20、opy, (c) BSI EN 13406:2002 (E) 4 Introduction The objective of this standard is to specify test methods and requirements that, as far as possible, allow uniform testing and evaluation of slurry tankers. The methods and requirements aim at evaluating the slurry tankers and the spreading devices regar
21、ding the users ability, when he uses the machine according to the manufacturer instruction handbook, to: control the application rate; attain an even distribution of the slurry; reduce the load on the external environment, for example by not unintentionally spreading slurry outside the target area.
22、It should be noted that there is often a great number of varieties of a machine type and also varieties of spreading device. 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. This standard is deve
23、loped 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 pres
24、sure/flow measurements).

25、preading of slurry in agriculture and horticulture with the intention of minimising the environmental damage. It specifies requirements for the transverse and longitudinal spreading characteristics such as working widths, characteristic application rate, characteristic flow and the stretch within th
26、e tolerance zone. NOTEThe application of this standard alone will not be sufficient to deal with all the environmental aspects. Other aspects such as ammonia emission, odour reduction etc. should be considered. These requirements are valid only according to the tests with slurry as described in Tabl
27、e A.1. Personal safety aspects have not been considered in this standard. These aspects are covered by EN 707. 2 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 2.1 slurry tanker machine for handling, transporting and distributing slurry K

31、n the case of slurry tankers, this specified part equals 100 % of the unloading time, i.e. the characteristic flow will be equal to the average flow. 2.8 characteristic application rate application rate calculated on the basis of characteristic flow, working width and forward speed 2.9 tolerance zon

34、Transverse distribution 3.2.1 Broadcasting spreading devices Working widths The tested unit shall, for a specific setting, have at least one working width so that the coefficient of variation (CV) is lower than 20 % and wider than the half of the throwing width when simulating unidirectional distrib
35、ution and/or “to and fro“ distribution. The CV shall be calculated according to 4.3.1.1 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 slurry. The test sh
36、all be completed in accordance with 4.2.1 and the requirement shall be fulfilled for the settings of flows defined in 4.2.1.3 with slurry selected as specified in 4.1.2. If the requirement is not met for one of the settings, one additional test shall be completed with that same setting and with slur
37、ry selected as specified in 4.1.2 to check the lack of temporary default; this shall be noted in the test report. The calculated CV for this additional test shall then be lower than 20 %.

38、406:2002 (E) 7 3.2.2 Band spreading devices Average deviation NOTEThe method for the collection of slurry in the transverse tests (e.g. the size of the collecting containers), is different for band spreading devices than for broadcasting spreading devices. Therefore, it would be inappropriate to use
39、 the CV for describing the evenness of spreading for band spreading devices too, since that can lead to misleading comparisons of the evenness 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 %
40、. 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 flows defined in 4.2.1.3. If the requirement is not met for one of the settings, one additional test shall be completed wit
41、h that same setting and with slurry selected as specified in 4.1.2 to check the lack of temporary default; this shall be noted in the test report. The calculated averaged deviation for this additional test shall then be lower than 15 %. 3.3 Longitudinal distribution 3.3.1 Characteristic application
42、rate A test shall be made to check that it is possible to obtain the lowest characteristic application rate specified by the manufacturer, when the forward speed used is lower than 8 km/h. This characteristic application rate shall be stated in the test report. The test shall be made in accordance w
43、ith 4.2.2 and the calculation of the characteristic application rate shall be made 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 90 % of the unloading time. The test shall be made in accordance wi
44、th 4.2.2 and the calculation of the stretch within the tolerance zone shall be completed 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 setting and wi
45、th slurry selected as specified in 4.1.2 to check the lack of temporary default; this shall be noted in the test report. The calculated stretch within the tolerance zone for this additional test shall then be longer than 90 % of the unloading time. 4 Verification 4.1 Test conditions 4.1.1 Slurry tan
46、ker and spreading device The unit to be tested shall be used in accordance with the instructions given in the instruction handbook. If a slurry tanker is equipped with an agitation device, this device shall operate to avoid separation of the slurry. If the instructions limit the use of the unit, in
47、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 that allows slurry to be supplied from a separate pump (similar to an umbilical system). In all cases the mounting shall allow measure
48、ments of pressures and corresponding flows. When only the tanker (without spreading device) is tested, the tanker shall be connected to equipment that allows pressure/flow measurements to be performed at different backpressures of the spreading devices (for example through a variable valve).

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 with the information given by the manu
