Guide for Improving the Statistical Quality of Dry Coating Thickness Data on Ferrous and Non-ferrous Metal Substrates Using Continuous Read/Scanning Technology

The guide presents a summary of past research that provides evidence of improved statistical quality of coating thickness data, reviews existing standards referencing continuous read/scanning technology, describes instrumentation requirements, explores various probe traversing patterns based on the geometry of the structure/item being inspected, presents the advantages and limitations of employing continuous read/scanning methodology, proposes best practices for data management, and provides suggested language to assist the specifier in invoking requirements for obtaining a greater population of coating thickness measurements on a project.

This guide is intended to inform specifiers about the use of continuous-read or scanning technologies for quickly obtaining large numbers of coating thickness readings. These technologies may be specified for use on projects that would benefit from analysis of large batches of coating thickness readings.
