- Scope
- This standard specifies the general method for the measurement and reporting of human hand-transmitted vibration, that is, the measurement of 1/3 octave band with a center frequency of 6.3 to 1250 Hz and the octave band with a center frequency of 8 to 1000 Hz in three orthogonal axes. , Frequency weighting measurement covering frequency 5.6 ~ 1400Hz. This standard only gives the method of evaluating hand-transmitted vibration according to frequency-weighted acceleration and daily vibration exposure time, and does not specify the safe vibration exposure limit. This standard applies to periodic, random or aperiodic vibration. For the time being, it is also suitable for repetitive shock vibration.
