ISO/TC 23/SC 6/WG 18 - Test methods for nozzles and sprayers

ISO 5682-2:2017 is applicable for sprayers intended to apply liquid over a horizontal surface. ISO 5682-2:2017 specifies test methods to assess sprayed liquid horizontal transverse distribution. Methods are based on sprayed liquid volume measurement, nozzle flow rate measurement or nozzle tip pressure measurement. ISO 5682-2:2017 does not cover aerial sprayers. Hydraulic sprayers use a range of design features to deliver and control spray. The test methods provided in this document are all useful but don't give the same information. They are complementary. Some test methods are not suitable for all sprayer types. Applicable test methods are described in an informative annex.

ISO 5682-1:2017 specifies test methods to assess the performance of sprayer nozzles with the exception of droplet characteristics. Applicable tests by nozzle type are described in an informative annex as a guide, but this is not required for use of this document.

ISO 5682-3:2017 specifies the test method to assess the performance of volume/area adjustment systems for spray systems. ISO 5682-3:2017 is not applicable for manually-operated knapsack sprayers or for aircraft sprayers.
