Multifunctional interconnects, which allow to connect different (modular) robotic components mechanically as well as to ensure electrical and data transfer, do not yet exist as standardized components in European spaceflight. However, multifunctional interconnects already exist and were evaluated in a benchmark as part of the PERIOD project. The goal of the benchmark was to compare the data and power transmission as well as docking capabilities of these interconnects and also to design future testing standards. The benchmark is divided into mechanical and electrical test sections. This paper focuses on the test methodology for the electrical tests as well as describes an ontology for collecting, distributing , and reusing the results.
