CYCLIC CORROSION TEST (CCT)

Cyclic corrosion tests are a way of recreating / accelerating a variety of corrosive climates inside the same equipment (salt spray, condensation water atmosphere, air drying and controlled humidity). It is a very useful test to predict the life expectancy of materials and components and to evaluate in a comparative way different anticorrosive protection coatings.

CLIMATE TEST

The aim of the climate tests is to reproduce in a laboratory, the climatic conditions of temperature and humidity, both normal and extreme, to which materials, coatings, parts, … can be subjected, in order to determine the behavior / resistance of these.

NEUTRAL SALT SPRAY TEST

Salt spray tests are especially useful for detecting pore-type discontinuities or other defaults of some coatings, metallic, organic, anodic oxide or conversion layers.

The neutral salt spray test is the test method in which a sodium chloride solution of defined characteristics is sprayed in a controlled environment.

It applies particularly to metals and their alloys, metal coatings (anodic and cathode), conversion layers, anodic oxide coatings and organic coatings applied to metallic materials.

ACETIC ACID SALT SPRAY / COPPER ACCELERATE ACETIC ACID SALT SPRAY (AASS/CASS)

The acetic acid salt spray test is the test method in which a sodium chloride solution of defined characteristics, with the addition of glacial acetic acid, is sprayed in a controlled environment.

The copper accelerate acetic salt spray test is the test method in which a sodium chloride solution of defined characteristics, with the addition of copper chloride and glacial acetic acid, is sprayed in a controlled environment.

They are especially useful for testing decorative coatings of copper + nickel + chrome, or nickel + chrome, as well as anodic coatings applied on aluminum.

KESTERNICH

The sulfur dioxide test with humidity condensation consists of the action of a humid air containing sulfur dioxide that rapidly produces an easily detectable corrosion on numerous metals and according to the results that look like the corrosion that occurs in industrial environments.

HUMIDITY

The Corrosion Test in Saturated Humid Atmospheres, consists of the action of hot saturated air with water vapor with or without intermediate cooling at room temperature. By heating the samples through the air saturated with water vapor, condensed steam water is formed, which is maintained for at least the entire duration of the action of the saturated hot air.
