本文件建立并规定了统一的试验程序、条件、设备和性能报告，以便对空气滤清器的实验室性能进行直接比较。 最令人感兴趣的基本性能特征是气流限制或压差、除尘效率、灰尘容量和油浴式空气滤清器上的油残留。因此，本测试代码涉及这些参数的测量。 本文件适用于一般用于汽车和工业应用的内燃机和压缩机上使用的空气滤清器。

This document establishes and specifies uniform test procedures, conditions, equipment and a performance report to permit the direct laboratory performance comparison of air cleaners. The basic performance characteristics of greatest interest are air flow restriction or differential pressure, dust collection efficiency, dust capacity and oil carry-over on oil bath air cleaners. This test code therefore deals with the measurement of these parameters. This document is applicable to air cleaners used on internal combustion engines and compressors generally used in automotive and industrial applications.
