High-efficiency filters and filter media for removing particles in air - Test method for determining leakage of filter elements. Scan method algolia-ignore This document describes a testWhat is this standard about? This part of ISO 29463 specifies the test procedure of the scan method, considered to be the reference method, for determining the leakage of filter elements. It is applicable to filters ranging from classes ISO 35 H to ISO 75 U. It also describes the other normative methods, the oil thread leak test (see Annex A) and the photometer leak test (see Annex B), applicable to classes ISO 35 H to ISO 45 H HEPA filters, and the
