The transport of dangerous goods (TDG) is a field where the precision of control, measurement and event data of electronic equipment is crucial. To ensure the necessary level of precision, high-level standards are fundamental. Therefore, new EN 15969-1:2022 ‘Tanks for transport of dangerous goods - Digital interface for the data transfer between tank vehicle and with stationary facilities - Part 1: Protocol specification - Control, measurement and event data’, which addresses this need, is a welcome addition to CEN’s portfolio.
