What is LVD certification?

LVD certification is the LVD low voltage directive under CE certification. It was originally formulated in 1973, namely the 73/23/EEC directive, which has undergone several revisions and was updated in 2006 to 2006/95/EC according to the EU's legal preparation rules. , but the substance remains unchanged. In March 2014, the European Union announced a new version of the Low Voltage Directive 2014/35/EU, which replaced the original 2006/95/EC Directive. The new directive came into effect on April 20, 2016.

The goal of the LVD Directive is to ensure that electrical products sold and manufactured within the European Union are safe for consumers when they work properly or when they fail.

"Low Voltage": The LVD Directive defines a "low voltage" product as electrical equipment with a rated voltage of 50-1000 volts AC or 75-1500 volts DC.

Note: Electrical products with AC voltage below 50 volts or DC voltage below 75 volts are governed by the EU General Product Safety Directive (2001/95/EC) and are not within the scope of the Low Voltage Directive. Certain commodities such as electrical products in explosive atmospheres, radiological and medical equipment, household plugs and sockets are also not covered by the Low Voltage Directive.

The main changes in 2014/35/EU compared to 2006/95/EC are

1. Ensuring easier market access and a higher level of security.

2. Clarified the responsibilities of manufacturers, importers and distributors.

3. Strengthen the traceability and supervision requirements for defective products.

Requirements of the LVD Directive

The requirements of the LVD directive can be summarized as 10 safety objectives under 3 conditions

1. Safety requirements under general conditions

(1) To ensure that the electrical equipment can be used correctly according to the design purpose, and the basic performance should be identified on the equipment or on the accompanying report.

(2) The design of electrical equipment and its components shall ensure that they can be installed and connected safely and correctly.

(3) If the equipment is used in accordance with its design purpose and properly maintained, its design and production shall ensure that it can meet the hazard protection requirements in the following two situations.

2. Safety protection requirements when the equipment itself generates risks

(1) Adequate protection of persons and livestock from physical injury or other hazards caused by direct or indirect electrical contact.

(2) No dangerous temperature, arcing or radiation will be generated.

(3) Adequate protection of persons, livestock and property from common non-electrical hazards (such as fire) caused by electrical equipment.

(4) Appropriate insulation protection under foreseeable conditions.

3. Safety protection requirements for equipment under external influence

(1) Meet the expected mechanical performance requirements and will not endanger people, livestock and property.

(2) Resistant to non-mechanical influences under expected environmental conditions so as not to endanger persons, livestock and property.

(3) Not endangering persons, livestock and property under foreseeable overloading (overloading).

Hint for coping: Following harmonised standards is an effective way to deal with the LVD directive.

"Harmonized standards" are a class of technical specifications with legal effect, which are formulated by European standards organizations such as CEN (European Committee for Standardization) based on EU requirements, and are regularly published in the Official Journal of the European Union. Many harmonized standards are revised with reference to the IEC standards of the International Electrotechnical Commission. For example, the applicable harmonized standard for USB chargers, EN62368, is transformed from IEC62368.

Chapter 3, Section 12 of the LVD Directive clarifies that, as the primary basis for conformity assessment, electrical products that meet the harmonized standards will be directly presumed to meet the safety objectives of the Low Voltage Directive. Products that have not issued harmonized standards need to be evaluated with reference to IEC standards or member state standards according to corresponding procedures.

Applying for CE-LVD certification generally follows the following process

1. Submit application materials to Dezewei Testing and Certification Agency, such as application documents containing basic information of applicants and products.

2. Submit the product instruction manual and product technical documents (such as circuit design diagram, component list and component certification information, etc.).

3. The Dezewei organization conducts product testing according to relevant standards, and issues a test report after the product has passed the test.

4. Dezewei agency issues CE-LVD certificate according to relevant data and test report.

Products that have obtained the CE-LVD certificate need to maintain the consistency of product safety, and cannot arbitrarily change the product structure, function, and key components, and save the corresponding technical data for supervision and inspection.
