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 ISOÂ 2631-1, ISOÂ 2631-2 and ISOÂ 2631-4) and/or hand-arm vibration (according to ISOÂ 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/TRÂ 19664.

The purpose of this technical report 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 Technical Report 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 report 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 data bases is covered.
Also this report provides proper terminology to qualify the different families of vibration sources e. g. tools, machines and working conditions (see annex B). This technical report provides a method for classifying the quality of vibration data.

This Technical Report gives guidelines for estimating, assessing and documenting the daily vibration exposure due to the use of hand-held power tools and hand-guided machines, according to the requirements of the European Physical Agents Directive (vibration) 2002/44/EC. This Technical Report is addressed to competent services for the assessment of vibration exposure at the workplace and to national authorities and industrial organisations. It helps to establish documentation for specific machinery or work situations and can also be useful for employers.
It follows the method of EN ISO 5349-1 and EN ISO 5349-2 but instead of measuring the vibration magnitudes at the specific workplaces, the methods in this Technical Report use existing vibration values from other sources of information including those provided by the manufacturers of the machinery according to the requirements of the Machinery Directive 2006/42/EC. It is important that the vibration values used in the exposure assessment are representative of those in the specific use of the machinery. Workplace measurements, however, are required if suitable data are not available to represent the vibration under the specific working conditions or if the calculation results do not help to decide whether or not the vibration exposure limit value or exposure action value is likely to be exceeded.
This Technical Report gives guidance on how to estimate the exposure duration 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 duration. Both methods can be used even in cases of multiple exposures on the same day.
Annex A gives guidance for manufacturers and suppliers of machinery concerning information that warns of risks from vibration, which should be reported to the customer.

This Standard 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.

This document describes the range of idealized values of the apparent mass modulus and phase applicable to seated individuals with and without a back support subjected to x-, y- and z‑axis sinusoidal or broad-band random vibration and to standing individuals subjected to z‑axis sinusoidal or broad-band random vibration under specific experimental conditions. Additionally, this document describes the range of idealized values of seat-to-head transmissibility modulus and phase applicable to seated individuals without a back support subjected to z‑axis sinusoidal or broad-band random vibration. The ranges of idealized values defined in this document are considered to be valid for subjects on a rigid seat (or standing on a rigid platform for z-axis only), with feet supported and vibrated. The range of idealized seat-to-head transmissibility values is considered to be applicable also to the condition with the feet hanging freely. For seated individuals subjected to sinusoidal or broad-band random vibration, the apparent mass values are defined over the frequency range of 0,5 Hz to 10 Hz for the x‑axis and y‑axis, and over the frequency range of 0,5 Hz to 20 Hz for the z‑axis. The frequency and amplitude characteristics of the vibration fall within the range for which most vibration exposure is likely to predominate while driving vehicles such as agricultural tractors, earth-moving machinery and fork-lift trucks. Application to automobiles is not covered by this document in view of the lack of a meaningful database for conditions involving posture and vibration excitation levels most likely associated with car driving. The upper and lower values of modulus and phase defined at each frequency for each of the biodynamic response functions considered represent the range of most probable or idealized values. The middle values represent overall weighted means of the human data and define the target values for general applications. Such applications can involve the development of mechanical analogues for laboratory seat testing, or of functions to correct for the human interface when representing the body as a rigid mass, or the development of analytical human body models to be used for whole-body vibration exposure estimations or for seat and cushion design optimization.

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.

This document addresses human exposure to multiple mechanical shocks, and it formulates requirements for the measurement of multiple shocks. The results of these measurements are then analyzed to provide information for the assessment of the risk of adverse health effects to the vertebral end-plates of the lumbar spine for seated individuals due to compression. Other injuries could develop even when there is no injury to the end plate. NOTE 1 Multiple mechanical shocks are shocks of different magnitude and shape that occur frequently at regular and irregular intervals during the measurement period. NOTE 2 As proposed in the annexes, the assessment of the current injury risk is based on measured representative exposures in combination with the individual exposure history. Prospective risks can be assessed by anticipated exposure durations. Manufacturers of measurement equipment are encouraged to develop a possibility for an on-site evaluation of the exposure. Two exposure regimes are distinguished in this document: one for severe conditions and one for less severe conditions. NOTE 3 Clause 4 contains the delineation of the two regimes. This document is applicable for unweighted vertical accelerations that have peak values up to 137,3 m/s2 (14 g) measured at the seat-occupant interface beneath the ischial tuberosities over a 0,01 Hz to 80 Hz measurement bandwidth. NOTE 4 The measurement bandwith is defined in 5.1. Caution is necessary when applying the method to severe exposures, particularly since peak accelerations of 137,3 m/s2 (14 g) are close to the physical limit that a spine can tolerate.

ISO/TR 18570:2017 provides guidance on a supplementary method to that defined in ISO 5349‑1 for measuring and reporting hand-transmitted vibration exposures. The method defined in this document provides an improved assessment methodology for evaluating vascular hand-arm vibration risks (vibration white finger). This document does not apply for other health effects (e.g. sensorineural and musculoskeletal disorders) induced from hand-transmitted vibration exposure (see ISO 5349‑1:2001, Annex Β). ISO/TR 18570:2017 is intended to facilitate future research on hand-arm vibration risks. It can be used to supplement the data given by the ISO 5349‑1 methodology. ISO/TR 18570:2017 cannot be used as an alternative to ISO 5349‑1. Data derived from this document cannot be used in place of ISO 5349‑1 data for fulfilling duties under national regulations, guidance or recommendations for either workplace vibration exposures or machinery vibration emissions. The methodology defined in this document is based on biomechanical and epidemiological studies which are reviewed in Annex A. Also provided in Annex A is tentative information on a relationship between vibration exposure and risk of developing vascular hand-arm vibration disorders.

ISO 14835-1:2016 specifies a) the methods for measuring the finger skin temperature (FST), b) the procedures for conducting the measurements (including the performance of cold provocation tests), and c) how to report the measurement results. The methods specified in this part of ISO 14835 are designed to assist in the collection of basic data for a quantitative evaluation of vascular response to cold provocation, and to enable specification of normative figures. ISO 14835-1:2016 is applicable to the measurement of FST in response to cold provocation for the assessment of various peripheral vascular disorders in persons exposed to hand-arm vibration, and is intended to be used together with a battery of tests for diagnosing hand-arm vibration syndrome.

This International Standard specifies, in accordance with ISO 10326-1, a laboratory method for measuring and
evaluating the effectiveness of the suspension of operator seats on agricultural wheeled tractors. It also
specifies acceptance criteria based on the test results, while defining the input spectral classes relating to
three classes of agricultural tractor with rubber tyres, unsprung rear axles and no low-frequency cab
isolation — those of up to 3 600 kg (class 1), those of from 3 600 kg to 6 500 kg (class 2), and those of over
6 500 kg (class 3) — each of which defines a group of machines having similar vibration characteristics.
The method tests the effectiveness of the seat suspension in reducing the vertical whole-body vibration
transmitted to the operator at frequencies of from 1 Hz to 20 Hz. It is not applicable to vibration reaching the
operator other than through the seat (e.g. that sensed by the operator’s feet on the platform or control pedals
or hands on the steering wheel).
NOTE The tests and criteria defined in this International Standard are intended for operator seats used in agricultural
tractors of conventional design. Tractors with design features such as isolated front or rear axles or both and
low-frequency cab suspensions, which result in significantly different vibration characteristics, can be tested in accordance
with ISO 5008 to determine a whole body vibration emission value or using other standards developed for measuring and
evaluating the effectiveness of the seat suspension on such vehicles.

1.1 This International Standard specifies methods for measuring and reporting the whole body vibration to which
the operator of an agricultural wheeled tractor or other field machine is exposed when operating on a standard test
track.
1.2 The operating conditions of the machine and the ordinates of the artificial test tracks are also included.
1.3. This International Standard applies when measurements are made on the artificial test tracks defined herein.
1.4. Measurements made under field conditions are covered in annex A.
1.5. This International Standard does not include assessment of vibration reaching the operator other than
through his/her seat or foot platform (e.g., vibration that is sensed by the feet through the controls or by the hands
through the steering wheel is not considered).
