Patent ID: 8232812

Claim:
A process for determining a corrosive material in an interior of a motor vehicle, the process comprising: providing a piece of electrically conducting material; providing a piece of potentially corrosive material used within an interior of a motor vehicle; providing an electrical resistance measuring device; providing a testing chamber; placing the piece of electrically conducting material and the piece of potentially corrosive material in the testing chamber; electrically connecting the piece of electrically conducting material to the electrical resistance measuring device; monitoring an electrical resistance of the piece of electrically conducting material as a function of time; wherein an increase in the electrical resistance across the piece of electrically conducting material is a result of a corrosion agent being released from the piece of potentially corrosive material, coming into contact and chemically reacting with the piece of electrically conducting material, and corroding and reducing a cross section of the piece of electrically conducting material; and no increase in the electrical resistance of the piece of electrically conducting material is a result of a corrosive element not being released from the piece of potentially corrosive material and the piece of electrically conducting material not having a reduction in the cross section due to corrosion.
