NF ISO 23137-1, X44-114 (04/2024)

This document provides general requirements associated with the specific characteristics of very high efficiency air (HEPA) filters used in nuclear installations. This document provides the manufacturer with general requirements for the performance, design, construction, acceptance testing, and quality assurance of HEPA filters used in nuclear facilities (for qualification and production testing). All types of HEPA filters used in these types of applications are covered, from large HEPA filters in HVAC exhaust systems to small, low flow cylindrical HEPA filters for glove boxes. Design, manufacturing, inspection and testing, certificates relating to their expected performance are mentioned. This document does not provide the specific conditions under which nuclear filters are designed, tested and qualified. This document only applies to filters used for nuclear heating, ventilation and air conditioning (HVAC) or control room habitability applications or applications related to exposure to radioactive ionizing radiation (e.g. medical or radioactive aerosol applications) under severe conditions (e.g. fire, highly radioactive testing, etc.). The qualification of the filter envelope is not part of this document.
