ISO 22368-2:2004规定了两种试验方法，用于评估安装在用于作物保护的喷雾器上的清洁系统的性能，以清除喷雾器外表面上的沉积物。试验的目的是向喷雾器设计人员提供有关喷雾器污染的信息，并允许比较与外部清洁有关的不同附件或调整（试验A），并允许确定不同清洁装置的性能（试验B）。它适用于用于作物保护和液体肥料施用的安装式、牵引式和自行式农业喷雾器。

ISO 22368-2:2004 specifies two test methods for evaluating the performance of cleaning systems fitted onto sprayers used in crop protection for the removal of deposits on the external surfaces of the sprayer. The purpose of the tests is to provide sprayer designers with information on contamination of the sprayer and permit comparison of different attachments or adjustments in relation to external cleaning (Test A), and to allow the performance of different cleaning devices to be determined (Test B). It is applicable to mounted, trailed and self-propelled agricultural sprayers used for crop protection and liquid fertilizer applications.
