This method describes the protocol for testing a portable rotary atomizer sprayer consisting of a spinning atomizer (usually a disc or cup) onto which spray liquid flows to produce spray droplets. The atomizer is driven by a small electric motor that can be powered through a DC source using batteries. The sprayer can be carried within the carrying handle, on the operator’s belt, or on a strap slung over the operator’s shoulder, depending on the use. Spray liquid flows onto the atomizer by gravity from a small bottle mounted on the spray head, from a backpack, or from a shoulder-slung tank.

Kijani Testing developed the testing protocol with CLASP in support of VeraSol, a quality assurance program for off-grid solar solutions.
