  Recently several European National Measurement Institutes have established
traceable calibration methods for dynamic mechanical quantities, e.g., dynamic
force, torque and pressure. However, the use in industry and elsewhere of
dynamic calibration information provided on certificates is not
straightforward. Typically it is necessary to employ deconvolution techniques
to obtain estimates of measurands, and the deconvolution method itself and the
associated algorithms are sources of uncertainty that must be included in
uncertainty budgets. There is a need for practical guidance for end users on
how to use the newly-available dynamic calibration information. To this end we
set out an approach to the evaluation of uncertainties associated with dynamic
measurements that we believe covers the most relevant cases. The methods have
been embodied in publicly-available software and we show how they can be used
to tackle some example problems. We believe that the methods lead to more
reliable estimates of the relevant measurands and their associated
uncertainties.
