标准范围

ISO 13457:2008规定了用于将化学品注入灌溉系统的水驱动化学喷射泵的结构、操作要求和试验方法。这些化学品包括液体肥料、肥料溶液和其他可溶性农业化学品，如酸和农药。ISO 13457:2008适用于那些计划在水温高达50°C的条件下运行的泵，以及灌溉中常规使用的化学品类型和浓度。它不包括防回流装置的功能，也不适用于水-根据文丘里原理将化学物质注入灌溉系统的驱动装置。

ISO 13457:2008 specifies the construction, operational requirements and test methods for water？driven chemical injector pumps, used to inject chemicals into irrigation systems. The chemicals include liquid fertilizers and solutions of fertilizers and other soluble agricultural chemicals such as acids and pesticides.ISO 13457:2008 is applicable to those pumps intended to operate at water temperatures of up to 50 °C and with the types and concentrations of chemicals routinely applied in irrigation.It does not cover the function of backflow prevention devices, nor is it applicable to water-driven devices for injecting chemicals into an irrigation system operating on the basis of the Venturi principle.
