Due to its special surface finish the Fischer Freedom™ Series withstands long-standing exposure to salt fog. Both mated and unmated connectors are exposed to a 5% salt solution at a temperature of 35 degrees Celsius or 95 degrees Fahrenheit. After 1,000 hours, the connectors are removed from their supporting racks and dried. Visual, electrical and mechanical controls are performed after the test. Cosmetic changes may appear over time without impacting mechanical or electrical functionalities.
