Run the spreading test with the open position that has been decided on for
operation:
Forward speed: 3 to 4 km/h.
Open the metering slide 10 m in front of the collecting vessels.
Close the metering slides approx. 30 m behind the collecting vessels.
8.5.3 Running three passages
Layout:
Width of testing area: 3 x tramline distance
Length of testing area: 60 to 70 m
The three tracks must be parallel. If you are running the test without drilled
tramlines, the paths must be measured using a tape measure and marked
(e.g. with rods).
Figure 8.14: Layout for three passages
NOTICE
If the quantity collected in the collecting vessels is insufficient, repeat the pas-
sage.
Do not change the adjustment of the metering slides.
NOTICE
We recommend the layout plan up to a spreading width of 24 m. A layout plan
for greater working widths is attached to the PPS5 practise test kit.
