Methods for Using a Salt Spray Chamber to Test a Material’s Rust Resistance
A specialised piece of laboratory equipment called a salt spray chamber , sometimes referred to as a salt fog or salt spray test chamber, is used to perform accelerated corrosion testing on materials, coatings, and final products. A salt spray chamber's main function is to replicate and evaluate the corrosive effects that environmental factors, especially those that are high in salt, can have over time on various materials. Using a salt spray test chamber , materials are tested for rust resistance by putting them in a controlled corrosive atmosphere that mimics real-world circumstances. The process usually adheres to ISO 9227 or ASTM B117, which are standardised testing methods. An overview of how to do a salt spray test is provided here: Creation of Salt Solution: Use distilled water to dissolve high-purity sodium chloride (NaCl) to create a salt solution. Typically, the concentration is 5% of the total weight. Chamber Setup: Make sure there are no impurities...
