Samples with missing information, or samples whose origin cannot be clearly identified, may take a bit longer as the data processing department may need to query certain details. Also, samples that appear to have severe problems may be sent back to the laboratory so that extra tests can be carried out. These are usually the samples that do not make the 24 hour turnaround.
Although WearCheck runs an oil testing laboratory, the actual analysis is carried out in a process that resembles a production line. This takes place in order to ensure a quick turnaround time for the large number of tests that are performed on each sample. However, it does mean that samples received later in the day may not enter the process stream until the next morning.
In the event of an emergency, every effort will be made to process a sample as timeously as possible within the working constraints of the many departments involved.
- Normal - no action required, wear levels, contamination levels and lubricant health are all within acceptable limits.
- Borderline - problems are indicated when there appears to be a deviation in trend or when a defined parameter has just been exceeded. In effect, the report is saying, the readings are not following their normal pattern but there is no firm evidence that a problem exists. The recommended action will be quick and simple to carry out and its primary function will be to determine if any further action needs to take place. No drastic steps need to be taken. Borderline samples can be attended to at the next regular service. In these situations, doing nothing more than taking a check sample may be a perfectly acceptable reaction to a borderline report.
- Urgent - samples indicate that there is a very strong likelihood that a problem exists. Again, the report will only recommend some confirmatory check to be carried. With urgent samples these checks will usually be greater in number and may require more time and effort to carry them out in order to supply more information about the condition of the component. Urgent samples should be attended to as soon as it is convenient to do so.
- Critical - samples definitely indicate that a problem exists and that it is quite severe in nature. These problems, ideally, should be attended to immediately. It is important to note, that even at this point, it would be extremely unusual for a strip-down to be recommended. The first action that should take place following the receipt of a critical report is to read what the diagnosis says.
