The document specifies a method to give an indication of the ability of an adhesive tape to cause corrosion. If amounts of water-soluble ions are negligible (pH near neutrality and low conductivity of aqueous extract) this indicates that the adhesive tape is suitable for applications where corrosion must be avoided. Adhesive tapes with higher concentrations of water-soluble ions may cause corrosion in use. This test may be useful for electrical applications where the adhesive tape is in contact with metallic surfaces.
