Earth-moving machinery. Laboratory evaluation of operator seat vibration Ingestion-build-82061 9 General requirements1 Scope 1. 1 This document specifies, in accordance with ISO 103261: 2016, a laboratory method for measuring and evaluating the effectiveness of the seat suspension in reducing the vertical whole body vibration transmitted to the operator of earth moving machines at frequencies between 1 Hz and 20 Hz. It also specifies acceptance criteria for application to seats on different machines.
