ROSE, at least in the U.S., is an acronym for Resistivity of Solvent Extract test. In Europe, it is more commonly called Solvent Extract Conductivity (SEC) testing, as Graham indicates. The two are merely inverses of each other. One defines ionic cleanliness based on the resistivity of the solution and the other on the conductivity (the inverse of resistivity) of the solution.
