  We summarize the 14th meeting of the International Astronomical Consortium
for High Energy Calibration (IACHEC) held at \textit{Shonan Village} (Kanagawa,
Japan) in May 2019. Sixty scientists directly involved in the calibration of
operational and future high-energy missions gathered during 3.5 days to discuss
the status of the cross-calibration between the current international
complement of X-ray observatories, and the possibilities to improve it. This
summary consists of reports from the various WGs with topics ranging from the
identification and characterization of standard calibration sources,
multi-observatory cross-calibration campaigns, appropriate and new statistical
techniques, calibration of instruments and characterization of background,
communication and preservation of knowledge, and results for the benefit of the
astronomical community.
