ISO 19932-2:2013
Equipment for crop protection — Knapsack sprayers — Part 2: Test methods
ISO 19932-2:2013 specifies test methods for the verification of requirements of ISO 19932-1:2013 for knapsack sprayers carried on the back or shoulder of the operator for use with plant protection products.
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, with a nominal volume of more than 3 l for their intended use primarily in agriculture and horticulture.
It does not apply to knapsack mistblowers according to ISO 28139.
