High efficiency particulate air filters (HEPA and ULPA) - Part 5 : determining the efficiency of filter element

Le présent document constitue la partie 5 d'une norme en 6 parties qui définit une méthode de détermination de l'efficacité des filtres HEPA et ULPA à partir d'une méthode de comptage de particules, au moyen d'un aérosol d'essai liquide et permet de classer les filtres de façon normalisée, en fonction de leur efficacité. Le présent document concerne la mesure de l'efficacité des éléments filtrants. Il donne les conditions, procédures d'essai, un exemple de circuit d'essai ainsi que la méthode d'évaluation des résultats d'essai.

High-efficiency filters and filter media for removing particles in air - Part 5 : test method for filter elements

This document specifies the test methods for determining the efficiency of filters at their most penetrating particle size (MPPS). It also gives guidelines for the testing and classification for filters with an MPPS of less than 0,1 μm (Annex B) and filters using media with (charged) synthetic fibres (Annex C). It is intended for use in conjunction with ISO 29463‑1, ISO 29463‑2, ISO 29463‑3 and ISO 29463‑4.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

  • mandatory clauses to satisfy,
  • non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
