COUNCIL DIRECTIVE 73/23/EEC of 19 February 1973 on the harmonization of the laws of Member States relating to Electrical Equipment designed for use within certain voltage limits.
This directive has been amended by the following Council Directives:
1. 92/59/EEC of 29 June 1992 (General Product Safety);
2. 93/68/EEC of 22 July 1993 (CE Marking directive).


1. Background

The Low Voltage Directive (LVD) was introduced at a time when directives contained detailed technical annexes which were intended to supersede national laws. The LVD set out the essential protection requirements, with the relevant technical details being defined by standards-making organizations. This subsequently paved the way for what were to be known as the New Approach Directives.

2. Scope
2.1 The "Electrical Equipment" means any equipment designed for use with a voltage rating of between 50 and 1000 V for alternating current (A.C.) and between 75 and 1500 V for direct current (D.C.). Therefore, this Directive is called often "Low Voltage Directive" which applies to the vast majority of electrical equipment in everyday use. The Electrical Equipment may be placed on the market only if it does not endanger the safety of persons, domestic animals or property. There are 11 principal elements of the safety objectives listed in Annex I.
2.2 The Low Voltage Directive was the first directive to reference standards, and equipment which complies with harmonised safety standards drawn up by common agreement is deemed to comply. Where harmonised standards are not available, international standards which have been agreed to may be used.
2.3 The Low Voltage Directive has been in existence for over twenty years and, in conjunction with the CE Marking Directive 93/68/EEC which amended it as and from 1st January 1995, note should be taken of some of its main features.
(a) The Low Voltage Directive is not designed to impose safety standards. Its primary purpose is to ensure free trade through the removal of technical barriers.
(b) Conformity with standards is not compulsory, but it can be used as one means to demonstrate compliance with the safety principles enshrined in the directive.
(c) The Low Voltage Directive covers other aspects of safety, including mechanical aspects.
(d) There are some items that are excluded from the Low Voltage Directives and those are listed in Annex II of the directive.
3. Demonstrating Conformity
3.1 From a manufacturer's perspective a key element of the directive is to be found in article 10, which relates to proof of conformity. The Low Voltage Directive defines three means whereby such conformity can be demonstrated; manufacturers declaration, certificates and notified body marks.
3.2 While the manufacturer's declaration is in itself sufficient to provide an "a priori" presumption of conformity of the equipment to the directive (the equipment is deemed to comply unless the importing country can prove otherwise), he must be entirely satisfied that he is correct in this regard.
3.3 Today, when manufacturers are faced with highly competitive markets, shortening product life cycles and continuing economic pressures, they are turning to independent certification agencies to provide the confidence and market advantage that is vital to their business needs. The certification agencies assist by issuing certificates in a recognized format, or by authorizing the use of a notified certification mark.

These mechanisms for certification do not exist in isolation, as reciprocal recognition arrangements are in place between National Certification Bodies at a number of levels.

3.4 The IECEE scheme for the mutual recognition of test reports, and the CENELEC Certification Agreement (CCA) are implemented by many certification agencies.
3.5

On the 1st January 1995, the Amending CE Marking Directive 93/68/EEC came into force. Its purpose, as far as the LVD is concerned, is to modify the conformity assessment and marking provisions so that the LVD can be fully integrated into the new approach/global approach philosophy. (See Articles 13-15 of 93/68/EEC).

From the 1st January 1995 until 31st December 1996 a transitional arrangement applies in that products may be placed on the market if they comply with the marking requirements in force before 1st January 1995. Alternatively, manufacturers may follow the provisions of the Amending Directive and apply the CE Marking, making sure that it is clearly stated that the Marking is evidence of compliance under the LVD. This will permit free circulation, avoiding difficulties with national administrations.

From 1st January 1997, application of the CE Marking will indicate that the equipment complies with the requirements of all relevant directives.

 
ANNEX I
11 PRINCIPAL ELEMENTS OF THE SAFETY OBJECTIVES

1. General conditions
a) The essential characteristics, the recognition and observance of which will ensure that electrical equipment will be used safely and in applications for which it was made, shall be marked on the equipment, or, if this is not possible, on an accompanying notice.
b) The manufacturers or brand name or trade mark should be clearly printed on the electrical equipment or, where that is not possible, on the packaging.
c) The electrical equipment, together with its component parts should be made in such a way as to ensure that it can be safely and properly assembled and connected.
d) The electrical equipment should be so designed and manufactured as to ensure that protection against the hazards set out in points 2 and 3 of this Annex is assured providing that the equipment is used in applications for which it was made and is adequately maintained.

2. Protection against hazards arising from the electrical equipment
Measures of a technical nature should be prescribed in accordance with point 1, in order to ensure:
a) that persons and domestic animals are adequately protected against danger of physical injury or other harm which might be caused by electrical contact direct or indirect;
b) that temperatures, arcs or radiation which would cause a danger, are not produced;
c) that persons, domestic animals and property are adequately protected against non-electrical dangers caused by the electrical equipment which are revealed by experience;
d) that the insulation must be suitable for foreseeable conditions.

3. Protection against hazards which may be caused by external influences on the electrical equipment
Technical measures are to be laid down in accordance with point 1, in order to ensure:
a) that the electrical equipment meets the expected mechanical requirements in such a way that persons, domestic animals and property are not endangered;
b) that the electrical equipment shall be resistant to non-mechanical influences in expected environmental conditions, in such a way that persons, domestic animals and property are not endangered;
c) that the electrical equipment shall not endanger persons, domestic animals and property in foreseeable conditions of overload.

ANNEX II
EQUIPMENT AND PHENOMENA OUTSIDE THE SCOPE OF THE DIRECTIVE
  1. Electrical equipment for use in an explosive atmosphere
  2. Electrical equipment for radiology and medical purposes
  3. Electrical parts for goods and passenger lifts
  4. Electricity meters
  5. Plugs and socket outlets for domestic use
  6. Electric fence controllers
  7. Radio-electrical interference
  8. Specialized electrical equipment, for use on ships, aircraft or railways, which complies with the safety provisions drawn up by international bodies in which the Member States participate.
