    The 'standard model' of radiographic exposure technique allows for generation of exposure technique variables in various forms. A Microsoft Excel spreadsheet application and additional dedicated 'Add- In' functions are described that implement the standard model. The Visual Basic for Applications (VBA) coded application (named 'StandardXp') is a menu driven system and allows for traditional fixed kVp and variable kVp method solutions as well as the variable source to image distance (SID) method and also 'combination method' (simultaneous variation of tube voltage and tube charge) types of solution. The associated set of 'Add-In' functions also enable the same solutions (using any of the methods just mentioned), to be obtained. Aspects of implementation of the standard model in the coded calculations are described, and some limitations of the StandardXp application and functions in generating usable exposure charts are also discussed. Such limitations are suggested to be mainly due to limitations of the standard model itself
