Following detailed analysis of the operating conditions and thanks to experience shared by the customer, a suitable grease was developed for testing. This involved drawing up various development approaches and evaluating them in a range of laboratory tests.
In order to test the grease under real-life conditions, a test plan was drawn up in coordination with the customer. This plan included all the information and framework conditions needed for the approval test, such as the duration of testing, the applications to be lubricated in the test, and the time intervals between sampling.
Following a thorough risk evaluation, it was decided that a grease sample would be taken at an appropriate point every six weeks. The total duration of this approval test was set at a minimum of one year, such that it was possible to cover all four seasons. At the same time, the short intervals between grease sampling and evaluation meant that component failure was practically ruled out.
Rhenus Lub was responsible for approval testing, including sampling, laboratory analysis and the accompanying documentation. Once the trial period was complete, the documented results were collated and presented to the customer. The new lubricant was then approved in light of the absence of any complaints and given the total satisfaction with the product. Since then, the customer has been making full and successful use of the new lubricant.
