Whether through contamination during maintenance actions, ingress from degraded seals, or other degradation, the fluid ingress into a connector can cause degradation and impact reliability. To assess this, the electrolytic erosion test measures the propensity of connectors to erode when contaminants are present and the connector is in use.
The test consists of introducing a salt-water contaminant to a connector, mating the connector, then energizing the pins for 40 hours at 60 volts. Upon completion, the contacts are examined under magnification for erosion to the base metal.
Parameters that can be changes for this test include but are not limited to:
- Applied voltage
- Test duration
- Post test assessment technique
