  4. AP219 NWI Scope: • Information requirements for analyzing the data and reporting the results of dimensional inspections of solid parts or assemblies. Certain information used for administering, planning, and executing dimensional inspection as well as archiving the results is also required in the analysis activity. Dimensional inspection can occur at any stage of the life cycle of a product where checking for conformance with a design specification is required. • Excluded: Dimensional inspection of liquid surfaces, the materials properties of parts, manufacturing activities, and mathematical algorithms to perform the dimensional inspection analysis.
