| This method may not accurately determine the presence of corrosive materials if the sample contains corrosion inhibitors or other chemicals which diminish the corrosivity of the sample to the copper strip. Therefore, the addition of such compounds for the sole purpose of biasing the test method is prohibited. | ||||
| At the request of the engine manufacturer, a higher MON could be used to perform the type approval tests. | ||||
