Astm d130 corrosiveness to copper from petroleum products by copper strip test a polished copper strip is immersed in a specific volume of the sample being tested and heated under conditions of. Commercial and hd 5 grade propane is required to pass the copper strip corrosion test astm test method d 1838.

Application to propane with carbonyl sulfide and hydrogen sulfide. In standardized test method astm d130 for oils or d4048 for grease the rating of 1a is given for appearance of freshly polished copper coupons and 1b indicates slight tarnish. These ranges include freshly polished slightly tarnished 1a to 1b moderately tarnished 2a to 2e dark tarnish 3a to 3b and corrosion 4a to 4c. This must be done at the right depth as per the astm requirements.

While it is known that hydrogen sulfide will cause the failure of the copper strip test it is widely believed that the hydrolysis of carbonyl sulfide can also cause the failure of the corrosion test. 1b 2b dark tarnish 3b 4a corrosion 4b 4c code oapi viscosity. Testing up to four copper strips at a time. Visual rating incorporating.
