Low Voltage
Low Voltage Directive
Low Voltage Directive (Low Voltage Directive, 2006/95/EC) formulated in 1973, the directive for the new program (New Approach) to develop the first 20 years, and is considered the predecessor of the new program concept.
The goal of the Low Voltage Directive to ensure the security of low-voltage equipment in use.
Electrical equipment in low-voltage equipment is defined between 50-1000 volts rated voltage alternating current, DC 75 to 1500 volts. Broadly speaking, the low-voltage equipment includes equipment, consumer products and is designed to operate in this voltage range. Includes appliances, hand tools, lighting equipment, wires, cables and pipelines, and wiring devices, etc.. This directive contains all the safety rules of this equipment, including the dangers posed by the protection due to mechanical reasons.
LVD must specify the EU Member States to adopt appropriate methods, to ensure that electrical equipment sold in the domestic market will not endanger the safety of the people, it will not endanger domestic animals or property, and therefore must be done:
Equipment must be in accordance with the safety rules of good design.
The device must correctly install and maintain.
The equipment must be used according to the design purposes.
If the device meets specific safety requirements for all Member States recognized, that is to comply with these terms and conditions. Does not affect the other forms that may be made by reference to the provisions of good design standards together to prove their compliance. Low Voltage Directive drawn up earlier in the CE marking the establishment of CE marking is a new program of recent years, was drafted by the EU directive. Directive 93/68/EEC modified Low Voltage Directive to meet modern needs.
According to Directive 93/68/EEC, the manufacturer or the authorized representative within the European Union to prepare a Declaration of Conformity, additional CE marking on the product labeling comply with the Low Voltage Directive and the relevant provisions.
Products to market, manufacturers technical documents must be retained for 10 years for the relevant units for test purposes, the technical documents can be stored electronically, but the premise is likely to be tested. If the manufacturers in the EU there is no base and no authorized representative, this responsibility belongs to import vendor or person in charge of sales in the EU market.
Declared by the sexual content (refer to instructions Appendix 3 (B))
This declaration must include:
Authorized representative name and address of the manufacturer or the EU.
Description of electrical equipment.
Collaborative standard reference.
When necessary, must contain a detailed description of the reference file, according to the manufacturer or its authorized representative within the EU declared that it complies.
Attorney identity of the signer.
Products (for the first time) the last two digits of the year the CE marking.
Declaration of Conformity must be written to at least one official EU language.
Technical contents of the file
The technical documentation must contain detailed data for the design, manufacture and operation of electrical equipment to evaluate the electrical equipment complies with Directive requirements. Therefore, the file must contain:
A general description of the product.
Design and manufacture of maps, and diagrams of components, sub-components, lines, etc..
Explanation of the foregoing drawings and illustrations, as well as documentation of the operation of this electrical equipment.
All or part of the list of criteria, and the solution has not yet provided in the standard part to meet the safety requirements.
Design calculations and the results of the inspection work.
Test Report (proposed by the manufacturer or a third unit test reports).
The manufacturer shall be necessary to ensure that the manufacturing process to meet the technical file referred to the contents of the file should be clearly prove that the products in the design point of view, is safe, but also to determine in the manufacturing process has been consistent.
Establish better safety design method is in line with the harmonized standards listed to the test report as evidence, to reconcile the standards will be regularly published in EC Official Gazette (Official Journal), the use of recognized files (such as EN specifications) can be determined to prepare the file to consider the best information in the industrial field, rather than just their own experience.
In any case, this declaration must consider the the LVD necessary safety norms, and this specification may be beyond the requirements of the harmonized standards. Generally speaking, if the product is clearly in the specification within the scope of EN standards, the EN standard is sufficient.
In order to ensure the continuity of matching, manufacturing, quality systems have to assess the safety of the corresponding parameter. First, each sample was made off the assembly line testing prior to shipment (including grounding continuity, resistance to dielectric strength, insulation resistance), and secondly, to be able to collect from the test results related to product safety critical components (Critical components and materials) and materials (such as fuses, isolation transformers, flammable plastic) according to EN standard test can identify the key components.
