The exposure of automotive sensors, connectors, and actuators to highly abrasive fine dust poses a risk to vehicle reliability. To prevent mechanical wear and premature failure, qualifying components by measuring the actual ingress resistance of their enclosures is essential. The INTEK laboratory provides the technical solution through the Arizona Dust test—a standardized test that certifies the complete tightness of devices, ensuring they achieve the IP6KX protection rating.
The verification procedure takes place inside certified test chambers and involves exposing the sample to a vertical airflow laden with Arizona Test Dust A2 Fine particles, the specifications of which are defined by ISO 12103-1. The operating protocol requires 20 consecutive exposures and allows for thermal stress applications up to 80 °C. During execution, Active Testing keeps the device powered to monitor its functionality in real time. At the end of the cycle, technical inspection confirms the absence of internal contamination in accordance with the strict parameters of ISO 20653:2023.
Subjecting electronic units to IP6KX tightness testing drastically reduces non-conformity risks during the homologation phase. The objective measurement of protection against the clogging of critical openings prevents costs associated with product recalls, ensuring manufacturers can bring reliable, robust components to market that comply with the most stringent international specifications.
