High efficiency particulate air (HEPA) filters — Classification, construction and performance

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.
