ISO 29463-5:2011 specifies the reference test procedure for determining the efficiency of filters at their most penetrating particle size (MPPS). ISO 29463-5:2011 also gives guidelines for the testing and classification for filters with an MPPS of less than 0,1 μm and filters...
This document specifies construction requirements and test methods for pressurized granulated media filters, hereinafter referred to as media filters, intended for operation in agricultural irrigation systems. It is applicable to both manual cleaning media...
This International Standard specifies a standard reference test method for the comparative characterization of pulse-jet cleanable filter media, to be used in filter elements (e.g. bag filters, pocket filters, cartridge filters) applied in dry gas cleaning...
This International Standard presents a test method for the comparative characterization of pulse-jet cleanable filter media, to be used in filter elements (e.g. bag filters, pocket filters, cartridge filters) applied in dry gas cleaning under standardized...
5.1 The air-flow resistance (pressure drop) of a filter is an important parameter that can assist in characterizing the physical make-up as well as the utility of a filter. 5.2 Therefore, flow characteristics of clean filter media can be used for quality control, product...
Introduction The definition of filtration contains the word medium. This medium can be granular (e.g., sand or coal) or it can be composed of synthetic material (membranes). This book focuses on the evaluation of granular filter media. By definition, filtration does not seem...
This test method is designed to evaluate qualitatively the presence of antibacterial and antifungal activity in or on fabrics or air filter media. Use half-strength (nutrient and agar) tryptic soy agar as the inoculum vehicle for bacteria and half-strength potato dextrose agar as the...
This test method determines the comparative performance of filter media. The results can be used for design, manufacturing, construction and selection of filter media. Results obtained by this test method should not be used to predict absolute performance on full scale...
This document 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,...
This International Standard specifies the sampling method of fabric filter media from filter system in operation and test method thereof to evaluate the degradation of filter media for dry type filtering dust collector (hereafter referred to as "bag...
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...
This European Standard applies to high efficiency particulate air filters and ultra low penetration air filters (EPA, HEPA and ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for applications in clean room technology or pharmaceutical...
1.1 This test method covers a procedure for determining the filterability of aviation turbine fuels (for other middle distillate fuels, see Test Method D6426). Note 1: ASTM specification fuels falling within the scope of this test method are Specifications D1655 and D6615 and the military...
