BS EN 13739-2:2011 pdf download – Agricultural machinery — Solid fertilizer broadcasters and full width distributors — Environmental protection Part 2: Test methods Transverse test  Devices for receiving fertilizer for transverse distribution The collecting containers shall have top external dimensions of 500 mm × 500 mm and precautions shall be taken to minimise spillage by ricochet out of the containers. NOTE The wall thickness at the top edge should be equal or smaller than 1,5 mm. An example of a funnel shaped container is shown in Figure B.1. The container can also be a rectangular or square vertical section. Test collecting containers with external top dimensions of 250 mm x 500 mm could be used side by side if their collected amount is added together. Existing collecting containers of 250 mm x 1000 mm could be used since it has been shown that the result corresponds to 500 mm x 500 mm containers. 90 % to 110 % of the expected amount of test material shall be collected. This requirement is checked by comparing the application rate calculated from the collecting containers with the application rate obtained in the flow rate test, when using test material from the same batch in both measurements. 5.3 Rotating test 5.3.1 Measurement of the angular position of the spreader The measurement of the angular position between the row of collecting containers and the spreader axis shall be done with a sensor. The precision of this angle measurement shall be better than 0,1°. 5.3.2 Data acquisition device The angular position of the spreader, the fertilizer mass into the spreader hopper, the fertiliser mass into each of the collecting containers, and the acquisition and storage time shall be measured and registered with a frequency higher or equal to 5 Hz. The response time of the measurement devices should be at least 0,2 s. Data shall be filtered with a Bessel lowpass at 0,5 Hz. 5.3.3 Devices for receiving fertilizer for spread pattern distribution The collecting containers shall have top external dimensions of 500 mm × 500 mm and precautions shall be taken to minimise spillage by ricochet out of the containers. NOTE The wall thickness at the top edge should be equal or smaller than 1,5 mm. An example of a funnel shaped container is shown in Figure B.1. The rotation axis of the rotating carrier shall be located on the axis between the containers...
