Standards Development

Scope

This document specifies the determination of whole-body and hand-arm vibration emissions at operator position(s) during testing of mobile machinery. The purpose of this document is to assist technical standardization committees responsible for specific types of machinery in preparing vibration test codes to ensure that such vibration test codes

— are as homogeneous as possible with each individual test code having the same basic structure,

— are in full accordance with basic standards on measurement of vibration emission,

— reflect the latest technical knowledge of methods of determining the vibration emission from the specific family of machinery under consideration,

— provide manufacturers with a standardized method for the determination and declaration of the vibration emission value(s) of their machinery,

— enable the user of the machinery or the member of an inspection body to compare the vibration emission values of different machinery and to verify the vibration emission values provided by the manufacturer.

This document provides requirements for the preparation of vibration test codes (C-type standards), including guidelines for the conditions under which the measurements shall be made (e.g. operating conditions). Information to be included in a typical vibration test code is summarized in Annex A.

This document applies to sitting and standing positions. It is applicable to all mobile machinery producing periodic or random vibration with or without transients. This document contains sufficient guidance for designing an appropriate test for machinery for which no vibration test codes exist. It can also be used for the determination of vibration emission values of individual machines. This document is not applicable to rotational vibration and backrest vibration. This document does not present limits or recommended vibration values.

Purpose

New requirements from Machinery Regulation (EU) 2023/1230 need to be implemented in EN 1032.
