ISO 17597:2026

OVERVIEW

This document specifies a method that evaluates inactivation/removal effectiveness against airborne microorganisms in air cleaning devices. This method includes detailed requirements for the test rig, and simulates the air flowrate of the devices. The method also covers data acquisition, analysis, and reporting of results. Additionally, this document provides a normative procedure (see Annex A) for determining the effect of dust loading on the inactivation and removal effectiveness.

This document is applicable to in-duct air cleaning devices, such as air filters set up in a heating, ventilation and air-conditioning (HVAC) system in commercial, institutional and office buildings, also in-duct air-purifying systems, or air sterilizers in these buildings. It applies to testing conducted under controlled laboratory conditions using specific surrogate test microorganisms (bacteria, moulds and viruses).

This document does not apply to

• air cleaning devices intended for portable or standalone room use, which are addressed by ISO 16000-36 and the IEC 63086 series,
• devices evaluated solely for the physical removal of non-biological particulate matter, which are covered by the ISO 16890 series, and
• clinical, medical or industrial cleanroom applications requiring specific pathogenic testing.

Furthermore, it does not cover the detailed assessment of ultraviolet (UV) dose evaluation exclusively for in-duct ultraviolet germicidal irradiation (UVGI) devices, which is covered by ISO 15714 and ASHRAE 185.1.
