COPPER STRIP CORROSION (P: 15, D 130, IP 154, ISO 2160)

Most sulfur compounds in petroleum are removed during refining. However, some residual sulfur compounds can have a corroding action on various metals. This effect is dependent on the types of sulfur compounds present. The copper strip test is used to determine the corrosiveness to copper brass or bronze of diesel fuel. Corrosive action is of particular significance in the case of pressure burner vaporizing tubes that operate at high temperatures. This test also determines the corrosiveness to copper of various gasolines, fuels, lubricating oils or other hydrocarbons.
