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. ... The appearance of corrosion products (rust or other oxides) is evaluated after a pre-determined period of time.

Expert ASTM B117 salt fog and cyclic corrosion testing, with Houston’s largest salt fog (and cyclic) chamber and PhD corrosion consulting. B117 is widely used as a rapid method for evaluating coating and materials performance under highly corrosive marine conditions. ASTM B117 is commonly used for metals, plastics, woods, and coated materials of all kinds; ideally to compare two or more materials.

We say ‘years’ because the exact amount depends on the conditions of exposure and there is no agreed-upon correlation factor; the goal of the test is to provide a uniform environment where different coatings and materials can be compared against each other. Whether you need to qualify a coating, test a new alloy, or evaluate materials for offshore service, we have the expertise and capabilities to help you rapidly determine the answer.

The samples, which varies in size and shape, are exposed to a 5% salt fog or spray that is even distributed among the samples inside our B117 testing chamber. The sample chambers are checked twice daily for collection rates, water pH, and temperature throughout the test.

That really depends on what you’re testing. If it’s a large components or system, then absolutely! Our biggest salt fog chamber is 8' x 10', and up to 7' tall, so we can accommodate big structures or hundreds of samples at a time.  We have tested engines, car doors, frames, motors, metal booths, and large coated parts of all types, in both salt fog and cyclic corrosion conditions.

The option to test many parts at once helps ensure they all are exposed to the same daily conditions and fluctuations (otherwise there is some variance even between identical systems during normal operation).

The test results can be examined visually to measure the integrity of the alloy and or its coating. Comparisons of pre- and post-testing photos will be taken and if needed a comparison of a corroded sample from the field may also be used. Weight loss or gain are recorded before and after exposure to estimate the corrosion rate. Monitoring of pH and water collection is performed at the twice a day. Then we provide a thorough report with data, analysis, pictures, and discussion that helps you understand and apply the results.

Salt spray corrosion test chamber is one of the "three proofs "(hot and humid, salt spray, mold) test equipment in artificial climate environment. It is an important test equipment for studying various environmental adaptability and reliability of machinery, national defense industry, light industry, electronics, instruments and other industries.It is widely used in accelerated salt spray corrosion tests of metal protective coatings, mechanical parts, electronic components and industrial products.The performance indexes meet the requirements of GB/T5170.8 "verification methods of basic parameters of environmental testing equipment for electrical and electronic products".The salt spray corrosion test chamber can conduct various salt spray tests according to GB/T2423.17 "basic environmental test procedures for electronic and electrical products test Ka: salt spray test methods" and equivalent IEC, DIN, MIL, ASTM and other standards.In addition to the neutral salt spray test, can also be used for acetate spray test.

All C&W cabinets with their clean functional design are manufactured from high quality materials selected specifically for this application. They are made out of specially formulated fire retardant glass reinforced polyester (GRP) with high chemical and temperature tolerance. The apex lids are formed in a range of composite materials depending on test requirements and supported by gas springs to ensure smooth operation and an effective seal when closed to ensure full insulation. Over-temperature protection is factory set and the control panel is ergonomically designed. Transportation in areas of restricted access is made easier due to the compact design aided by wheels and removable lids.
