Salt Spray Test: Salt Spray Test (盐雾试验)
An accelerated corrosion test in which samples are exposed to a fine salt mist in a closed chamber. It evaluates the corrosion resistance of plated teeth, sliders and end parts, with white rust and red rust appearance times used for rating. Salt concentration, temperature, pH and test duration are controlled by the chosen standard. Results guide plating thickness and process changes, and acceptance limits are agreed between buyer and supplier.
