HEPA Filter Test Standards

This Recommended Practice (RP) covers definitions, equipment, and procedures for leak testing high-efficiency particulate air (HEPA) filters and ultralow-penetration air (ULPA) filters in the factory as they are produced, at the job site before they are installed, and...

This Recommended Practice (RP) discusses test methods for physical and filtration properties of high-efficiency particulate air (HEPA) and ultra-low penetration air (ULPA) filtration media. Application of this RP is by mutual agreement between the customer and the supplier. Use of...

This European Standard applies to high efficiency particulate air filters and ultra low penetration air filters (EPA, HEPA and ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for applications in clean room technology or...

SCOPE AND LIMITATIONS This Recommended Practice (RP) covers basic provisions for HEPA (high efficiency particulate air) and ULPA (ultra-low penetration air) filter units as a basis for agreement between customers and suppliers. Filters that meet the requirements of this RP are...

ISO 29463-4:2011 specifies the test procedure of the "scan method", considered to be the reference method, for determining the leakage of filter elements. It is applicable to filters ranging from classes ISO 35 H to ISO 75 U. ISO 29463-4:2011 also describes the other normative...
