# Council Regulation (EC) No 428/2009 of 5 May 2009 setting up a Community regime for the control of exports, transfer, brokering and transit of dual-use items (Recast), Division [9A350]: Spraying or fogging systems, specially designed or modified for fitting to aircraft, "lighter-than-air vehicles" or “Unmanned Aerial Vehicles” (“UAVs”), and specially designed components therefor, as follows:


a..Complete spraying or fogging systems capable of delivering, from a liquid suspension, an initial droplet ‘VMD’ of less than 50 μm at a flow rate of greater than two litres per minute;
b..Spray booms or arrays of aerosol generating units capable of delivering, from a liquid suspension, an initial droplet ‘VMD’ of less than 50 μm at a flow rate of greater than two litres per minute;
c..Aerosol generating units specially designed for fitting to systems specified in 9A350.a. and.b.
Note:
Aerosol generating units are devices specially designed or modified for fitting to aircraft such as nozzles, rotary drum atomizers and similar devices.
Note:
9A350 does not control spraying or fogging systems and components that are demonstrated not to be capable of delivering biological agents in the form of infectious aerosols.
Technical Notes:
1.
Droplet size for spray equipment or nozzles specially designed for use on aircraft, "lighter-than-air vehicles" or unmanned aerial vehicles should be measured using either of the following:
a..Doppler laser method;
b..Forward laser diffraction method.
2.
In 9A350 ‘VMD’ means Volume Median Diameter and for water-based systems this equates to Mass Median Diameter (MMD).
