VW TL 824 66 standard developed by Volkswagen automobile company defines a test method for determining immunity to electrostatic discharge in vehicles. This standard describes the electrostatic discharge test methods and procedures required to evaluate electronic modules for vehicle use.
Electrostatic discharges are one of the most important reasons affecting the quality in electronic applications. In industrial and automotive environments, the system must be protected against electrostatic discharges.
Electronic systems have a variety of potential entry points that cause electrostatic discharge, such as connectors, antennas, buttons, and more. Therefore, it is necessary to use a component that does not affect the signal or power integrity of the system. Electrostatic discharge guards are generally of high efficiency and prevent weakening or damage to integrated circuits after an electrostatic discharge.
The VW TL 824 66 standard is a test standard that specifies electromagnetic immunity requirements for electronic equipment when subjected to electrostatic discharge from the human body or metal objects. Electrostatic discharge immunity testing is performed to determine whether a product complies with the electrostatic discharge protection area and procedures. Electrostatic discharge can be transferred through air or contact.
In the automotive industry, it is essential to keep all internal wiring and circuitry at least 5 cm from any slots, seams or openings in the enclosure to prevent unwanted electrostatic discharge from occurring. Using a metal or metallized enclosure, only 20 to 40 dB of shielding is required to achieve good electrostatic discharge immunity.
While not always feasible, prioritizing electrostatic discharge immunity and protection in the design is crucial during product development. By the end of the product development cycle, fundamental design elements, including grounding scheme, chassis design, printed circuit board layouts, software/firmware architecture, and manufacturing requirements, must be robust. Overcoming these challenges often requires a system-level approach.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides test services for the determination of immunity to electrostatic discharge in vehicles, within the scope of Volkswagen VW TL 824 66 standard, with its trained and expert staff and advanced technological equipment.
