规定了全一次性高效微粒空气（HEPA）过滤器的分类、结构和性能测试要求。它包括被称为超低渗透空气（ULPA）过滤器的过滤器，但不包括中效颗粒空气过滤器（MEPA）。附录提供了结构强度测试的要求。

Specifies requirements for the classification, construction and performance testing of fully disposable high efficiency particulate air (HEPA) filters. It includes those filters known as ultra low penetration air (ULPA) filters but excludes medium efficiency particulate air filters (MEPA). An appendix provides requirements for structural strength testing.
