    Abstract: A test station assembly for monitoring a cathodic protection system of a buried or submerged structure includes a housing including an inner chamber a connector, and an opening. In addition, the test station assembly includes a pole to connect to the connector such that an electrical conductor extending through the pole and connected to a coupon assembly is configured enter into the inner chamber. Further, the test station assembly includes a face plate to attach to the housing to at least partially cover the opening and an electrically conductive test post to connect to the face plate. Still further, the test station assembly includes a cap to cover the test post outside of the inner chamber. The cap includes an internal passage to receive the test post therein, and an opening into the internal passage to receive a probe of a voltmeter therethrough to contact the test post.

    Abstract: Methods and assemblies may be used for determining and using standardized spectral responses for calibration of spectroscopic analyzers. The methods and assemblies may be used to calibrate or recalibrate a spectroscopic analyzer when the spectroscopic analyzer changes from a first state to a second state, the second state being defined as a period of time after a change to the spectroscopic analyzer causing a need to calibrate or recalibrate the spectroscopic analyzer. The calibration or recalibration may result in the spectroscopic analyzer outputting a standardized spectrum, such that the spectroscopic analyzer outputs a corrected material spectrum for an analyzed material, and defining the standardized spectrum. The corrected material spectrum may include signals indicative of material properties of an analyzed material, the material properties of the material being substantially consistent with material properties of the material output by the spectroscopic analyzer in the first state.
