We perform gasoline quality testing by ASTM D7667 to determine the corrosiveness to silver by automotive spark-ignition engine fuel. Crude petroleum contains sulfur compounds, most of which are removed during refining. However, of the sulfur compounds remaining, some can have corroding effect on various metals. This corrosivity is not necessarily directly related to the total sulfur content. Under some circumstances, reactive sulfur compounds in fuel can tarnish or corrode silver alloy fuel gauge in-tank sender units or silver-plated bearings (in 2-stroke cycle engines). The silver strip corrosion test is designed to assess the relative degree of corrosivity of a petroleum product towards silver and silver alloys.
Sample quantity required: 100 ml
