This document provides the basis for the drafting of vibration test codes for hand-held and hand-guided powerdriven machinery. It specifies the determination of hand-transmitted vibration emission in terms of frequencyweighted root-mean-square (r.m.s.) acceleration during type testing. For machines where vibration test codes do not exist, it may also be used for determination of emission values and contains sufficient guidance for designing an appropriate test.NOTE Vibration test codes based on this document should define measuring procedures which provide controlled, repeatable and reproducible results which are, as far as possible, in agreement with the v
