Abstract: The testing apparatus facilitates the testing of surfaces for contaminants such as soluble salts prior to applying a protective coating. The testing apparatus includes an air-permeable water-resistant membrane, an overlay, and a test chamber. When assembled, the testing apparatus provides an easily removable testing apparatus that encloses a void into which a solvent may be injected to determine the level of contamination of the surface.

Abstract: An apparatus and method are provided for characterizing a replica tape which has been embossed, compressed or cast on a surface of a material to be measured to replicate that surface. The replica tape is secured between first and second holding components such that a compressible surface of the replica tape is secured against the first holding component. A light source transmits light through the second holding component, the replica tape and the first holding component. An image sensor measures intensity of the light respectively transmitted through at least two measurement points of the compressible surface of the replica tape. A processing unit converts the measured light intensity transmitted through the at least two measurement points into at least two data values each respectively relating to a measurement statistic of the replica tape at a corresponding one of the at least two measurement points, respectively.
