Mechanical vibration - Testing of mobile machinery in order to determine the vibration emission value
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

Key 1 Supporting surface NOTE For description of the directions, see 6.1.1. Figure 1 — Directions of the basicentric coordinate system for mechanical whole-body vibration influencing human beings 6.1.2 Translational hand-transmitted vibration from a steering wheel is related to the steering wheel as follows: x-direction: the radial direction, y-direction: the direction tangential to the rim of the steering wheel, z-direction: the direction orthogonal to both the x-direction and the y-direction. These directions are illustrated in Figure 2. SIST EN 1032:2004+A1:2009
NOTE For description of the directions, see 6.1.2. Figure 2 — Directions of measurement on steering wheels 6.2 Location of measurement 6.2.1 For whole-body vibration measurements, vibration should be determined as close as possible to the point or area through which the vibration is transmitted to the body. a) In the case where the exposed persons are sitting, the transducer mounted in a semi-rigid disc (see 7.2) shall be placed on the surface of the seat such that the transducer is located midway between the ischial tuberosities of the seated person. For comfort reasons, it is acceptable if the centre of the disc is located slightly in front (up to 5 cm) of the ischial tuberosities. b) In the case where the exposed persons are standing on a driving or a working platform, the transducer shall be located with the operator standing as in Figure 1 with the transducer midway between the arches of the feet. NOTE Backrest vibration is not dealt with in this European Standard. 6.2.2 For hand-transmitted vibration measurements, vibration should be determined as close as possible to the point or area through which the vibration is transmitted to the hand. Measurements on the steering wheel shall be carried out adjacent to the normal position of a hand guiding the steering wheel. If the test code also requires measurements to be made on controls (e.g. levers), they shall be carried out as close as possible to the hand which touches the control in a normal way. 6.3 Magnitude of vibration The quantity used to describe the magnitude of vibration shall be frequency-weighted acceleration in m/s2, expressed as a root-mean-square (r.m.s.) value aw. Frequency weightings to be used are defined in 7.3. The acceleration aw in accordance with this European Standard is defined as the r.m.s. value of the frequency-weighted acceleration signal aw(t): SIST EN 1032:2004+A1:2009
(1) Requirements for the integration time T are given in 7.4. NOTE 1 Frequency analysis is recommended in order to check the validity of the measurements and to provide information for the improvement of designs. NOTE 2 The measurement of hand-transmitted vibration should be inspected for the effects of operator-induced movements and either these effects removed from the signal or a period selected for analysis which is free of these artefacts. 6.4 Multi-axial vibration measurements The measurements shall normally be made in three directions. The following values shall be determined. For whole-body vibration:
awx, awy, awz
(2a) aw max = max{1,4 awx, 1,4 awy, awz}
(2b) For hand-transmitted vibration:
ahwx, ahwy, ahwz
(3a) []212hwz2hwy2hwxhv/aaaa++=
(3b) where awx, awy and awz (for hand-transmitted vibration ahwx, ahwy and ahwz) are the r.m.s. values of the frequency-weighted acceleration in the x-direction, y-direction and z-direction, respectively. NOTE Where it is shown that there is a dominant direction, the vibration test code can specify that the vibration be measured in one direction only, which needs to be stated. For hand-transmitted vibration, in this case the value ahv is the r.m.s. value of the weighted acceleration in that direction. A direction can be regarded as dominant when the r.m.s. value of the frequency-weighted acceleration in each of the other directions, in the case of whole-body vibration multiplied by 1,4 for x- and y-directions, is less than 66 % of that in the dominant direction. 7 Instrumentation requirements 7.1 General Unless otherwise specified by the relevant vibration test code the dynamic range, sensitivity, accuracy, linearity and overload capacity of the vibration measuring system shall be in accordance with !EN ISO 8041". Measuring equipment may comprise transducers (usually accelerometers), conditioning amplifiers and filters, telemetry set (optional), recorders and/or meters. !The tolerances of the vibration measuring instrumentation are specified in EN ISO 8041." SIST EN 1032:2004+A1:2009
Key 1 Thin metal disc for accelerometer mount and added centre rigidity 2 Appropriate cavity for accelerometer(s) Figure 3 — Design of a semi-rigid mounting disc The disc shall be as thin as possible and be of approximately 80 Shore-A to 90 Shore-A moulded rubber or plastic material. NOTE 1 For practical reasons, it is usually not possible to perfectly align the accelerometers in the disc with the directions of the basicentric coordinate system. In a tolerance range within ± 15° of the appropriate directions the accelerometers can be considered as aligned parallel to these directions. The transducers used for the measurement at the feet of a standing operator shall be rigidly fixed on the working platform. If the working platform is covered by a resilient material, the transducers may be mounted in the middle of a rigid metal plate (about 300 mm × 400 mm) with the operator standing on the plate. The transducers used for hand-transmitted vibration measurements on the steering wheel shall be mounted firmly to the steering wheel, for example by using a threaded stud or clamp. The total mass of the accelerometers and mounting devices (stud or clamp) should not be more than 50 g (and preferably not more than 30 g). The mounting device should be selected to minimize the distance between the accelerometers and the vibrating surface of the steering wheel and the distance should not exceed 15 mm. NOTE 2 There are several problems in making repeatable measurements on a steering wheel. In particular, the measurement can be strongly affected by steering movements made by the operator. Care is needed to minimize these, e.g. by making the measurements during travelling on a straight course. NOTE 3 Tangling of signal carrying wires on the steering column can be eliminated by attaching the wires to a spoke on the steering wheel and trailing them to the centre of the wheel. Alternative mounting conditions or specific formed mounting discs or adaptors may be specified in the specific vibration test code. SIST EN 1032:2004+A1:2009
!EN ISO 8041". 7.6 Calibration of the measurement chain The whole measurement chain shall be checked both before and after a sequence of measurements. NOTE It is also important to check regularly that the whole measurement chain is also calibrated at other frequencies throughout the frequency range of interest. In addition to regular calibration (e.g. every two years), calibration is also necessary after rough handling of any important part of the measurement chain. The results of the calibration check shall be recorded. The transducers shall be calibrated in accordance with ISO 5347 and ISO 16063. The whole measurement chain shall be checked following the requirements in !EN ISO 8041". 7.7 Errors of measurement Annex C provides information on possible sources of errors of measurement.
