scope:

This document provides the general requirements associated with the specific characteristics of HEPA filters used in nuclear facilities with special performances described in the ISO 23137 series.

This document applies only for the filters used for nuclear HVAC containment 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 defined in the standard series (e.g. fire, high radioactive challenge, etc.).

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. Nevertheless, the specificities of process ventilation system protecting the workers inside the facilities will be specified by another part of the ISO 23137 series.

This part provides general requirements for the performance, design, construction, acceptance testing, and quality assurance for High Efficiency Particulate Air (HEPA) filters used in nuclear facilities. This document does not provide the specific conditions against which the nuclear filters are designed, tested and qualified.

The design, fabrication, inspection and testing, certificates with regards to their expected performances are mentioned.

Filter housing qualification will be addressed separately.
