Daily usage time evaluation and it’s influence on exposure-response models for vibration-induced white finger
* Presenting author
Abstract:
Exposure-response models take various parameters into account. The model included in ISO 5349-1:2001 for vibration-induced white finger, as well as those in previous publications by the authors, include directly the lifetime exposure time and the 8-h energy-equivalent, frequency-weighted averaged acceleration value, A(8). The latter combines the daily usage time and the frequency-weighted triaxial acceleration. Several publications found that the value of the daily usage time varies depending on the method, such as questionnaire interview or measurement, used to determine it and the respective tool. Two studies quantified the difference between methods for several tools. These factors can be applied to unify data from studies in which different methods were used. This contribution analyzes how eliminating such method related differences in daily usage times by means of these factors affects exposure-response models previously created by the authors.
