Model SSP for Prohesion or Conventional Salt Spray Tests
Numerous accelerated corrosion tests may be performed in Q-FOG SSP corrosion tester including Prohesion, ASTM B117 and G85, BS 3900 F4 & F9, DIN 50.021 and ISO 9227. Visit our standards page or see LF-8131 - Partial List of Standards Met by Q-FOG for more information.
The Prohesion test uses fast cycling, rapid temperature changes, a low humidity dry-off cycle and a different corrosive solution to provide a more realistic test. Many researchers have found this test useful for industrial maintenance coatings.
Continuous salt spray exposures are widely specified for testing components and coatings for corrosion resistance. Applications include plated and painted finishes, aerospace and military components, and electrical/electronic systems.
Most of these tests are performed to particular specifications such as ASTM B117 (Salt Spray), and BS 3900 F4. These tests are widely used for relative corrosion testing. They are typically run at an elevated temperature and do not incorporate a dry-off cycle. They require heated, humidified air for the spray.
Model CCT for Corrosion Research and Cyclic Automotive Tests
The Q-FOG model CCT has all the advantages of the model SSP, but adds the flexibility of including 100% humidity.
Today’s automotive corrosion test methods typically call for exposing specimens to a repetitive cycle of salt spray, high humidity, low humidity dry-off, and ambient conditions. These test methods were originally developed as labor intensive manual procedures. The multi-functional Q-FOG CCT corrosion tester is designed to perform these cyclic tests automatically in a single chamber.
Q-FOG model CCT advantages include the elimination of:
- manual moving of test specimens from one chamber to another
- laborious spraying of test specimens
- variability in results from excessive specimen handling
Model CCT units come equipped with a viewing window in the side of the lid and an internal light to allow easy monitoring of the test conditions.
