Equipment for crop protection — Methods for the laboratory measurement of spray drift — Wind tunnels ISO/PWI 22856

Scope

ISO 22856:2008 establishes general principles for the measurement of spray drift potential in wind tunnels under controlled laboratory conditions.
ISO 22856:2008 is applicable where comparative assessment or classification of the relative spray drift potential from spray generators (e.g. nozzles) or spray liquids is needed.
