status test Over Load test overload test Leakage current measurements leakage current test Electric Strength test voltage withstand test Earth continuity anchorage test ground resistance test Cord test power cord tension test Stability test Plug torque test plug torque test Impact test impulse test Capacitor discharge test at plug plug discharge test Fault conditions test components damage test Working voltage measurement working voltage test Motor lock-rotor test motor block test Low and high temperature test Tumbling test drum drop test I Nsulation resistance test insulating resistance test Ball pressure test ball pressure test Screw Torque test screw torsion test Needle flame test needle flame test sample requires 1 main test (series test) model to prepare 2-4 complete samples/model; 2 if special tools are needed for assembly, special tools should be provided at random; 3 if products need normal work under special loads; For example, samples should be sent together with the load to enable the product to work normally; 4. For products that need accessories (controller, connection cable, software, etc.) to work normally, the product should be connected well so that the product can work normally; 5. For products that need chargers, chargers should be provided (chargers need to be marked on the product without testing); 6. For transformers and other products, there is a need for filling and sealing. Samples of the required products, SEALED and UNSEALED should be provided separately. According to the requirements of the testing company, provide some important parts or parts not assembled, such as thermal link, rheostat or resistance, circuit breaker. Technical information requires that the CE system of LVD is similar to EMC directives. All products within the scope of application must have CE logo, and must have a compliance statement signed by the manufacturer's representative or importer. Simple self-declaration is not enough to determine that the product is safe ("safety" is defined as not causing death, injury or financial damage to people or livestock). For this reason, LVD declarations need the support of technical documentation files to prove. Technical certification documents shall include: 1. General description of machine equipment 2. Conceptual design and manufacturing drawings 3. Description and description necessary to understand these drawings 4. Listing all or part of applicable standards and describing countermeasures adopted to meet instructional safety viewpoints 5. Estimation results of design, inspection of execution process 6. Test report items 1-5 above information; Name plate 7 list of key components (see Schedule 2, Samples of Parts List) including manufacturer's name, product model and technical parameters (rated current, voltage, power, flame retardant grade, etc.) Copies of valid safety certificates for key components. Product conformity certification can be used to prove that your product meets the low voltage instructions in three ways: (1) adopting the standards negotiated by the European Community; (2) adopting the standards of the manufacturer's own country if there is no negotiation standard for the product; (3) directly adopting LVD. In this case, it is suggested to consult the authoritative national certification authority. CE logo is the self-declaration that the manufacturer's products meet the requirements of the corresponding EU directives, including Low Voltage Directive (LVD), Electromagnetic Compatibility Directive (EMC) and so on. In order to clearly show that the product meets its low voltage instructions, the CE logo must be marked on the product. If CE logo can't be labeled on the product, it can also be labeled on the product packaging and user's manual.
