Introduction of a test solution that artificially simulates the components of sweat used in immersion corrosion tests for sweat.
Human sweat varies greatly between individuals and can change based on diet and physical condition, making it difficult to establish a standard for sweat. Additionally, collecting sweat from individuals for each test requires considerable effort. Our company offers "artificial sweat solution," which is artificially prepared to mimic human sweat. The "artificial sweat solution" is a testing liquid similar in composition to sweat and can be used for immersion corrosion tests. We can prepare formulations tailored to your needs, so please feel free to contact us. [Main tests using artificial sweat solution] ■ Sweat resistance test - Inspection and evaluation of product durability (color) and stain resistance ■ Sweat resistance, durability, and corrosion resistance tests - Inspection and evaluation of product durability (color) and sweat resistance and corrosion resistance *For more details, please refer to the PDF document or feel free to contact us.
