Test procedure for measuring the geometric features of a test specimen

摘要

The test procedure for measuring a geometric feature of a test specimen employs a replicating compound to obtain a casting with a negative image of the geometric feature followed by forming a protective covering over the casting from a replicating compound having a contrasting color. The casting and protective covering unit is cut to obtain a test piece and a flat bed scanner is used to scan the profile of the test piece and obtain an electronic two-dimensional image of the profile for analysis.
