Low voltage directive LVD (2006/95/EC) provides electrical safety for electrical appliances. In March 29, 2014, the European Union's official journal published a new version of the low voltage command, 2014/35/EU, to replace the original low-voltage command 2006/95/EC. The new directive, 2014/35/EU, will take effect on April 20, 2016.
1. scope of application: LVD directive, applicable voltage range of AC 50~1000 V and DC 75~1500 V electrical equipment, computer and peripherals are within the coverage. Notebook computers are rated below 50 AC V and DC 75 V, but they are battery driven products and need to be used with the power supplies, so they are also within the scope of this directive.
2 basic requirements: the directive of integrated security, electrical equipment design and structure security and information security are proposed in accordance with requirements of regulations to prevent dangerous hazard caused by electrical equipment requirements caused by direct action and indirect action, such as contact protection, heat, radiation, mechanical and non mechanical factors, over current and over voltage protection.
The LVD directive emphasizes safety, because not only refers to the hazard caused by electrical equipment with electrical, mechanical and chemical risk also includes all aspects of causes, including the harm of noise and vibration and environmental factors on human health and safety. And on the radiation interference and anti interference EMC requirements in the EMC directive, LVD directive is not in the scope of radiation, mentioned in LVD directive requirements restricted to those directly to the human body and animal home radiation hazards limit requirements.
The basic requirements of LVD command shows in 11 its security objectives, the specific content is as follows:
(1) general conditions
To ensure that electrical equipment is designed in accordance with the right to use, the basic properties of the logo should be on the device or in the accompanying report;
The name and trademark of the manufacturer shall be clearly printed on the electrical equipment or on the packaging;
Design of electrical equipment and components shall ensure that the equipment can be safely and correctly installed and connected;
The design and production of electrical equipment shall ensure that the hazards indicated in the following (2) and (3) points of the protection shall be used and properly maintained if the equipment is in accordance with its design purpose.
(2) to prevent the harm caused by electrical equipment should take measures to ensure that There is enough protection to people and livestock, from electrical contact directly or indirectly caused by physical damage or other hazards (electric shock);
Will not lead to a dangerous temperature, arc or radiation;
People, animals and property are adequately protected against non electrical hazards arising from the use of electrical equipment experience;
Adequate insulation protection shall be provided under foreseeable conditions.
(3) to prevent the harm caused by external factors affecting electrical equipment should take measures to ensure that
Electrical equipment meet the requirements of machinery, so as not to endanger the life, livestock and property;
Electrical equipment can withstand the impact of non mechanical in expected environmental conditions, so as not to endanger the life, livestock and property;
In the case of predictable overloads (overcurrent), electrical equipment does not endanger human, livestock or property
