LVD Tests of Electrical Devices

Low voltage which is above 50 Volt is accepted as dangerous voltage for human body in electric shock. The danger level is slightly lower as the body resistance is higher at high voltage currents. Effects of electric current on animals and humans TSE IEC / TS 60479 series has taken its place in the standards.

Today, almost all of the machines and equipment used in daily life use electrical energy during operation. Electrical energy carries fire and other risks besides impacts. The Low Voltage Directive (LVD), published in European Union countries, relates to the safety of all electrical devices and equipment. For other devices that do not fall within the scope of this regulation, such as medical devices, special electrical devices and equipment used in aircraft, ships or railways, separate legal regulations have been tried to provide electrical safety.

The safety of all devices using electrical energy is verified by electrical tests. These tests are commonly referred to as electrical safety tests, and LVD tests (low voltage tests) are part of these tests. In this context, tests such as protection against access to voltage sections, heating test, leakage current test, electrical resistance test, moisture resistance test, unusual working test, structural test, discharge test, earthing test, insulation test and surface leakage test are performed.

In Turkey, LVD tests are carried out on the basis of the Regulation on Electrical Equipment (2014 / 35 / EU) issued by the Ministry of Science, Industry and Technology (XNUMX / EU). A few standards considered during these tests are:

  • TS EN 60335-1 Safety rules - For household and similar electrical appliances - Section 1: General rules
  • TS EN 60598-1 Lighting fixtures - Part 1: General rules and tests
  • TS EN 60950-1 Information technology devices - Safety - Part 1: General requirements
  • TS EN 60204-1 Safety in machinery - Electrical equipment of machinery - Part 1: General rules
  • TS EN 60601-1 Electrical and medical equipment - Part 1: General requirements for basic safety and performance
