ISO/TS 15694:2004 specifies methods for measuring single shocks at the handle(s) of hand-held and hand-guided machinery characterized by a maximum strike rate below 5 Hz.

ISO/TS 15694:2004 also defines additional requirements for the measuring instrumentation which is necessary for the evaluation of shocks.

The aim is to facilitate the gathering of emission and human exposure data in order to provide a basis for emission declaration and for the future development of exposure risk criteria. However, ISO/TS 15694:2004 does not provide methods for the interpretation of the potential human effects of single shocks.

It is therefore a basis for measurement and evaluation of emission of single shocks from hand-held and hand-guided machinery but does not cover the evaluation of human exposure.
