New Corrosion Test Cabinets: Worldwide Kesternich Testing Services Now Available

As part of our long standing commitment to ensuring that the services we offer at NiTEC are of the highest quality, as well as consistently meeting the ever expanding needs of our customers, we are now offering specialist Kesternich testing at our metal finishing factory in Chesterfield.

Kesternich testing cabinet for measuring corrosion resistance

Kesternich testing for diffused nickel plating was previously required only twice a year, but now has to be carried out every month. Our new Kesternich testing cabinet will help our customers to meet the standards required of their products with regard to corrosion testing, providing a guarantee that measurements of corrosion resistance are carried out thoroughly.

Corrosion Testing Technology

The Kesternich test chamber at NiTEC is made by VLM, who for many years have been the undisputed technology leader in corrosion testing technology. In addition to providing laboratory technology services, their chambers meet the highest safety standards and create the perfect conditions to carry out accurate and controlled Kesternich testing.

Sulphur Dioxide Testing

Kesternich testing, or sulphur dioxide testing, is commonly used for industrial objects, especially metal objects which are subject to corrosion. Resistance to corrosion is measured in Kesternich cycling, and this method of accelerated corrosion testing is an approved method to perform corrosion tests on metallic components.

To perform a Kesternich test, 2 litres of sulphur dioxide is introduced into a 300 litre test chamber. The dosing of the SO2 gas is controlled during the test, simulating exposure to chemicals that may compromise the surface of a component resulting in corrosion.

The Impact of SO2 in the Atmosphere on Corrosion

Kesternich testing simulates acid rain or industrial chemical exposure to evaluate the relative corrosion resistance of the coating, substrate, or part itself.  Parts or panels are placed inside a specially designed chamber and are exposed to SO2 and humidity before being evaluated for resistance to corrosion.

Worldwide Kesternich Testing  Services

The Kesternich testing service from NiTEC is available to customers worldwide, as samples can be delivered to us from abroad by DHL. To find out more about our Kesternich testing services, please contact us on 0845 224 3571 or email info@nitec-enp.co.uk
