本文件规定了一般试验要求、试验装置和设备、试验材料、试验程序和报告，以确定旋转机械（如固定式燃气轮机、压缩机和其他固定式内燃机）进气过滤器系统中使用的空气过滤器元件的耐水性能。 该试验评估了空气过滤器元件在实验室条件下的耐水性能。根据本文件获得的性能结果不能（自行）定量地用于预测耐水性和寿命方面的使用性能。

This document specifies general test requirements, the test rig and equipment, the test materials and the test procedure and report for determining water endurance performance of air filter elements used in air intake filter systems for rotary machinery such as stationary gas turbines, compressors and other stationary internal combustion engines. The test evaluates water endurance performance of air filter elements under laboratory conditions. The performance results obtained in accordance with this document cannot be quantitatively applied (by themselves) to predict performance in service with regard to water endurance and lifetime.
