CEN/TC 231 - Mechanical vibration and shock

The aim of this document is to provide information on the possible adverse health effects caused by exposure to vibration at work. The report addresses manufacturers, companies which introduce machinery on the EU market as well as employers and employees using vibrating machinery in order to improve their understanding of the possible health problems arising from occupational exposure to vibration.
This document is limited to the effects on health and does not cover the potential effects of vibration on comfort, human performance, or vibration perception. Most of the information on whole-body vibration in this document is based upon data available from research on human response to vibration of seated persons. There are only few data on the effects of vibration on persons in standing, reclining or recumbent positions.
The information on both hand-transmitted vibration and whole-body vibration is based upon data from laboratory research on acute effects as well as upon data from epidemiologic field-studies at workplaces.
Additional information can be obtained from the scientific literature.

This document specifies a laboratory method for measuring the vibration at the handle of fastener driving tools. It is a type test procedure for establishing the vibration value on the handle of a hand-held power tool operating under a specified load.
This document is applicable to fastener driving tools driven pneumatically or by other means, using nails, staples or pins.
This document is applicable to tools with single sequential actuation, contact actuation, contact actuation with automatic reversion or continual contact actuation (see Figures 1 to 3).
This document is not applicable to tools operating in full sequential mode due to their much longer intervals in between individual actuations. However, to provide an indication for comparison of different tools of this type (see Figures 4 and 5), Annex C provides informative guidance.
NOTE       Today current knowledge does not allow any conclusions regarding physiological and pathological effects between isolated shocks and continuous shock sequences, and their repetition rates.

This document specifies minimum requirements for personal vibration exposure meters (PVEM).
This document is applicable to instruments designed for measurements of whole-body vibration in the context of industrial hygiene applications (according to ISO 2631-1, ISO 2631-2 and ISO 2631-4) and/or hand-arm vibration (according to ISO 5349-1) together with the associated exposure times.
This document provides specified design goals and permitted tolerances that define the minimum performance capabilities and functional requirements of instruments designed to measure personal daily vibration exposure.
This document does not apply to instruments designed to measure or log exposure times without also performing vibration measurement. Instrumentation of this type is described in ISO/TR 19664.

This document gives guidelines for estimating and documenting the daily vibration exposure due to the use of hand-held power tools and hand-guided machines, in relation to the requirements of the European Physical Agents Directive (vibration) 2002/44/EC. This document is addressed to competent services for the assessment of vibration exposure at the workplace and to national authorities and industrial organizations.
The methods in this document are based on the requirements and guidance given in EN ISO 5349 1 and EN ISO 5349 2 but instead of measuring the vibration magnitudes at the specific workplaces, the methods in this document use existing vibration values from other sources of information including those provided by the manufacturers of the machinery in relation to the requirements of the Machinery Directive 2006/42/EC.
This document gives guidance on how to estimate the exposure time and the daily vibration exposure A(8) as defined in EN ISO 5349 1. It also offers a simple method for estimating the daily vibration exposure by means of a table which indicates the vibration exposure as a function of the equivalent vibration total value and the associated exposure time. Both methods can be used even in cases of multiple exposures on the same day.

The purpose of this document is to give guidelines for elaborating databases on human vibration for different purposes (emission or immission) and types of exposure (hand-arm vibration or whole-body vibration).
This document is restricted to cases where vibration affects persons at work. It is mainly addressed to competent services for the assessment of vibration exposure at the workplace and to national authorities and industrial organizations.
It defines basic requirements to get databanks respecting quality criteria (information to be given regarding exposure, reference standards, machines, persons, key parts, data origin and traceability) taken into account the type of exposure (HAV, WBV).
Although this document has been mainly designed to facilitate the exchange of data between experts, a section explains the minimum information to be provided and precautions to be taken for databases opened to public. The way the data should be formatted to facilitate the exchange between developers of databases is covered.
Also this document provides proper terminology to qualify the different families of vibration sources e.g. tools, machines and working conditions (see Annex B). This document provides a method for classifying the quality of vibration data.

This document specifies a laboratory method for measuring hand-transmitted vibration emission at the handles of hand-held power-driven angle and vertical grinders. It is a type-test procedure for establishing the magnitude of vibration in the gripping areas of a machine fitted with a specified test wheel and run under no‑load conditions. The method has been established for surface grinding tasks only. Cutting and sanding generally create lower vibrations. It is intended that the results be used to compare different models of the same type of machine.
This document is applicable to hand-held machines (see Clause 5), driven pneumatically or by other means, intended for grinding, cutting-off and rough sanding, with bonded, coated and super-abrasive products and with wire brushes for use on all kinds of materials. It is not applicable to die grinders or straight grinders.
NOTE    To avoid confusion with the terms "power tool" and "inserted tool", machine is used for the former throughout this document.

The assessment of human exposure to vibration, to both the hand-arm system and the whole body, at the workplace relies on the combined evaluation of both vibration magnitudes and exposure times. Determining these values can employ various instrumentation types and data sources. ISO/TR 19664:2017 provides guidance and explanation of concepts used for the following:
-      measurement processes;
-      instrumentation types;
-      vibration magnitude source.

ISO 8041-1:2017 specifies the performance specifications and tolerance limits for instruments designed to measure vibration values, for the purpose of assessing human response to vibration. It includes requirements for pattern evaluation, or validation, periodic verification and in situ checks, and the specification of vibration calibrators for in situ checks.
Vibration instruments specified in this document can be single instruments, combinations of instrumentation or computer-based acquisition and analysis systems.
Vibration instruments specified in this document are intended to measure vibration for one or more applications, such as the following:
-      hand-transmitted vibration (see ISO 5349‑1);
-      whole-body vibration (see ISO 2631‑1, ISO 2631‑2 and ISO 2631‑4);
-      low-frequency whole-body vibration in the frequency range from 0,1 Hz to 0,5 Hz (see ISO 2631‑1).
Vibration instruments can be designed for measurement according to one or more of the frequency weightings defined within each of these applications.
Three levels of performance testing are defined in this document:
a)    pattern evaluation or validation:
      pattern evaluation, i.e. a full test of the instrument against the specifications defined in this document;
      validation of one-off instruments, i.e. a limited set of tests of an individual vibration measuring system against the relevant specifications defined in this document;
b)    periodic verification, i.e. an intermediate set of tests designed to ensure that an instrument remains within the required performance specification;
c)    in situ checks, i.e. a minimum level of testing required to indicate that an instrument is likely to be functioning within the required performance specification.

ISO 10326-1:2016 specifies basic requirements for the laboratory testing of vibration transmission through a vehicle seat to the occupant. These methods for measurement and analysis make it possible to compare test results from different laboratories for equivalent seats.
It specifies the test method, the instrumentation requirements, the measuring assessment method and the way to report the test result.
ISO 10326-1:2016 applies to specific laboratory seat tests which evaluate vibration transmission to the occupants of any type of seat used in vehicles and mobile off-road machinery.
Application standards for specific vehicles refer to this document when defining the test input vibration that is typical for the vibration characteristics of the type or class of vehicle or machinery in which the seat is to be fitted.
NOTE          Examples of application standards are given in the bibliography.

This European Standard specifies the determination of whole-body and hand-arm vibration emissions at operator position(s) during testing of mobile machinery. The purpose of this European Standard 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 European Standard provides requirements for the preparation of vibration test codes, 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.
Vibration test codes based on this European Standard should define measuring procedures which provide accurate and reproducible results which are as far as possible in agreement with values measured under real working conditions. For determination of the magnitude of the vibration to be noted in the instruction handbook, this European Standard requires operating conditions enabling the determination of the 75-percentile of the vibration experienced at the operator's position during the mode of operation causing the highest vibration.
This European Standard applies to sitting and standing positions. It is applicable to all mobile machinery producing

This European Standard gives guidelines to ensure that manufacturers of machines provide adequate information on application of vibration isolation to reduce the risks arising from vibration generated by their machines. Guidelines are also provided to ensure that users furnish sufficient information regarding their applications to suppliers of machines or, where applicable, to the supplier of the isolation system, to enable the optimum selection and design of vibration isolation.
This European Standard is restricted to source isolation.
Although this standard is primarily intended for the use of new machines, it may be applied to the installation of used machines, too.
This European Standard is addressed to manufacturers and installers of a machine, as a guide to define relevant parameters for the choice and installation of a vibration isolation system to be used with the machine.
NOTE   This European Standard may also be applied by users of machines already installed, who use or wish to use vibration isolation to solve a vibration problem caused by the machine.
This European Standard shall not be considered as a manual for the design or installation of an isolation system. Examples of elements of vibration isolation are shown in annex A only for information.

1.1   This European Standard is applicable to operator seats used on industrial trucks as defined in
ISO 5053:1987 irrespective of power supply, type of equipment, lifting mechanism and tyres. It also applies to seats for other trucks not covered by ISO 5053:1987, e.g. variable-reach trucks and lowlift order picking trucks.
1.2   This European Standard specifies, in accordance with EN 30326-1, a laboratory method for measuring and evaluating the effectiveness of the seat suspension in reducing the vertical wholebody vibration transmitted to the operator of industrial trucks at frequencies between 1 Hz and 20 Hz.
1.3   This European Standard defines the input spectral classes required for the following industrial trucks. Each class defines a group of machines having similar vibration characteristics:
-   Platform trucks, trucks rider-controlled, etc. with wheel mean diameter below 200 mm and highload non-rubber solid tyres (category 1)1)
-   Reach trucks, articulated trucks, etc. with wheel mean diameter below 450 mm and high-load non-rubber solid tyres or cylindrical/conical base rubber solid tyres (category 2)1)
-   Straddle trucks, trucks with wheel mean diameter below 645 mm and rubber solid or pneumatic tyres (category 3)1)
-   Straddle trucks, trucks with wheel mean diameter between 645 mm and 900 mm and rubber solid or pneumatic tyres (category 4a)1)

NOTE   Other tests may be appropriate for machines with d

ISO 20643:2005 provides the basis for the drafting of vibration test codes for hand-held and hand-guided power-driven machinery. It specifies the determination of hand-transmitted vibration emission in terms of frequency-weighted root-mean-square (r.m.s.) acceleration during type testing. For machines where vibration test codes do not exist, it can also be used for determination of emission values and contains sufficient guidance for designing an appropriate test. It is applicable to hand-held power tools (e.g. chipping hammers, sanders), hand-guided powered machines (e.g. lawn mowers, single-axle tractors, vibratory rollers), and other types of powered machines fitted with handles, guiding beams or similar means of control, of all power sources (electrical, hydraulic, pneumatic, internal combustion engine, etc.). It is not applicable to fixed machinery in which the vibration is transmitted to the hands of the user through the workpiece, nor to vibration transmitted from steering wheels or control levers of mobile machinery where the operator's position is on the machine.

This International Standard specifies a procedure to determine the vibration transmissibility of a resilient material when loaded by the hand-arm system. The method is applicable to all materials which behave in a linear way. It is expected that this is realized in most elastic foam and rubber materials and, provisionally, in woven cloths. The method can be applied to mixed systems, e.g. a cloth material attached to a foam or rubber base. It is expected that the results of this laboratory test will be used in screening materials used for vibration attenuation on the handles of tools and for gloves. This will enable rank ordering of materials for gloves, but will not necessarily predict the transmissibility of the gloves fabricated from these materials (for this purpose, see ISO 10819).

This European Standard provides guidelines for the measurement and evaluation of whole-body vibration at the workplace.
This European Standard describes the precautions to be taken to make representative vibration measurements and to determine the daily exposure time for each operation in order to calculate the daily exposure value standardized to an 8-h reference period. This European Standard provides a means to determine the relevant operations that should be taken into account when determining the vibration exposure.
This European Standard applies to situations where people are exposed to whole-body vibration at the workplace, transmitted through the buttocks for a seated person or through the feet for a standing person.
This European Standard is restricted to the evaluation of exposure to whole-body vibration using quantities derived from frequency-weighted root-mean-square acceleration. The frequency range considered is 0,5 Hz to 80 Hz. Where the vibration includes shocks or impacts, methods in this European Standard may underestimate the severity of the exposure. There is a need to assess the risks arising from exposure to whole-body shocks and high crest factor vibration. Methods for this are beyond the scope of this European Standard.

This Technical Report provides best practices and methods available for limiting the effects of mechanical whole-body vibration on operators' positions. The guidelines given outline practical ways in which whole-body vibration hazards associated with mobile machinery can be reduced by machinery design. The Technical Report covers four important aspects of the reduction of the effects arising from exposure to hazardous machinery vibration:
a)   identification of main sources and operational modes producing vibration that might be hazardous to health and of additional factors worsening the adverse health effects of vibration on the operators;
b)   reduction of vibration magnitudes at source;
c)   reduction of transmission of vibration from source to the operator;
d)   ergonomic adaptation of operators' position: posture, range of vision.
This Technical Report does not provide universal or detailed technical solutions but only a review of engineering methods available. It is not concerned with hand-arm vibration which is covered by CR 1030-1.
This Technical Report is primarily intended as a guideline for people involved in purchasing, using, supplying, marketing or inspecting mobile machinery. It is also intended to be a guidance for writers of type C standards for specific types of machinery.

This Technical Report outlines practicable measures for the reduction and control of exposure to whole-body vibration at workplaces in order to provide a practical professional aid to workplace managers and health and safety officers. It covers identification and reduction of health risks from exposure to hazardous machinery vibration at the particular workplace, corresponding to Articles 4, 5 and 6 in the EU Directive 2002/44/EC, including
-   identification of main sources of whole-body vibration at the workplace,
-   formulation of a strategy for minimising and control of vibration exposure and
-   implementation of the strategy.
NOTE   Although the term vibration covers continuous vibration and transient vibration (shocks), in this Technical Report shocks are referred to in special cases where they require special attention.
This Technical Report is not concerned with hand-arm vibration which is covered by CR 1030-2.

ISO/TS 15694:2004 specifies methods for measuring single shocks at the handle(s) of hand-held and hand-guided machinery characterized by a maximum strike rate below 5 Hz.
ISO/TS 15694:2004 also defines additional requirements for the measuring instrumentation which is necessary for the evaluation of shocks.
The aim is to facilitate the gathering of emission and human exposure data in order to provide a basis for emission declaration and for the future development of exposure risk criteria. However, ISO/TS 15694:2004 does not provide methods for the interpretation of the potential human effects of single shocks.
It is therefore a basis for measurement and evaluation of emission of single shocks from hand-held and hand-guided machinery but does not cover the evaluation of human exposure.

This part of ISO 5349 provides guidelines for the measurement and evaluation of hand-transmitted vibration at the workplace in accordance with ISO 5349-1.
This part of ISO 5349 describes the precautions to be taken to make representative vibration measurements and to determine the daily exposure time for each operation in order to calculate the 8-h energy-equivalent vibration total value (daily vibration exposure). This part of ISO 5349 provides a means to determine the relevant operations which should be taken into account when determining the vibration exposure.
This part of ISO 5349 applies to all situations where people are exposed to vibration transmitted to the hand-arm system by hand-held or hand-guided machinery, vibrating workpieces, or controls of mobile or fixed machinery.

This European standard establishes the requirements for declaration and verification of vibration emission values. It applies to hand-arm and whole- body vibration values achieved by measurements according to type-B and Type-C standards. It gives guidance on the declaration of vibration emission values; it describes vibration and product information to be given in technical documents supplied to users by the manufacturer.
