Electrostatic Discharge Tests

Immunity tests for electrical or electronic systems or devices include electrostatic discharge tests. Electrostatic discharge is a very fast electric flow (ESD) that occurs when two objects with different electrical charges come into contact or approach each other. In the meantime, objects with isolated or polarized electrical charges can also be the cause of electrostatic discharge.

It is a static charge that causes an electrostatic discharge. In fact, the electric charge at a certain pole is potentially present in objects. So it's stable. However, when this object comes into contact with another object carrying electricity at different poles, or when it touches this object, the electrical charge waiting in the static state begins to flow from one object to another object. This is called electric discharge (discharge).

If the potential difference between the static-charged object and the other object is too large, the discharge may also occur without contact. Because the medium between the objects (this medium is usually air) loses its insulation and becomes conductive.

Friction is the most common condition in the formation of static electricity. Static charge of the comb when combing hair is the simplest example. Or cracking felt when removing the sweater is also an example of static electricity.

Static electricity encountered in daily life is not a threat to human health. However, it requires precautions for sensitive electronic devices. So yeffective in laboratories electrostatic discharge tests are performed.

our organization also conducts electrostatic discharge tests within the scope of EMC tests. in accordance with the relevant legal regulations, standards and test methods published by domestic and foreign organizations. A few standards considered in these studies are:

  • Electromagnetic compatibility (EMC) - Part 61000-4: Immunity to electrostatic discharge (From air: 2-4 kV, Contact: 2-2 kV)
  • 61340-3-1 Electrostatic - Part 3-1: Methods for the simulation of electrostatic effects - Human body model (hbm) electrostatic discharge test waveforms

Our institution, from the ÖSAS Accreditation Institution, It is accredited according to TS EN ISO / IEC 17025 standard and the tests, measurement, analysis, inspection and inspection procedures and reports are accepted as valid in private and official audits.
