4 Description of component The tanks tested are designed for use with sprayers for the distribution of chemical products. They are made out of polyethylene, obtained via rotational moulding. There is a compartment in the front part of the tank to house the pump and tubing. On the, to the rear, are the seats for the machine s wheels. All models are equipped with auxiliary tanks for cleaning the distribution circuit and for hand washing. The circuit cleaning tank is positioned in the rear part, below the main tank, with the opening cap situated on the left. Liquid level in the main tank is displayed in the front right part and on the left via gauges, etched directly into the polyethylene. Access to the main tank is via 2 openings positioned on the left. The lower part of the main tank is shaped such a way as to facilitate emptying, even in an inclined position. Test method The functional parameters examined were the maximum capacity of the various tanks, the accuracy of content indicators of the main tank and the roughness of in and out surfaces. Values were calculated using water, free of suspended solids, and electronic scales. Results Capacity Main tank The maximum capacities measured close to the opening are given in the table below. Model max. capacity (l) difference vis-à-vis nominal value Linea TC % Linea TC , % Linea TC , % Linea TC , % All models had maximum capacities exceeding 5% of the nominal value, in keeping with the legal limit established for sprayers. 4/8

5 Circuit cleaning tank model Linea TC 600 Linea TC 1000 Linea TC 1500 Linea TC 2000 max. capacity (l) % vis-à-vis nominal value % % % % For the Linea TC 1500 and Linea TC 2000 models the capacity of the circuit cleaning tank is 10% lower than the nominal capacity of the main tank, thus the extent of the dilutable volume after the tank is installed in the sprayer will have to be checked. Hand washing tank The capacity of the hand washing tank, the same for all models, was 15.7 l. This value is above the legal minimum of 15 l. Gauge Tanks having a nominal capacity of up to 1,000 l are fitted with gauges having a scale in intervals of 50 l, while those having a higher capacity are in intervals of 100 l. For some models lower scale markings are not shown on the tank because of the rounded shape of the lower part of the tank. For each of these markings the manufacturer provides the indications (vertically from first marking etched in the polyethylene) needed to position them correctly on the frame of the finished machine. Up until 20% of nominal capacity, the maximum difference between the value indicated by the scale markings and the actual amount of liquid in the tank must be ±7.5% in accordance with reference legislation. For all the tanks to which the present test report refers, measured values were below the limit, as can be seen in the table below. model front indicator indicator Linea TC % -1.8% Linea TC % -3.0% Linea TC % -5.9% Linea TC % 4.5% Over 20% of nominal capacity, the maximum allowed difference is ±5.0%. Measured values are given in the table below. model front indicator indicator Linea TC % -4.1% Linea TC % 3.5% Linea TC % -4.4% Linea TC % 3.1% The graphs below show, for all tanks tested and for both content indicators (front and ), the differences (% error) between the value indicated by scale markings and the actual amount of liquid in the tank. 5/8

Measured values are given in the table below. model external roughness (Rz - µm) internal roughness (Rz - µm) Linea TC Linea TC Linea TC Linea TC Notes on results The tanks examined, designed for use with trailed sprayers, proved capable of meeting regulatory requirements. For some parameters, the installer must observe the recommendations made by the tank manufacturer in order to guarantee the above results for the end product, i.e. the sprayer. 7/8
