1 Scope

This standard specifies the technical requirements and tests for knapsack air (two-phase flow) sprayers and air-assisted centrifugal sprayers (see ISO 5681 definition)

Methods and minimum performance limits:

This standard applies to knapsack power sprayers equipped with engines and carried by operators, mainly used in agriculture and gardening (hereinafter referred to as

For the sprayer):

This standard does not apply to hydraulic sprayers, thermal sprayers, and room temperature fog machines, nor does it apply to sprayers that spray dry matter:

This standard relates to the sprayer's droplet deposition potential under general technical conditions and specified conditions: This standard does not include

For the safety content and safety requirements of the fog machine, see ISO 28139:
