“…As discussed in the previous section detailing the Round Robin scheme, such fluctuations may be attributed to variations in the experimental set-up with respect to both the assembling of the tree simulator (in particular the string tensions), and the use of different instrumentation. Additionally, the measured vibration level is also influenced by the operator experience: inexperienced subjects have been found to operate the beater pole using stronger grip forces (Costa et al, 2013), which implies lower measured accelerations. The same trend has been observed for chainsaws by Malinowska-Borowska et al (2013), who found that higher coupling forces were exerted by inexperienced tree fellers.…”

In this paper we present the outcome of a Round Robin test carried out to validate a proposed standard procedure to measure the acceleration produced by an hand held olive harvester. Ten independent laboratories using a custom-built device were involved. The device was developed to simulate olive tree branches as far as their interaction with the harvester sticks is concerned. Collected data were analysed according to the ISO 5725-2 procedure. Accelerations measured in three of the ten laboratories were found by a cluster analysis to be statistically different from those of the remaining seven laboratories. Based on this evidence, results from the three stray laboratories were eliminated from the final sample. Laboratory data were shown to be statistically consistent with field data in the dominant front and rear X axes as well as in the rear Z axis. No statistically significant discrepancy were found for the front and the rear acceleration vector sums, which are the quantities used to quantify the occupational exposure. The procedure developed in this Round Robin test could represent a viable basis for a future test standard for hand-held olive harvesters.

“…Nevertheless exposed workers have a wrong perception of the exposure effects to HAV, as underlined by Costa et al (2013) and Vergara et al (2008), which may pose health problems because of the lack of preventive actions. Beside the scientific circles, the performance of the hand held olive harvesters is of great interest because, according to the 2006/42/EC Directive (2006), the manufacturers must declare the acceleration values in the machine instruction manual.…”
