What is Salt Spray Test Used For?

Salt spray testing is usually used to supply brief comparisons between expected and real corrosion resistance. In reality, there may be most effective a vulnerable correlation between the coating’s length within the test and its real expected existence. This is because of the fact that many outside factors affect corrosion—it’s not an easy procedure. This is especially true for substances like warm dip galvanized steel, wherein drying cycles are a vital factor to take into account for durability.

For this reason, salt spray trying out is only while used on samples to determine a bypass-or-fail grade and compare it to salt spray test chamber expectations, typically in a first-rate audit function or to check for the effectiveness of a specific production technique.

Salt spray assessments are used on phosphate surfaces, zinc and zinc-alloy plating, electroplated tin, copper, nickel, and chromium, natural coatings, paint coatings, and coatings that aren’t applied electrolytically.
