BS ISO 22856:2008 Equipment for crop protection. Methods for the laboratory measurement of spray drift. Wind tunnels

BS ISO 22856 establishes general principles for the measurement of spray drift potential in wind tunnels under controlled laboratory conditions.

BS ISO 22856 is applicable where comparative assessment or classification of the relative spray drift potential from spray generators (e.g. nozzles) or spray liquids is needed.
