Salt spray test - Wikipedia

The salt spray or salt fog test is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.

This test can be used to test the relative resistance to corrosion of coated or uncoated aluminium alloys and other metals, when exposed to a changing climate of acidified synthetic seawater spray, followed by a high humidity, both at an elevated temperature.

Montado vertical u [ Different coatings have different behavior in salt spray test and consequently, test duration will differ from one type of coating to another. Salt spray testing is popular because it is relatively inexpensive, quick, well standardized, and reasonably repeatable.

So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level. This website has been developed with modern browsers in mind to normw it to display normma its best in a wide variety of viewing situations - including mobile viewing.

So the tests are quite similar with the exception of the EES variant.

Salt Spray Fog Testing Equipment for ASTM B and DIN 50

Electroplated zinc-nickel steel parts can last more than hours in NSS test without red rust or 48 hours in CASS test without red rust Requirements are established in test duration hours and coatings shall comply with minimum testing periods. Salt spray testing is an accelerated corrosion test that produces a corrosive attack to coated samples in order to evaluate mostly comparatively the suitability of the coating for use as 5002 protective finish. Variations to the salt spray test normaa depend upon the materials to be tested.

Although the majority of salt spray tests are continuous, i. The can filling head fastens onto the vacuum filler discharge to ensure neat and effective filling and [ The concentration of salt in solution is approximately equivalent.

The test duration is variable. This spray is set to fall-out on to the specimens at a rate of 1.

Please note The test standard summaries are for general guidance only. The longer the accelerated 50201 test, the longer the process remains out of control, and larger is the loss in the form of non-conforming batches.

The salt spray test has borma application in predicting how materials or surface coatings will resist corrosion in the real world, because it does not create, replicate or accelerate real-world corrosive conditions.

In the automotive industry requirements are specified under material specifications. In this context they can be considered to be equivalent and interchangeable terms. The equipment manufacturers should provide you with a statement indicating to which specifications their equipment complies. The principal application of the salt spray test is, therefore, enabling quick comparisons to be made between actual and expected corrosion resistance.

This produces a corrosive environment don dense salt water fog also referred to as a mist or spray in the chamber, so that test samples exposed to this environment are subjected to severely corrosive conditions. This is followed by 3.

Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises the following 2 part repeating cycle.
