Typical salt spray test results of zinc
Electrical bonding measurement test resultsafter removal from bath, cleaning, and threeday wait (post168hr salt spray test and clean). The plug connectors were demated from the receptacles for inspection. Images were taken of the receptacle and plug side of the mounting bracket. These are shown inthe salt spray test. The salt spray test can give similarly misleading results when comparing different variants of zinc coatings. For example, small additions of magnesium or aluminium to a zinc coating will produce salt spray test results that differ significantly from real exposure conditions. Magnesium ions, whether from the environment (sea typical salt spray test results of zinc
Salt spray testing is performed by placing samples in a test chamber designed in accordance with ASTM B117 and operated in accordance with the specified conditions in ASTM B117. The test solution to be sprayed is prepared by dissolving pure sodium chloride into pure water, in a ratio of 5 sodium chloride to 95 water, by weight.
Prohesion Compared to Salt Spray and Outdoors Cyclic Methods Of Accelerated Corrosion Testing and rapid cycling between spray and dry conditions. Test results are shown comparing Prohesion to natural nies using this equipment that a typical test consists of a one hour spray cycle at ambient temperature followed by a one hour Different coatings have different behavior in salt spray test and consequently, test duration will differ from one type of coating to another. For example, a typical electroplated zinc and yellow passivated steel part lasts 96 hours in salt spray test without white rust. Electroplated zincnickel steel parts can last more than 720 hours in NSStypical salt spray test results of zinc test chamber at 95F with continuous exposure to an atomized fog of salt solution. Salt spray test results provide a method of comparison testing of coatings in a controlled environment, but may not directly predict corrosion protection in real world conditions. Consult the standards for specific minimum salt spray testing requirements
