TWI Cyclic Immersion Testing

Please select a valid form ×

This facility is for corrosion testing of samples under simulated splash zone conditions. The samples are mounted and then lowered into a temperature controlled aqueous solution (seawater, acids, alkalis etc.) for a set duration (e.g. 10 minutes) and then withdrawn and allowed to dry for a set duration (e.g. 50 minutes). This cycles automatically and can be run for a period of several months with up to 100 cycles/day. The facility is suitable for both coated and uncoated specimens, and up to eight specimens can be run simultaneously
