This International Standard specifies construction and operational requirements and test methods for water-driven chemical injector pumps, referred to hereinafter as water-driven injector pumps. These water-driven injector pumps are used to inject chemicals into irrigation systems. The chemicals include liquid fertilisers and solutions of fertilisers and other soluble agricultural chemicals such as acids, pesticides and herbicides.
This International Standard is applicable to water-driven injector pumps which are intended to operate at water temperatures of up to 50 ℃ and with the types and concentrations of chemicals routinely applied in irrigation. It is not applicable to backflow prevention devices (which are not an integral part of a water-driven injector pump), nor to Venturi-principle water-driven devices for injecting chemicals into an irrigation system.
