coefficient of variation, C v , and the standard deviation, s n-1 , shall be calculated for each hand position for each of the three operators The C v of a test series is defined as the ratio of s n-1

the vibration emission values of a batch of machines, are stated to lie when the machines are new DD.10.2 Tests on single machines For tests made on only a single machine, K shall be given as K = 1,65
