Frequently Asked Questions

ISO/TC 142/WG 4 is a Working Group within the International Organization for Standardization (ISO). It is named "HEPA and ULPA filters". This committee has published 4 standards.

ISO/TC 142/WG 4 develops ISO standards in the area of Information technology. Currently, there are 4 published standards from this working group.

The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.

A Working Group in ISO is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.

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.

Test method to measure the efficiency of air filtration media against spherical nanomaterials - Part 2: Size range from 3 nm to 30 nm

This document specifies the testing instruments and procedure for determining the filtration efficiencies of flat sheet filter media against airborne nanoparticles in the range of 3 nm to 30 nm. The testing methods in this document are limited to spherical or nearly-spherical particles to avoid uncertainties due to the particle shape.

Test method to measure the efficiency of air filtration media against spherical nanomaterials - Part 1: Size range from 20 nm to 500 nm

This document specifies the testing instruments and procedure for determining the fractional filtration efficiencies of flat sheet filter medium against airborne nanoparticles in the range of 20 nm to 500 nm. The testing methods in this document are limited to spherical or nearly-spherical particles to avoid uncertainties due to the particle shape.

ISO 29463-1:2017(Main)
High efficiency filters and filter media for removing particles from air - Part 1: Classification, performance, testing and marking

ISO 29463-1 establishes a classification of filters based on their performance, as determined in accordance with ISO 29463‑3, ISO 29463‑4 and ISO 29463‑5. It also provides an overview of the test procedures, and specifies general requirements for assessing and marking the filters, as well as for documenting the test results. It is intended to be used in conjunction with ISO 29463‑2, ISO 29463‑3, ISO 29463‑4 and ISO 29463‑5.
