DANSK DSF/FPREN ISO 19932-3 PDF

This Standard specifies the requirements and test methods for the inspection in use of Knapsack sprayers of over 3 litres nominal volume carried on the back or shoulder of the operator for applying Plant Protection Products (PPPs) in agriculture and horticulture. It is applicable to lever-operated knapsack sprayers, knapsack compression sprayers and knapsack sprayers driven by an engine or electric motor using hydraulic energy to atomise the spray liquid. The requirements relate mainly to the condition of the sprayer with respect to its potential risk to the operator and the environment and its performance to achieve good application. It does not apply to other portable equipment such as knapsack combustion engine-driven air blast sprayers/mistblowers (see ISO 10988 and ISO 28139), Controlled Droplet Application equipment utilising rotary atomisers, or portable application equipment for spatial application (e.g. foggers).
