If the gasoline-copper sheet corrosion test fails, will the candidate still not pass? Thank you. As I understand it, copper sheet corrosion is used to detect hydrogen sulfide, while the doctor uses it to detect hydrogen sulfide and thiols; therefore I think if the copper sheet corrosion test fails, the doctor will not approve it? I don’t know, right?
A doctor who fails the corrosion test will definitely not pass, but it is possible for a doctor to pass despite failing the corrosion test
It turns out that in our area, there was a problem where doctors failed the copper corrosion test
The Drabert test is used for the qualitative analysis of thiolic sulfur, but the presence of hydrogen sulfide in the oil will definitely result in a negative Drabert test result； Sulfides in oils can all have an impact on the corrosion of copper sheets. If the copper sheet corrosion test fails, the doctorate will not be granted
It depends on the buyer; some buyers can accept a Copper Corrosion 1A grade that fails the test, while others cannot. In most cases, a grade that is acceptable for copper corrosion fails this test
