Corrosion Test Equipment

FOR MARTENSITIC STAINLESS STEEL knives, blades and cutting edge devices
Designed and Manufactured by CATRA

Overall Size

2 beaker version

1 beaker version

1 m long x 0.5 m deep x 1m high

0.5m long X0.5m deep x 1m 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°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.
