ISO/TC 23/SC 6/WG 5 - Portable sprayers

This document specifies safety requirements and their verification, environmental requirements and related test methods, and minimum performance limits, for the design and construction of knapsack combustion engine-driven airblast sprayers as defined in 3.9. It describes methods for the elimination or reduction of hazards arising from their use. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. It addresses general operating parameters as well as the potential deposition of spray droplets under specified controlled conditions. This document deals with all significant hazards, hazardous situations and events, excepting those arising from vibration transmitted to the back of the operator. It is applicable to knapsack combustion engine-driven airblast sprayers when they are used as intended and under the conditions foreseeable by the manufacturer (see Table A.1). It is not applicable to: — hydraulic pressure sprayers; — thermal sprayers; — cold foggers; — sprayers adapted for the application of dry material. It is not applicable to knapsack combustion engine-driven airblast sprayers manufactured before the date of its publication. The requirements of this document applies to products manufactured 18 months after publication.

ISO 19932-1:2013 specifies the safety and environmental requirements and their means of verification for the design and construction of knapsack sprayers carried on the back or shoulder of the operator for use with plant protection products. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. 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. ISO 19932-1:2013 deals with all significant hazards, hazardous situations and hazardous events relevant to knapsack sprayers when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer, excepting the hazards arising from: static electricity; explosion or fire from chemicals for spraying; and insufficient structural integrity. ISO 19932-1:2013 is not applicable to knapsack sprayers which are manufactured before the date of its publication.

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.
