The effort to characterise detector sensors and components for the High Luminosity upgrade of the CERN Large Hadron Collider requires collaboration between irradiation facilities around the world. By convention, the radiation damage following irradiation with particle beams is reported as the 1 MeV neutron equivalent fluence, obtained using the corresponding hardness factor. Measurements of proton hardness factors at three different kinetic energies are presented, by characterisation of commercially available diodes before and after irradiation, using irradiations at the University of Birmingham, the Karlsruhe Institute of Technology, and CERN. Possible future improvements to these measurements are also discussed
