Metal Test Laboratory

ISO 4536 Metallic and Non-Organic Coatings on Metallic Surfaces - Salt Droplet Corrosion Test (SD Test)

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 4536 testing. This international standard specifies the test solution, apparatus and procedure for brine droplet corrosion testing on metallic substrates, in accordance with the requirements of the coating or product specifications, for the assessment of the quality of metallic and inorganic coatings.

ISO 4536 Metallic and Non-Organic Coatings on Metallic Surfaces - Salt Droplet Corrosion Test (SD Test)

The specified test method is suitable for detecting defects and discontinuities in cathodic metal coatings to the underlying metal. It is also suitable for chemical or electrochemical conversion coatings such as those obtained by chromate and phosphate processes. The method is not suitable for testing coatings for heavier duty types.

The type and number of test samples, the exposure times to be used for a particular product, and the interpretation of results are not specified in this international standard. Such details should be given in the appropriate material or coating specifications.

The method has the advantages that it only needs simple, easily controlled apparatuses and can be applied to objects of complex shape.

The corrosion method with a pattern of discrete droplets has been used with various solutions for tests to evaluate the resistance of a coating to certain environments.
