With the operational facilities in Hassloch/Main, Zeros sets
new benchmarks for destructive testing of materials.
Salt Spray Testing
Salt Spray Testing is the most common experimental arrangement for an accelerated corrosion test. For that, the components are sprayed with a 5 percent sodium chloride solution over a specific time slice (up to 24 hours) and with defined boundary parameters. This test prevails as testing method for quality control of coatings within the industry. The chemical and physical finishes as well as the organic and metallic coatings are to be examined.
Sunlight accelerates the ageing of materials. Standardised Xenon lamps, whose emission spectrum and light emission are similar to that of the sun, simulate this effect and turn out to be a valuable tool for life-time monitoring. Via the Xenon testing, the ageing of the material can be forecasted quite accurately – when considering other environmental factors such as humidity and temperature.
At the climatic testing, components are tested under different environmental conditions and in defined time intervals. Thus, it is possible to test their foreseeable durability relating to the application site and the prevailing environmental conditions – e.g. a high humidity, much rain, high or low temperatures or temperature fluctuations as well as combinations of humidity and temperature.
Condensed Water Climate Testing
The condensed water climate testing describes a testing method proving the corrosion of metallic components. During this process which takes place in a special testing room, the components are exposed to a defined amount of distilled water at a fixed temperature within a given time span used for corrosion tracking.
Heading “Acid Rain”: With the help of the oxygen test, the influence of precipitations with a low pH-value on the materials can be proved. The components are stored in a special testing room with a defined amount of distilled water and a fixed temperature. Subsequently, sulphur dioxide is added and checks it for corrosion effects within a given time interval. In a sense, the Oxygen testing constitutes an extension of the condensed water climate testing where oxygen is added to the analogous test implementation.
