Title:
CORROSION TESTING METHOD
Document Type and Number:
WIPO Patent Application WO/2010/016265
Kind Code:
A1
Abstract:
Disclosed is a corrosion testing method suitable for the evaluation of corrosion resistance of a member constituting an electric and electronic equipment such as an electric wire with a terminal that is utilized under such an environment that corrosion proceeds relatively mildly. In the corrosion testing method, for example, granules of a nonmetallic insulating material and an electrolyte-containing fluid are brought into contact with a sample (1) that comprises a terminal member (11) mounted on the end of an electric wire (10) comprising an insulating layer (10i) provided on the outer circumference of a conductor (10c). In this state, the sample (1) is held for a predetermined period of time to corrode the sample (1). More specifically, an electrolyte-supported material comprising the granules with an electrolyte deposited on the surface thereof is provided. The electrolyte-supported material is spread on the sample (1), and the sample (1), with which the electrolyte-supported material is in contact, is held in a constant temperature and humidity state within a thermo-hygrostat for a predetermined period of time. An electrolyte-containing fluid produced from the electrolyte in the electrolyte-supported material and moisture contained in an atmosphere in the thermo-hygrostat is brought into contact with the sample (1), whereby the terminal member (11) is corroded by utilizing the fluid.
