UNE-EN ISO 28139:2021

This International Standard 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 air-blast sprayers as defined in ISO 5681.

NOTE 1 ISO 5681 is currently under revision.

NOTE 2 An example of this machine is given in Annex D.

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 International Standard deals with all significant hazards, hazardous situations and events, excepting those arising from vibration transmitted at the back of operator.

It is applicable to knapsack combustion engine-driven air-blast sprayers when they are used as intended and under the conditions foreseen 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 air-blast sprayers manufactured before the date of its publication.
