EPTA Procedure 05: Single Impact Energy
European Power Tool Association (EPTA) Procedure 05 provides a common method for the determination of the single impact energy for rotary hammers and breakers.
It defines a standardized measurement method, which ensures comparability between different tools and member companies.
The parameters defined in this procedure are standardized, whereas the real parameters can vary, e.g. due to different working conditions, bit dimensions, condition of work piece.
