The equipment consists of a thermostatically controlled water bath (suitable for 60°C) into which beakers containing the salt solution can be placed. Above the bath is a special hoist arrangement giving a constant raise and lower rate of 3 cycles/ minute.
Fitted on its own framework made from black hollow section steel
A plastic rack designed to hold and separate the test pieces, generally shown in EN 8442-2, can be coupled to each hoist cable and is driven in an up and down cycle to intermittently immerse the work in the salt solution at the required rate of 3 times per minute.
The corrosion test is designed to stimulate the cumulative corrosion conditions a knife would experience in typically 2 or 3 years. It will detect overheating of blades caused by grinding processes in manufacture.
