EN 13406:2002 (E)4IntroductionThe objective of this standard is to specify test methods and requirements that, as far as possible, allow uniformtesting and evaluation of slurry tankers.The methods and requirements aim at evaluating the slurry tankers and the spreading devices regarding the user'sability, when he uses the machine according to the manufacturer instruction handbook, to:¾ control the application rate;¾ attain an even distribution of the slurry;¾ reduce the load on the external environment, for example by not unintentionally spreading slurry outside thetarget area.It should be noted that there is often a great number of varieties of a machine type and also varieties of spreadingdevice. This should be considered when selecting the machine configuration for the tests, with the aim of reducingthe necessary number of machines to be tested.This standard is developed for the evaluation of a complete machine (through transverse and longitudinal tests).The standard can also be used for testing a single piece of the equipment in the form of a spreading device only(transverse tests and pressure/flow measurements) or a tanker only (longitudinal tests and pressure/flowmeasurements).SIST EN 13406:2004



EN 13406:2002 (E)51 ScopeThis European Standard specifies test methods and requirements for the design and construction of slurry tankersfor broadcasting and band spreading of slurry in agriculture and horticulture with the intention of minimising theenvironmental damage.It specifies requirements for the transverse and longitudinal spreading characteristics such as working widths,characteristic application rate, characteristic flow and the stretch within the tolerance zone.NOTEThe application of this standard alone will not be sufficient to deal with all the environmental aspects. Other aspectssuch as ammonia emission, odour reduction etc. should be considered.These requirements are valid only according to the tests with slurry as described in Table A.1.Personal safety aspects have not been considered in this standard. These aspects are covered by EN 707.2 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply.2.1slurry tankermachine for handling, transporting and distributing slurryKey1Pump or compressor2Tank3Connection point4Spreading devicea) Mechanically powered slurry tankerb) Pneumatically powered slurry tankerFigure 1 — Basic components of a slurry tanker2.2broadcasting spreading devicedevice intended to distribute the slurry over the field surface2.3band spreading devicedevice intended to distribute the slurry in bands separated by bands with no slurry over the field surface or in thesoil2.4working widthdistance between the centre of two adjacent boutsSIST EN 13406:2004

The calculated CV for this additional test shall then be lower than 20 %.SIST EN 13406:2004



EN 13406:2002 (E)73.2.2 Band spreading devices – Average deviationNOTEThe method for the collection of slurry in the transverse tests (e.g. the size of the collecting containers), is differentfor band spreading devices than for broadcasting spreading devices. Therefore, it would be inappropriate to use the CV fordescribing the evenness of spreading for band spreading devices too, since that can lead to misleading comparisons of theevenness of spreading e.g. between different band spreading devices.The tested unit shall, for a specific setting, have an average deviation which is lower than 15 %.The average deviation shall be calculated according to 4.3.1.2.The test shall be completed in accordance with 4.2.1 and the requirement shall be fulfilled for the setting of flowsdefined in 4.2.1.3.If the requirement is not met for one of the settings, one additional test shall be completed with that same settingand with slurry selected as specified in 4.1.2 to check the lack of temporary default; this shall be noted in the testreport. The calculated averaged deviation for this additional test shall then be lower than 15 %.3.3 Longitudinal distribution3.3.1 Characteristic application rateA test shall be made to check that it is possible to obtain the lowest characteristic application rate specified by themanufacturer, when the forward speed used is lower than 8 km/h. This characteristic application rate shall bestated in the test report.The test shall be made in accordance with 4.2.2 and the calculation of the characteristic application rate shall bemade in accordance with 4.3.2.3.3.2 Stretch within the tolerance zoneThe stretch within the tolerance zone determined at a specific setting shall exceed 90 % of the unloading time.The test shall be made in accordance with 4.2.2 and the calculation of the stretch within the tolerance zone shall becompleted according to 4.3.3.The requirement shall be fulfilled for settings defined in 4.2.1.3.If the requirement is not met for one of the settings, one additional test shall be completed with that same settingand with slurry selected as specified in 4.1.2 to check the lack of temporary default; this shall be noted in the testreport. The calculated stretch within the tolerance zone for this additional test shall then be longer than 90 % of theunloading time.4 Verification4.1 Test conditions4.1.1 Slurry tanker and spreading deviceThe unit to be tested shall be used in accordance with the instructions given in the instruction handbook. If a slurrytanker is equipped with an agitation device, this device shall operate to avoid separation of the slurry. If theinstructions limit the use of the unit, in relation to 4.1.2, this shall be noted in the test report.When only the spreading device is tested, it can either be mounted on a tanker or mounted in any other way thatallows slurry to be supplied from a separate pump (similar to an umbilical system). In all cases the mounting shallallow measurements of pressures and corresponding flows.When only the tanker (without spreading device) is tested, the tanker shall be connected to equipment that allowspressure/flow measurements to be performed at different backpressures of the spreading devices (for examplethrough a variable valve).SIST EN 13406:2004



EN 13406:2002 (E)8If a complete machine is tested, no pressure measurement at the connection point is necessary.All pressure measurements shall be made at the connection point for the attachment of the spreader to the tanker(see principle in Figure 1). The inclination of the feeding pipe at the connection point shall be in accordance withthe information given by the manufacturer and shall be recorded in the test report.The inner diameter of the pipe at the connecting point and its height above ground shall be stated in the test reporttogether with a schematic drawing of the connecting point.The level of liquid in the tanker at the beginning and at the end of the test shall be stated in relation to theconnecting points.4.1.2 SlurryThe slurry is classified in one class as described in annex A. The physical properties of the slurry used in the testsshall be determined in accordance with annex A and shall be stated in the test report.4.1.3 Filling of slurryThe slurry shall be uniformly agitated before filling the slurry tanker. The test shall be started within 15 min after thefilling procedure has been completed.4.1.4 Test site and ambient conditionsThe tests shall be carried out on an even, horizontal surface, indoors or outdoors.In the case of broadcasting spreading devices the following also applies:¾ the unit to be tested shall be oriented with the driving direction as far as possible against the direction of thewind;¾ during the transverse distribution tests the wind velocity shall not exceed 3 m/s, measured 1,5 m above groundlevel with a limit deviation of ± 0,5 m/s;¾ the average values for the wind velocity and wind direction shall be stated in the test report.4.1.5 Containers for collecting slurry in the transverse distribution test4.1.5.1 Broadcasting spreading devicesThe containers shall have external dimensions of 500 mm ´ 500 mm, with a limit deviation of ± 2 mm, with amaximum wall thickness of 3 mm and with a minimum depth of 100 mm.Measures shall be taken to avoid spillage of slurry by ricochets out of the containers e.g. by inserts in thecontainers. The upper edges of the containers shall all be at the same level within ± 10 mm, and maximum 100 mmabove the average ground level.NOTEIt is preferable to keep the upper edges of the containers as close as possible to either the ground or, if the tanker iselevated during the tests so that wheels are above containers, to the lowest part of the wheels of the tested unit.4.1.5.2 Band spreading devicesThe containers shall be designed so that one container can be placed under each outlet.4.1.6 Accuracy in weighing of collected slurryThe collected slurry shall be weighed with a limit deviation of ± 10 g or ± 0,5 % of the reading, whichever is thehighest value.SIST EN 13406:2004



EN 13406:2002 (E)9NOTESince climatic variations can influence the mass of the slurry, there should be as short a time interval as possiblebetween the weightings.4.1.7 Device for measuring the flow of slurry4.1.7.1 GeneralThe flow of slurry shall be determined either by registration of the changes of the mass of the tested unit and thetime elapsed since the beginning of the test, or by the use of equipment for direct flow measurements.4.1.7.2 By registration of mass and timeThe mass shall be registered with a limit deviation of ± 10 kg or ± 0,5 % of the reading, whichever is the highestvalue. The signal transmitted to the registration equipment shall have a resolution of at least 1 kg.The time shall be registered with a limit deviation of ± 0,01 s or ± 0,1 % of the reading, whichever is the highestvalue. The signal transmitted to the registration equipment shall have a resolution of at least 0,01 s.4.1.7.3 By registration of the flowThe flow shall be registered with a limit deviation of ± 1 l/s or ± 1 % of the reading, whichever is the highest value.The signal transmitted to the registration equipment shall have a resolution of at least 1 l/s.NOTEThis accuracy can be reached by using an electromagnetic flow meter.4.1.8 Device and method for measuring pressureThe pressure shall be measured with a limit deviation of ± 25 kPa (0,25 bar) or ± 5 % of the reading, whichever isthe highest value.The pressure shall be measured at a distance, at least five times the pipe diameter, from any bend or change inpipe area. The aperture for the measuring device shall be oriented perpendicular to the direction of the pipe.NOTEThe measurement can also be made with an electronic sensor of which the sensing surface is fixed to the innersurface of the pipe.4.2 Test procedure4.2.1 Transverse distribution testNOTEThis test applies to the testing of the spreading device of a complete machine or of spreading devices alone.4.2.1.1When testing the spreading device for broadcasting, the containers shall be placed with their edgesparallel to the ground surface so that they are perpendicular to the line of travel of the machine and cover the totalthrowing width. In the case of a rearward throwing unit, the containers shall be placed so that the dividing linebetween the two containers in the middle coincides with the longitudinal vertical plane dividing the unit in twohalves.When testing the spreading device for band spreading the tested unit may be stationary with one container undereach outlet.NOTESpecial arrangements can be needed (e.g. an overpass for the wheels of the tanker on which the tested unit ismounted) in order to ensure that containers can be located in all positions.4.2.1.2All transverse distribution tests shall be performed when at least 10 % and at most 90 % of the originalmass of slurry to be filled in the tanker has been spread.4.2.1.3At least two tests shall be performed. Depending on the intended use of the tested unit according tothe instruction handbook, these tests shall, if possible, be performed at different settings of the flow. The settingsshall represent the full working range as specified by the manufacturer. In the case when only a spreading device isSIST EN 13406:2004
