Droplet size adjustment 
Drift risks are very much related to the level of pulverization of liquid: droplets smaller than 100 µm are more prone to drift and it is important that during the application the fraction of very fine droplets is contained as much as possible. There are essentially two ways through which act in order to adjust the droplet size: the modification of the operating pressure (but this implies a consequent variation in the nozzles flow rate and therefore on the volume rate applied) or the change of nozzle.

Operational leakage protection

  1. Antidrip device 
    ==== Reference Standards ====
**EN 12761-3,   clause 4.1.4   EN 13790-2    clause 4.8.3**
==== Performance criteria ====
EN 12761-3: When the spraying stop control has been activated, the dripping shall not exceed 2 ml per nozzle during 5 min.
The measuring is started 8 s after the flow has been shut off.
EN 13790-2: After being switched off, the nozzles shall not drip. 5 s after the spray jet has collapsed there shall be
no dripping.

  2. Tank lid 
    ==== Reference Standards ====
**EN 12761-3          ISO 4254-6     5.4.2**
==== Performance criteria ====
The lid shall be:
- attached to the machine, e.g. by means of a chain;
- fitted with a holding device ensuring a closed position either by means of a positive mechanical action or
lids fixed by screwing;
- fitted so as to prevent leakage of the spray mixture, e.g. by means of a seal.

Dead volume protection 
To minimise the amount of the not dilutable volume (indicated also as dead volume) in a sprayer is useful in order to limit risks of environmental pollution at the end of the application. The dead volume, according to standard ISO 13440:1996, clause 2.3 is the “part of the total residual volume “ that cannot flow back to the tank during normal operation of the sprayer”. It is mainly the volume of liquid that remains in the delivery hoses between the pump and the nozzles.

  2. Draining capability 
    ==== Reference Standards ====
**ISO 4254-6**
==== Performance criteria ====
An emptying device in accordance with 4.5.3 of EN 907:1997 shall allow the complete emptying of the residual in the tank when the sprayer is in a horizontal position. Complete emptying of the residual is achieved if there are no visible puddles at the bottom of the tank after 5 min drainage.
