The methods and requirements aim at evaluating the manure spreaders regarding the user's ability, when he uses the machine according to the manufacturer instruction handbook, to: control the application rate; attain an even distribution of the manure; reduce the load on the external environment, for example by not unintentionally spreading manure outside the target area. It should be noted that there is often a great number of varieties of a machine type. This should be considered when selecting the machine configuration for the tests, with the aim of reducing the necessary number of machines to be tested.

It specifies requirements for the transverse and longitudinal spreading characteristics such as working widths, characteristic application rate, characteristic flow, the stretch within the tolerance zone and the coefficient of variation for the longitudinal spreading. These requirements are valid only according to the tests with manure as described in Table A.1. This standard is not applicable to manure band-spreaders or to sludge spreaders. NOTESludge spreaders can be dealt with in a future revision when there is sufficient data available to determine their classification and to set the limits for the machine requirements. Personal safety aspects have not been considered in this standard. These aspects are covered by EN 690. 2 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 2.1 manure spreader machine for transporting and spreading manure on the field surface 2.2 manure band-spreader manure spreader which spreads the manure in bands separated by bands with no manure 2.3 sludge spreader machine for transporting and spreading sludge on the field surface 2.4 working width distance between the centre of two adjacent bouts 2.5 throwing width distance between the left and the right end of a transverse distribution 2.6 mass of manure spread mass of manure spread between the start of the test and the end of the test when the flow is less than 1kg/s during 5 s or when no mass change of 10 kg is registered during 10 s 2.7 unloading time time needed to empty the first 95 % of the mass of manure spread 2.8 characteristic flow average flow calculated over a specified part of the unloading time Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 01:39:45 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13080:2002 (E) 6 2.9 characteristic application rate application rate calculated on the basis of characteristic flow, working width and forward speed 2.10 tolerance zone interval of flows within 15 % and + 15 % of the characteristic flow 2.11 stretch within the tolerance zone percentage of the unloading time during which the momentary flows lie within the tolerance zone 2.12 unidirectional distribution distribution obtained when the manure spreader moves for two adjacent bouts in the same direction 2.13 “to and fro“ distribution distribution obtained when the manure spreader moves for two adjacent bouts in opposite direction 3 Requirements 3.1 General The requirements in this standard are based on the selection of manure for the tests as described in 4.1.3. The requirements shall be met for manure with different bulk density and dry matter content based on the declaration from the machine manufacturer concerning the manure that the machine can handle. 3.2 Transverse distribution - Working widths The machine shall, for a specific setting, have at least one working width so that the coefficient of variation (CV) is lower than 30 % and wider than the half of the throwing width, but at least equal to the width of the machine frame when simulating unidirectional distribution and/or “to and fro“ distribution The CV shall be calculated according to 4.3.1 and the throwing width shall be limited to the total width of adjacent collecting containers as far as the container which is adjacent to three adjacent containers containing less than 50 g of manure. The requirement shall be fulfilled for two flow settings: low and high corresponding to the application rate indicated in 3.3.1. If the requirement is not met for one of the settings, one additional test shall be completed with the same setting and with manure selected as specified in 4.1.3 to check the lack of temporary default; this shall be noted in the test report. To fulfil the complete requirements the machine shall fulfil the requirement for the setting at which the retest was completed. 3.3 Longitudinal distribution 3.3.1 Characteristic application rate Unless otherwise specified by the manufacturer, the characteristic application rates that can be obtained shall cover at least the interval 1 kg/m2 (10 t/ha) to 4 kg/m2 (40 t/ha) when calculated in accordance with 4.3.2. 3.3.2 Stretch within the tolerance zone The stretch within the tolerance zone determined at a specific setting shall exceed 35 % of the unloading time.

The requirement shall be fulfilled for two settings: low and high. If the requirement is not met for one of the settings, one additional test shall be completed with the same setting and with manure selected as specified in 4.1.3. to check the lack of temporary default; this shall be noted in the test report. To fulfil the complete requirements the machine shall fulfil the requirement for the setting at which the retest was completed. 3.3.3 Coefficient of variation The coefficient of variation (CV), determined at a specific setting, shall be less than 40 %. The calculation of the CV shall be done according to 4.3.4, before overlapping. The requirement shall be fulfilled for two settings: low and high. If the requirement is not met for one of the settings, one additional test shall be completed with the same setting and with manure selected as specified in 4.1.3. to check the lack of temporary default, this shall be noted in the test report. To fulfil the complete requirements the machine shall fulfil the requirement for the setting at which the retest was completed. 3.3.4 Optimum overlapping The optimum overlapping in the longitudinal distribution shall be given in the instruction handbook. The overlapping shall be determined in accordance with 4.3.5 and calculated for forward speeds of 3 km/h and 8 km/h respectively. 4 Verification 4.1 Test conditions 4.1.1 Manure spreader The machine shall be used in accordance with the instructions given in the instruction handbook. If the instructions limit the use of the machine, in relation to 4.1.3, this shall be noted in the test report. 4.1.2 Manure The manure is classified in four classes as described in annex A. The physical properties of the manure used in the tests shall be determined in accordance with annex A and shall be stated in the test report. The manure that is to be used for the tests shall have been handled as little as possible prior to the test. Manure that has passed through a spreader shall not be reused. If the machine is to be tested against the requirements in clause 3, the tests shall be completed with manure from different classes as described in 4.1.3. 4.1.3 Selection of manure For the verification of the requirements in clause 3, manure defined and handled in accordance with 4.1.2 shall be used. The number of manure classes shall be selected in accordance with Table 1.

If a loader with a bucket is used for loading, the bucket shall not be wider than 1/2 the length of the machines body. The bucket shall be emptied by tipping at a height which does not exceed the height of the body by more than 1 m. The manure shall be levelled out manually so that the surface of the manure is even with the upper edge of the body. The manure shall not be artificially compressed. 4.1.5 Test site and ambient conditions The tests shall be carried out on an even, horizontal surface, indoors or outdoors, and with the driving direction of the machine oriented as far as possible against the direction of the wind. During the transverse distribution tests, the wind velocity shall not exceed 3 m/s, measured 1,5 m above ground level with a l
