TEST MEDIUM FOR THE RAPID ANALYSIS OF ENGINE OILS IN INTERNAL COMBUSTION ENGINES

摘要

The present invention relates to a test medium for the rapid analysis ofengine oils ininternal combustion engines,having a weight per unit area of 50.0 to 200.0 g/m2,comprising, based on the total weight of the test medium,20.0% by weight to 98.0% by weight of cotton pulp,0.0% by weight to 50.0% by weight of cellulose and0.1% by weight to 50.0% by weight of silicic acid and/or at least one silicatesalt.The present invention also relates to a method for the rapid analysis ofengine oils ininternal combustion engines, in which a drop of an engine oil to be analysedis applied tothe test medium according to the invention and is allowed to penetrate intothe testmedium, and the test result is then preferably compared with at least onereference imagein order to determine the condition of the engine.
