ISO DIS 19932-3

Description / Abstract: This part of ISO 19932 specifies the requirements and test methods for the inspection in use of Knapsack sprayers carried on the back or shoulder of the operator for use with Plant Protection Products (PPPs).

It is applicable to lever-operated knapsack sprayers, knapsack compression sprayers and knapsack sprayers driven by an engine or electric motor using hydraulic pressure atomisation of the spray liquid, intended for use primarily in agriculture, forestry and horticulture, with a nominal volume of more than 6.0 l.

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 knapsack combustion engine-driven air-blast sprayers according to ISO/DIS 28139, Controlled Droplet Application equipment utilising rotary atomisers, or portable application equipment for spatial application (e.g. foggers).
