标准范围

ISO 15873规定了差压文丘里型液体添加剂注入器的结构、操作要求和试验方法，该注入器是用于将化学品（包括液体肥料、水溶性肥料的液体溶液、酸、焦散剂、杀虫剂、除草剂和其他液体添加剂）注入灌溉系统的系统组成部分。ISO 15873未规定防止液体添加剂回流至饮用水供应系统的方法，在文丘里管注入器附近组装此类方法时，应遵守水保护法规。

ISO 15873 specifies the construction of, and operational requirements and test methods for, differential pressure Venturi-type liquid additive injectors -- a component of systems used to inject chemicals, including liquid fertilizers, liquid solutions of water-soluble fertilizers, acids, caustics, pesticides, herbicides and other liquid additives, into irrigation systems. ISO 15873 does not specify means of preventing backflow of liquid additives to potable water supply systems, the assembly of such means, near to the Venturi injector, being covered by water protection regulations.
