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.

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.
