What is LVD Test ?
Devices operating in the voltage range defined under the low voltage directive (LVD) issued by the European Union must meet the requirements under harmonized standards under this directive.
The relevant type tests in these standards are known as LVD test or tests.
Low Voltage Directive (LVD)
While the directives define only the basic requirements and marking conditions, harmonized standards specially prepared for the product under the directives includes details on descriptions, structural requirements, documentation and tests.
These standards are prepared and published by institutions such as CEN, CENELEC and ETSI as a result of commission studies. These standards also contain health-related content, primarily safety. Electricity powered devices are subject to this directive and are expected to complete the relevant tests positively.
When the standards prepared on product basis are examined, their single content generally includes the following applications. Details and limit values of these applications are also included in the standards:
- Temperature rise
- High voltage insulation tests
- Leakage currents
- Earthing
- Structural requirements
- Creepage and clearances
- Glow wire test
- Verification of protection IP
- Verification of protection IK
- Mechanical test
- Discharge tests
- Single fault tests
- Marking and documentation
CE marking under LVD
The European Union has defined the routes to be followed for CE marking under a total of 8 modules. When we examine the requirements of the modules to which the products are subject, we come across a technical file definition.
Whether or not the notified body requirement is required, the technical files must be prepared completely by the manufacturer. This marking made in accordance with the relevant directive or directives is a legal requirement according to the law numbered 4703 in order to put the products on the market.
In the marking process to be made within the scope of the Lvd directive, an approved establishment is not needed, and the declaration made by the manufacturer is taken as basis.
The technical files of electrical products should include risk analysis, product description, user manuals, electrical diagrams, and sub-component definitions.
In addition to this, the technical file should contain the complete type of test reports, which were made strictly according to the relevant standard.
LVT test laboratories provide manufacturers with a wide range of testing services, especially those of the harmonized standards of LVD, EMC, MDR and MACHINERY directives.
