| Overall Size (including bath large enough for 2 beakers side by side) |
1 metre long x 0.5 metre deep x 1 metre high |
| Power | single phase power supply (220/240 or 110 Volts AC) |
| Suitable for testing Corrosion Resistance of knives to the following specifications: |
EN 844-1 Clause 6.1 Food Preparation knives EN8442-2 Clause 7.1 Table knives EN8442-4 Clause 7.2 Table knives BS 6813 Clause 5.1 Food Preparation knives BS 5577 Clause 6.1 Table knives |
The equipment consists of a thermostatically controlled water bath (suitable for 60°) into which beakers containing the salt solution can be placed. Above the bath is a special hoist arrangement
Fitted on its own framework made from black hollow section material
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.
