Purpose and Scope
This Standard defines droplet spectrum categories for the classification of spray nozzles, relative to specified reference fan nozzles discharging spray into static air or so that no stream of air enhances atomization. The purpose of classification is to provide the nozzle user with droplet size information primarily to indicate off-site spray drift potential and secondarily for application efficacy.
This Standard defines a means for relative nozzle comparisons only based on droplet size. Other spray drift and application efficacy factors, such as droplet discharge trajectory, height, and velocity, air bubble inclusion; droplet evaporation; and impaction on target are examples of factors not addressed by the current Standard.
