FD CEN ISO/TS 15694
Mechanical vibration and shock - Measurement and evaluation of single shocks transmitted from hand-held and hand-guided machines to the hand-arm system
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.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
With Requirements, quickly access the main part of the normative text!
