Calculating hand–arm vibration doses and limits

The chart published by the Health and Safety Executive (1994) can also be used

to calculate A(8) values. Figure 11.1 shows how this is done.

The previous standards for carrying out hand-arm vibration assessments, ISO

5349:1989 and BS 6842:1987 allowed the use of the highest of the three axis values

rather than a root-sum-of-squares (rss) combination of the three.
