EN 13059:2002+A1:2008 (E) 6 Introduction This European Standard has been prepared to be a harmonized standard to provide one means of conforming to the essential safety requirements of the Machinery Directive and associated EFTA regulations. This European Standard is a type C standard as stated in EN 1070.
The aim of this standard is to provide a method for the measurement of vibration emission transmitted to the whole body of operators of industrial trucks which will enable the information requirements of the Machinery Directive to be satisfied. It is intended that the results obtained also can be used to compare industrial trucks of the same category or a given truck when equipped with different seats or tyres, etc. This standard cannot be used for field measurements to determine the daily exposure of the operator to vibration. For the measurements trucks shall be fitted with equipment corresponding to that offered by the manufacturers on the standard truck data sheet (lifting devices, batteries, etc.). Type test measurements require accurate and reproducible results. It is essential that different establishments obtain comparable results within specified limits. This requires that the process or way in which the machinery is used during the measurement is precisely defined. This process will reproduce the whole-body vibration values typical of the machinery when in normal travelling use. In the case of industrial trucks, there may be three predominant operating modes: travelling, lifting and engine idling; of these, only travelling exposes the driver to significant whole-body vibration. Therefore, in accordance with EN 1032, the test for whole-body vibration is based on the travelling operating mode. Research has shown that the magnitude of hand-arm vibration on the steering wheel or control levers of trucks will normally be lower than 2,5 m/s2. Therefore no test method has been developed for its measurement. In practice, exposure over a working day is a mixture of the three modes and the average vibration values will generally be lower than the values given by this standard. Fitting the industrial trucks with different seats, changing the tyres, etc. can lead to different vibration values. Due to the specific operation of industrial trucks however, the existing EN 1032 standard cannot be applied directly, so that preparation of this standard for industrial trucks became necessary. Although studies showed that it is possible to obtain repeatable and representative results with all-terrain trucks tested on an artificial test track, this family of trucks is covered by Informative annex A. The reason is that an inexplicable difference of about 20 % was found in the emission from one truck when it was tested at two different times of the year. Further consideration should be given to including all-terrain trucks in the normative section of the standard when more data is available for these trucks. For the verification of the measurements the uncertainty is fixed at 0,3 times the vibration emission value reported in accordance with EN 12096. Further consideration should be given to revise this range of uncertainty when emission vibration data obtained from different places is available.

EN 13059:2002+A1:2008 (E) 7 1 Scope This European Standard is a type test procedure for establishing the values of vibration emission transmitted to the whole body of operators of industrial trucks under specified conditions. It is not applicable to hand-arm vibration. This standard is applicable to powered industrial trucks listed in ISO 5053:1987. The annex A is applicable for "all-terrain" trucks. It also applies to other powered industrial trucks not covered by ISO 5053:1987, e.g. variable-reach trucks and "low-lift" "order picking" trucks, etc.
NOTE The standard may however be useful also for existing trucks. This standard is not applicable to non-stacking "low-lift" straddle carriers (as specified in 3.1.3.2.3 of ISO 5053:1987) and stacking "high-lift" straddle carriers (as specified in 3.1.3.1.11 of ISO 5053:1987). The test results, however, are not applicable to the determination of whole-body vibration exposure. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter.

EN 13059:2002+A1:2008 (E) 8 3.2 wheel diameter arithmetic mean of the outside diameters of the load bearing wheels, e.g. : if the truck has some wheel(s) of diameter D1, some wheel(s) of diameter D2 and some wheel(s) of diameter D3, the wheel mean diameter equals (D1 + D2 + D3)/(number of tyre sizes fitted) The outside diameter, D, is the maximum in service diameter quoted in the ETRTO manual (see annex D) for the size(s) and type(s) of tyres fitted. If a tyre is not listed, consult the tyre's manufacturer. 3.3 tyre the tyre can be pneumatic or solid. Amongst the solid tyres a distinction can be made between high-load "non-rubber" solid tyres (Vulkollan, Contilan, etc.) and rubber solid tyres Rubber solid tyres can be fitted to a cylindrical or conical base (e.g. cushion "bandages") or to a pneumatic tyre rim (e.g. super elastic tyres). 3.4 seat base surface on which the seat and its suspension, if fitted, are mounted 3.5 seat pan seat surface on which the operator is seated 4 Quantities to be measured The quantities to be measured are as follows: 4.1 aw,z: root mean square (r.m.s.) acceleration of whole-body vertical frequency-weighted vibration in accordance with EN 1032; 4.2 aw,zF: mean value of N r.m.s. weighted vertical acceleration values of a valid test series measured on the floor of the driving position with one standing operator; 4.3 aw,zS: average of acceleration mean values obtained for each of the two operators for a valid test series measured on the seat pan under the seated operator; 4.4 the mean truck speed when travelling on the test track. This may be determined from the time taken to drive along the test track or by means of the measuring instruments specified in 5.2; 4.5 pneumatic tyre pressures shall be checked; 4.6 ambient air temperature.

In the case where the measurements are made on a seat pan the transducer shall be mounted in a semi rigid disc as described in EN 1032:1996, 5.2. In the case where the measurements are made at the seat base or on the floor the transducer shall be firmly fixed to rigid parts of trucks e.g. by means of a magnet, or adhesive, etc. NOTE In the case of stand on trucks, it is convenient to mount the transducer on a light rigid plate upon which the operator can place both feet. 5.1.3 Frequency weighting Frequency weighting and band limiting characteristics shall be in accordance with 5.3 of EN 1032:1996. 5.1.4 Integration time For each run, the r.m.s. acceleration shall be a linearly integrated average over one complete test run (see 8.2). 5.2 Truck speed The truck speed on the test track shall be measured using instruments measuring the average speed with an accuracy of ± 5 %. NOTE An alternative method is to measure the time to travel over the full length of the test track. From knowledge of the length of the track and the time taken to travel it, the truck average speed is calculated. 6 Vibration measurement direction and location 6.1 Measurement direction Measurement shall be made in the vertical (Z) direction. 6.2 Measurement location In the case where the exposed persons are sitting, the transducer mounted in a semi rigid disc 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 (Figure 1). SIST EN 13059:2003+A1:2008
EN 13059:2002+A1:2008 (E) 10 When measurement at the seat base are made (see 7.2), the transducer shall be firmly mounted, preferably at the centre of the seat base mounting; where this is not possible, it shall be mounted outside the seat base mounting at the same level as the seat base on a stiff part towards the side of the truck (see Figure 1) perpendicular to the direction of travel and as close as possible to the seat centre.
In the case where the exposed persons are standing on a driving or a working platform, the transducer shall be located (see 5.1.2) at a point immediately adjacent to the feet of the standing operator (preferably between the feet). NOTE When the position of the standing driver can influence the results, the intended position of the driver should be clearly identified. 7 Set up and equipment 7.1 General The trucks shall be categorized on the basis of tyre types and the wheel mean diameter. The test track is constructed basically of two obstacles. Further details shall be taken from Table 1 and Figures 2 and 3. 7.2 Test track The test track is a straight track and consists of a level, smooth length (l) surface with two rigid obstacles each 15 cm wide of rectangular cross section (e.g. hard wood, metal, etc.) to drive over. The deflection of the obstacle material shall be negligible. Figures 2 and 3 illustrate the test track and obstacles. The length (l) of the test track and the height of the two obstacles shall be chosen from Table 1. The total length of test track will also include a sufficient distance at each end to allow the truck to build up to the required speed at the actual start of the run and to slow down and turn at the end of the run. The test track surface shall be made of hard material like tarmac, concrete, etc. The smoothness of the surface shall also be such that the r.m.s. acceleration of the frequency weighted vertical vibration (aw,z) measured at the seat base or foot plate when the truck is travelling over the test track without the obstacles is less than 50 % of the value measured at the same location when the truck is travelling over the test track with the obstacles. The conditions for the measurements made without obstacles are the same as with the obstacles. Before starting the measurements it is essential the test surface shall be cleared of any loose chippings, etc. It is essential that the obstacles do not move on the test track surface. NOTE 1 The relationship between measurements made on the seat with and without obstacles is generally smaller than the same measurements made at the seat base. NOTE 2 If the truck is equipped with a low frequency suspended cab (resonant frequency below 10 Hz), it is recommended to make the measurements on the chassis at a point aligned as closely as possible to a point vertically below the seat centre (see 6.2). NOTE 3 If the vibration measured at the seat base or foot plate with obstacles is less than 0,5 m/s2, then the 50 % criterion can be ignored. 7.3 Equipment and condition of the truck 7.3.1 Truck Measurements shall be carried out on a new, properly serviced truck. Where a single truck is to be measured and then taken as representative of a truck family, it shall be fitted with equipment corresponding to that offered by the manufacturer on the standard truck data sheet (lifting devices, SIST EN 13059:2003+A1:2008
EN 13059:2002+A1:2008 (E) 11 batteries, etc.). For individual measurements and special equipment, the specific equipment shall be listed. 7.3.2 Load Trucks of categories 1, 2, 3 and 4 (see Table 1) shall be tested with a load of 01060− % of the rated load capacity of the truck at the rated load centre distance. Trucks of category 5 shall be tested unladen for practical reasons. Pallet trucks shall be tested with the load support arms raised. 7.3.3 Tyres The truck shall be fitted with new tyres. Pneumatic tyres shall be properly inflated in accordance with the truck manufacturer's instructions. The final inflation pressure verification shall be carried out immediately before and after the vibration testing. If a deviation of more than 10 % is noted on the tyre inflation pressure before and after the test the vibration tests shall be repeated.
If a truck can be equipped with different types of tyres (e.g. pneumatic tyres, resilient solid tyres, cushion tyres (bandages) or high-load "non-rubber" solid tyres), at least one series of measurements shall be made for each type of tyre. NOTE When the relevant dynamic characteristics of the tyres and truck are known, then the truck can be tested with just one tyre type and the vibration calculated for other types of tyre. 7.3.4 Trucks with a cab If or when a truck can be fitted with a cab with or without a suspension, measurements shall be carried out for both cases. If the driver's cabin position can be moved horizontally, then measurements shall be carried out at the extremes of that movement and the highest values of vibration emission shall be reported (see clause 9). If the driver's position can be moved vertically, then measurements shall be carried out in the lowest position. 7.3.5 Trucks with seated operators The seat (or seats) shall be adjusted such that the driver can comfortably reach the necessary controls. If the truck is equipped with a suspension seat, the suspension shall be adjusted to the driver's weight and to avoid topping and bottoming of the mobile part of the seat suspension. If a truck can be fitted with different models of seat, measurements shall be carried out for each model of seat. 7.4 Operators 7.4.1 Standing operator Measurements shall be made with one operator with a mass of 01075− kg. 7.4.2 Seated operator Measurements shall be made with one operator with a mass of 01075− kg if the seat which is fitted to the truck being tested has passed the seat laboratory test code (see EN 13490) for the corresponding category of truck.
