LOW VOLTAGE (lvd) DIRECTIVE, RELATED to EC 2014/35/EU.
The Low Voltage (LVD) Directive EC: 2014/35/EU provides a high level of protection for European citizens within certain voltage limits and applies to the European market and elsewhere in the world.
Regarding the low voltage directive (LVD) LVD it covers health and safety risks in electrical equipment, including input or output voltage.
- 50 and 1000 V for alternating current.
- 75 and 1500 V for direct current.
- Applicable to a wide range of electrical equipment for both user and professional use.
- LVD devices that require testing are listed below.
Household appliances such as:
* Cable.
* The source.
* Laser equipment.
* Specific components, eg: fuses.
EU legislation in the electrical sector is important to ensure that the health and safety requirements for products placed on the market are the same across Europe.
The General Product Safety Directive (2001/95/EC) covers consumer goods with voltages below 50V for alternating current or for direct current below 75V. It is intended to ensure that only products safe consumer products sold in the EU.
The Low Voltage Directive (LVD), adopted in 1973, was an important step in this direction. 1990 and later CE Marking was a condition for free movement within the European Union (EU) market.
CE is a certification of the conformity of products manufactured to the EU single market. A product bearing CE is also entitled to free movement within the EU market. What brings the product to CE are new accessibility reports backed by standards. Penalties for CE marking on a nonconforming product can result in removal of the product from the market.
During this period, especially as the harmonization process with the European Union accelerates. For this reason, companies that manufacture machinery and electronics already know about LVD tests. It is not possible for companies to place their products on the European market without confirming that they are safe, not in compliance with the LVD directive.
Your products must be certified eligible to move freely in the single market of the European Union. Due to the CE Marking certificate, machinery and electronics manufacturing companies are required to perform LVD tests.
Especially in the Saudi Arabia market, it is not possible for an enterprise to obtain a SASO Certificate without its CE certificate certified by SASO (Low Voltage Directive-LVD) tests. Tests (Low Voltage Directive-LVD) are carried out after the appropriate test report provides the enterprise CE certificate.
Due to its different characteristics, the LVD test is carried out on the grounding rules for both high-voltage current installations and low-voltage electrical installations, and the grounding tests of data processing equipment and the media.
With the LVD test and the test report obtained from an accredited institution, the exportation of Saudi Arabia and other European Union or Middle Eastern countries will be facilitated, especially in the case of obtaining a Certificate SASO in Vietnam, exporting companies will have CE certificate along with SASO certificate.
In the low voltage directive, not only the risks arising from electrical faults are considered, but all the risks that can arise from chemical, mechanical and other problems in the equipment. electricity are considered.
The LVD directive also looks at health issues.
Noise, acoustics, ergonomics issues are covered.
Electrical equipment may reduce the performance of other devices because they generate electromagnetic waves in the environment in which they operate, or they may be affected by electromagnetic noise generated by other devices.
Many electrical equipment is also protected by the EMC Directive. In this case, both the LVD and EMC directives are obligated to comply.
It does not require notified bodies to assess whether LVD products placed on the market comply with applicable EU law. The manufacturer alone is responsible for its decision by implementing conformity assessment procedures.
