本文件规定了测试灌溉用旋转喷头耐久性的条件和方法。 此处使用的术语“洒水车”具有广义的通用含义，旨在涵盖ISO 15886-1中分类的各种产品，该标准适用于制造商定义的所有在运行期间同时具有静态部件和移动部件的洒水车分类。 对于任何给定的喷头，各种各样的喷头配置、操作条件和调整至少在理论上需要相应的大量测试。测试机构和制造商可以使用插值技术来减少实际测试运行的次数，前提是仍然满足精度标准。

This document specifies the conditions and methods for testing the durability of rotating sprinklers for irrigation. The term sprinkler is used here in a broad generic sense and is meant to cover a wide variety of products as classified in ISO 15886-1, which applies to all irrigation sprinkler classifications having both static parts and moving parts during operation, as defined by the manufacturer. For any given sprinkler, a wide range of nozzle configurations, operating conditions, and adjustments generates at least a theoretical need for a correspondingly large number of tests. Testing agencies and manufacturers can use interpolation techniques to reduce the number of actual test runs, provided accuracy standards are still being met.
