2006/95/EC ）对电器产品的电气安全予以了规定。 The Low Voltage Directive LVD ( 2006/95 / EC ) regulates the electrical safety of electrical products. On March 29, 2014, the official journal of the European Union published a new version of the Low Voltage Directive 2014/35 / EU to replace the original Low Voltage Directive 2006/95 / EC. The new directive 2014/35 / EU will be implemented from April 20, 2016.
1. Scope of application: The LVD directive applies to electrical equipment with AC 50 to 1000 V and DC 75 to 1500 V. Computers and peripherals are covered. Notebook computers have a rated voltage lower than 50 V AC and 75 V DC, but they are battery-powered products and need to be used with power supply units, so they also fall into the scope of this directive.
2. Basic requirements: The directive puts forward compliance requirements for comprehensive safety, design and structural safety, and information safety of electrical equipment, and specifies requirements for prevention of hazards caused by direct and indirect effects of electrical equipment, such as contact protection and overheating. , Radiation, mechanical and non-mechanical factors, over current and over voltage protection, etc.
The safety emphasized by the LVD Directive not only refers to the dangers caused by electrical equipment used in electricity, but also includes the dangers caused by all aspects such as machinery and chemistry, including the harm to human health and safety caused by noise, vibration and environmental factors. The EMC requirements for radiated interference and anti-interference are stated in the EMC Directive, which is not covered by the LVD Directive. The radiation requirements mentioned in the LVD Directive are limited to those that directly cause harm to humans and domestic animals. Claim.
The basic requirements of the LVD instruction are reflected in its 11 security objectives, as shown below:
(1) The general conditions ensure that the electrical equipment can be used correctly according to the design purpose, and the basic performance should be marked on the equipment or on the attached report;
The manufacturer's name and trademark should be clearly printed on the electrical equipment or on the packaging;
The design of electrical equipment and its components should ensure that the equipment can be safely and correctly installed and connected;
The design and production of electrical equipment shall ensure protection against the hazards indicated in points (2) and (3) below, if the equipment is used for its intended purpose and properly maintained.
(2) To prevent hazards caused by electrical equipment, measures should be taken to ensure adequate protection of humans and livestock from physical injury or other hazards (electric shock) caused by direct or indirect electrical contact;
No dangerous temperatures, arcs or radiation will be generated;
Adequate protection of persons, livestock and property from non-electrical hazards resulting from experience with the use of electrical equipment;
Appropriate insulation protection under foreseeable conditions.
(3) To prevent hazards caused by external factors affecting electrical equipment, measures should be taken to ensure that the electrical equipment meets the expected mechanical requirements so as not to endanger people, livestock and property;
Electrical equipment can withstand non-mechanical effects under expected environmental conditions so as not to endanger people, livestock and property;
Under foreseeable overload (overcurrent), electrical equipment will not endanger people, livestock and property
