TEST APPARATUS AND METHOD FOR TESTING A SURFACE

Method for testing a surface using a test apparatus comprising a holding plane onto which holding plane the surface to be tested may be arranged, and where at least two different nozzles are arranged in a gantry distanced from the holding plane and directed such that the nozzles can direct a flow of testing media towards and impacting the holding plane, where the method comprises the following steps:
- determining the location where the surface to be tested is to be placed or used;
- retrieving samples of debris present at the location;
- creating at least two test fluids, which test fluids may be one or more suspensions containing at least part of some of the samples of debris, and/or means for introducing at least part of some of the samples of said debris into an airstream or liquid stream;
- arranging a sample of the surface to be tested in the holding plane;
- connecting a first nozzle to a first test fluid via a pump and conduits and a second nozzle via a pump and conduits to a second test fluid, and directing the first and second nozzles such that the nozzles will issue test fluid impacting against the surface;
- activating the gantry and the pump(s), such that the first and second nozzles will traverse the surface while issuing test fluid.
