A test that allows certification of the suitability of products entering free circulation in the European Union is called an LVD test. It is also made to products such as white goods and machinery that carry CE certificate. It stands for Low Voltage Directive and consists of a number of tests such as high voltage test, leakage current combustion property and ground line continuity. It is not possible to issue a certificate of competence to devices that fail any or more of the tests performed by engineers in a laboratory environment. The Low Voltage Directive provides a high level of protection for electrical equipment within the specified voltage limits.
Covers Security Risks
Input or output voltage electrical equipment for working with Low Voltage Directive covering health and safety risks; 50V 75V to 1500V DC and 1000V for alternating current and applies to both consumer and professional use in various electrical devices. Among the devices that are required to perform LVD testing are cables, power supplies, household appliances, laser equipment, certain components, fuses, EU legislation products released in the electricity sector. A general Product Safety Directive covering voltage below 50V for alternating current and consumer goods or direct current below 75V is required.
Essential to the EU
The low voltage decree was adopted in 1973 and became a condition for free movement within the European Union market after 1990. The Low Voltage Directive is mandatory for all products bearing CE certification, which determines the product's compatibility with the EU Common Market. CE mark cannot be struck on a product that does not meet the required requirements. If hit, the product is collected or removed from the market. Companies that produce white goods and machinery are aware of LVD testing in their activities in our country during the European Union compliance process. Companies can not put their products on the market without proving that they are safe through tests.
CE certification after testing
Grounding rules for both high-voltage electrical power plants and low-voltage electrical plants, tests for grounding information processing and communication equipment are performed. LVD testing is performed by an agreed organization. CE certificate is obtained with the report received from its establishment. In the test, not only the risks arising from electrical problems, but also all risks arising from chemical, mechanical or different problems in the electrical device are taken into account. Health is also considered in the Low Voltage Directive. Noise, sound and ergonomic positions are indicated.
LVD tests performed
Electrical devices produce electromagnetic waves when they work, and therefore they can disrupt the performance of other devices or be affected by the electromagnetic noise produced by these devices. At the same time, electrical devices covered by the EMC directive are required to comply with both the lvd and EMC directive. Approved organizations are not needed to assess whether products released for the Low Voltage Directive comply with European Union legislation. It is the manufacturer's responsibility to carry out and determine conformity assessment procedures. The LVD test performed can be sorted as follows;
- Leakage current tests
- Warm-up tests
- Protection tests against access to stretched sections
- Earth line continuity tests
- Electrical resistance tests
- Moisture resistance tests
- Out-of-the-ordinary work tests
- Structural tests
- Discharge tests
- Tensile test
- Grounding
- Isolation
- Ball pressure
- Blushing wire
- Protection against superficial leakage
- High voltage
- Combustion Test
- Physical strength
- Water testing
- IP dust test
- CE and SASO certificates
Products with CE certification provide ease of export in Saudi Arabia, especially in the European Union and Middle East countries. SASO certification is also mandatory for products in the Saudi Arabian market. In order to obtain this document, it is necessary to obtain the CE report. Saso certification is also given to products that have passed the tests.
