| The electro technical field is governed by a special directive, the "Low Voltage Directive" (LVD). It was established in 1973 - 20 years before the "New Approach" directives. It is considered the prototype for the concept of the "New Approach" directives. The purpose of the LVD is to ensure safety in the use of electrical equipment used within voltage ratings between 50 and 1000 Volts for alternating current and between 75 and 1500 Volts for direct current. Broadly, it covers consumer goods and equipment designed to operate within those voltage limits, including domestic electrical appliances, hand tools, lighting equipment, electric wiring, cables and piping, and installation equipment. It covers all safety aspects of this equipment, including protection from hazards of mechanical origin. The LVD specifies that the member states of the European Communities
shall take all appropriate measures to ensure that only such electrical
equipment may be put on the market that does neither endanger
the safety of people nor that of domestic animals or property.
This is assumed to be given if: |
|||||||||||||||||||||||||||
| · | the equipment
has been constructed in accordance with good engineering practice
in safety matters |
||||||||||||||||||||||||||
| · | the equipment
has been properly installed and maintained |
||||||||||||||||||||||||||
| · | the equipment
is used for the purpose the equipment was made for. |
||||||||||||||||||||||||||
| These provisions are met if the equipment complies with certain safety requirements recognized in all member states. Without prejudice to any other form of proof, the proof of compliance may be established by reference to harmonized standards which state good engineering practice. The LVD was established before CE Marking was created. CE marking is a reference to the New Approach directives generated in the past years by the European Communities. The adoption of the LVD to today's needs is done by the directive 93/68/EEC. According to the directive 93/68/EEC, the manufacturer or his authorized representative within the EU draws up the Declaration of Conformity and href="http://www.tuv.com/en/affiliates_en.tuv.com.php"xes the CE marking on the product to show conformity with the LVD and its requirements. From the time the product is put on the market, the manufacturer keeps Technical Documentation at the disposal of the relevant authorities for inspection purposes. The report is kept for a period of ten years after the product was put on the market.

|
||||||||||||||||||||||||||
| The technical
documentation must contain details of the design, manufacture
and operation of the electrical equipment in so far as these details
are needed to assess the conformity of the electrical equipment
with the requirements of the directive. |
|||||||||||||||||||||||||||
| · | a general description
of the product |
||||||||||||||||||||||||||
| · | design and manufacture
drawings plus diagrams of components, sub-assemblies, circuits etc. |
||||||||||||||||||||||||||
| · | descriptions and explanations
needed to understand the above mentioned drawings and diagrams plus
the operation of the electrical equipment, |
||||||||||||||||||||||||||
| · | a list of the standards
used, in full or in part, and a description of the solutions employed
to meet the safety aspects of this directive when standards have
not been applied, |
||||||||||||||||||||||||||
| · | the results of design
calculations and of checks carried out, etc., |
||||||||||||||||||||||||||
| · | test reports (in fact,
the test reports which may be available, either established by the
manufacturer or a third party). |
||||||||||||||||||||||||||
| Who must keep the technical documentation and where? The manufacturer or his authorised representative established in the Community must keep this documentation at the disposal of the national Authorities for inspection purposes for at least ten years from the last date of manufacture of the product. The technical documentation may be kept on electronic support provided that it is easily accessible for inspection. Where the manufacturer is not established in the Community and he has no authorised representative in the Community, this obligation is incumbent upon the importer or the person responsible for placing the product on the Community market. |
