Description

Technical Field

[0001] The invention belongs to the technical field of product detection, and in particular relates to a device and method for testing the corrosion resistance of cookware. Background Art

[0002] The specific method of corrosion resistance test is usually adjusted according to different standards and product types. For cookware, a common test method is to immerse the cookware in a sodium chloride solution with a concentration of (50±5)×10-6 and keep it at 22±4℃ for 16 hours; during this process, it is necessary to conduct normal visual inspection on the surface of the product to observe whether there is any corrosion; if corrosion is found, it can be judged that the material of this batch of products is unqualified; in addition to sodium chloride solution, other reagents are also used in corrosion resistance testing. For example, after 168 hours (7*24) of testing, it may be necessary to use the detergents and rinse agents specified in ENV 12875-1 to clean the cookware in a household dishwasher at 65℃; however, the specific situation will be determined according to different test standards and methods.

[0003] Problems with existing technologies:
