Electrical Safety Tests

The amount of electric charge per unit time passing through a conductor is called electric current. The unit of electric current is Amperes. Current occurs when electrons flow from the positive pole to the negative pole. In order to generate an amperage current, 6,25 x 10 can be generated within one second at any point on the conductor.18 electron must go through.

Electric current is essentially two types: direct current (DC) and alternating current (AC). In direct current, the direction and intensity of the electric current is always constant. It is not time dependent. In the case of alternating current, the direction and intensity of the electric current changes with time.

The physiological effects of the electric current on the human body depending on the intensity can be explained as follows:

  • Under 0.01 mA it is not felt much. Only a tickling sensation occurs in the fingers
  • The hand between 1-5 mA is felt, hand and arm movements become difficult
  • Between 5 and 15 mA, cramps occur in the hand, blood pressure rises and the affected body can be left.
  • Between 15-25 mA, contractions in the body increase, there is no effect on the heart, but the affected body cannot be left.
  • The current between 25-80 mA is intense, the heart starts to beat irregularly, breathing becomes difficult, but can be tolerated
  • Rhythm disorders occur between 80-100 mA, loss of consciousness

In order to ensure safety in the electrical installation, it must be installed, maintained and operated by qualified electricians depending on the type and capacity of the installation. The electrical installation must be installed in accordance with the operating conditions and in a way that will not harm the safety of people and property.

All parts of any electrical installation must be arranged in such a way that, regardless of the activities of the enterprise, the short-circuit current shall be cut off, causing no danger to persons and the installation shall not be damaged.

In general, the longer the exposure time to electric current, the greater the effect it has on the body. In the event of exposure to low voltage, the body is generally shocked and the heart rhythm deteriorates. In case of exposure to high voltage, severe burns occur on the body.

The Low Voltage Directive 2006 / 95 / EC issued by the European Union regulates the safety principles of electrical appliances. Based on this directive, the Low Voltage Regulation (2006 / 95 / AT) has been issued in our country by the Ministry of Industry and Trade. Electric vehicles covered by this regulation are:

·         Electric vehicles used in explosive environments

·         Electrical tools used in radiology and medicine

·         Electrical parts of elevators for the transport of goods or people

·         Plugs and sockets used in residential buildings

·         Electrical measuring instruments and electrical control devices

·         Special electrical equipment used in ships, airplanes or railways in accordance with the safety principles determined by international organizations

The aforementioned regulation applies to all types of electric vehicles and equipment with the following characteristics:

  • Using alternating current between 50 and 1000 volts, or
  • Using direct current between 75 and 1500 volts

Like many test and inspection organizations, our organization provides a range of measurement, testing, analysis, inspection and control services within the scope of electrical safety testing services. The main services provided within this scope are:


  • LVD low voltage test
  • EMC electromagnetic compatibility test
  • IP testing (ingress protection testing)
