Abstract

ISO 29463-4:2011 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. ISO 29463-4:2011 also describes the other normative methods: the oil thread leak test and the photometer leak test, applicable to classes ISO 35 H to ISO 45 H HEPA filters, and the leak test with solid PSL aerosol. ISO 29463-4:2011 is intended for use in conjunction with ISO 29463-1, ISO 29463-2, ISO 29463-3 and ISO 29463-5.
