Overview

This standard specifies special requirements for measuring hand-transmitted vibration emission at the handles of hand-held power driven portable die grinders. It is also applicable to low-speed die grinders using flap wheels or cylindrical sleeves; it does not apply to straight grinders, however. This standard describes a laboratory measurement method for determination of the type-test values (vibration emission values) which shall be given in the instructions. This standard supports essential requirements of the Machinery Directive. This standard differs from DIN EN ISO 8662-13 as follows: a) vibrations are to be measured in three axes and, where applicable, at both hand positions; b) new transducer locations have been specified; c) specifications relating to the measurement directions have been revised; d) vibrations due to grinding are to be measured under real working conditions. The International Standard ISO 28927-12 has been prepared by ISO/TC 118/SC 3 "Pneumatic tools and machines" in collaboration with CEN/TC 231 "Mechanical vibration and shock". The responsible German committee is Committee NA 001-03-07-02 (NALS/VDI C 7.2) "Hand-Arm-Schwingungen" ("Hand-arm vibration").
