Spherical coordinate three-dimensional (3D) imaging systems, such as Terrestrial Laser Scanners (TLS), are already used widely in different fields. Their measurement performance evaluation is a topic of active research. In 2017, the first comprehensive documentary standard describing performance evaluation methods and procedures for TLS systems, the ASTM E3125-17, was released. In this paper, we report on the first realization of the test procedures per that standard. We briefly discuss the test procedures and then describe the materials and methods used to realize the tests. We then discuss the test measurands (the quantities of interest in the testing procedure), present the test values (the measured values of the test measurands), and the test value uncertainties (uncertainties in the testing process, which is typically the uncertainty in the reference length). The work described in this paper will serve as a useful reference for understanding and implementing the ASTM E3125-17 standard.
