Ding Testing & Inspection: Salt Spray Test Experts, Safeguarding the Corrosion Resistance of Metal Materials
Salt spray testing is an accelerated method that artificially simulates the corrosion process of materials in marine or high-salt fog environments, used to evaluate the corrosion resistance of metal materials and their coatings. Ding Testing & Inspection's salt spray testing service professionally simulates salt fog environments to assess the corrosion resistance of materials, ensuring product quality and reliability.
Service Introduction
Salt spray testing is an accelerated corrosion assessment method using an artificial atmosphere. It involves atomizing a specific concentration of saline solution and spraying it into a sealed, constant-temperature chamber. The corrosion resistance of the tested samples is reflected by observing the changes after a period of exposure. This accelerated testing method uses salt concentrations in the fog that are several to dozens of times higher than those in natural environments, significantly increasing the corrosion rate and dramatically reducing the time required to obtain results.
Testing Methods
-
Neutral Salt Spray Test (NSS)
-
Acetic Acid Salt Spray Test (AASS)
-
Copper Accelerated Acetic Acid Salt Spray Test (CASS)
-
Alternating Salt Spray Test
Among these, the Neutral Salt Spray Test is the most common, with test durations typically being 24 hours, 48 hours, 72 hours, 96 hours, and longer durations up to 1000 hours or even 2000 hours.
Industry Pain Points
The industry's pain points lie in the corrosion issues that materials and products may face during actual use, which can affect the lifespan and safety of products, especially in marine or high-humidity environments.
