ISO 23137-1:2024

This document provides the general requirements associated with the specific characteristics of high efficiency particulate air (HEPA) filters used in nuclear facilities. This document provides the manufacturer with general requirements for the performance, design, construction, acceptance testing and quality assurance for HEPA filters used in nuclear facilities (for qualification and production tests). All types of HEPA filter used in such applications are covered, from the large size HEPA filters in exhaust HVAC systems to small size low flow rate cylindrical HEPA filters for glove boxes. The design, fabrication, inspection and testing, certificates with regards to their expected performances are mentioned. This document does not provide the specific conditions against which the nuclear filters are designed, tested and qualified. This document applies only to the filters used for nuclear heating ventilation air conditioning (HVAC) or control rooms habitability applications or applications related to the exposure to radioactive ionizing radiations (e.g. medical or radioactive aerosols applications) in the severe conditions (e.g. fire, high radioactive challenge). Filter housing qualification is not part of this document.
