The corrosion level which is reached after the end of the test is evaluated by comparing the copper strip with a colour scale.
The result is described in four main categories (1-4) and within this in two to five sub-categories (a-e).

| OELCHECK Test equipment: | Copper strips and heating bath |
| Sample quantity needed: | 50 ml |
| Unit: | No |
| Test result: | Corrosion level 1 - 4 |
| Operating time: | About 1.5 hours for Oil and 24 hours for grease |
| Analysis of: | Mineral oil and grease |
| Brief description: | A grinded, polished and degreased copper strip is going to be dunked into a sample vessel which contains the test liquid. If grease has to be investigated the copper strip is brushed on both sides with grease. This prepared copper strip goes into a sample vessel, which contains the same grease. The closed sample vessel is dunked into a heating bath for a defined period of time. After the end of the test duration the copper strip is removed from the sample vessel. The copper strip is cleaned with solvent and becomes carefully dried. The corrosion level which is reached after the end of the test is evaluated by comparing the copper strip with a colour scale. The result is described in four main categories (1-4) and within this in two to five sub-categories (a-e). |
| Statement: | The method is used to verify the corrosion characteristics from lubricants and greases at copper. Corrosion at metals results amongst others from sulphur compounds which are part of the oil. It depends furthermore from the sulphur-species, which is used in the oil. Only absolute amount of sulphur allows no statement to the expected corrosion from metallic components. |
