Air filters for general ventilationPartTechnical specifications, requirements and classification system based upon particulate matter eficiency (ePM) The ISO series describes the equipment, materials, technical specifications, requirements, qualifications and procedures to produce the laboratory performance ASHRAE and EN EN-ISO in brief. ISO (all parts) refers to particulate air filter elements for general ventilation having an ePMefficiency less than or equal to% when tested according to the procedures ISO establishes an efficiency classification system of air filters for general ventilation based upon particulate matter (PM). Instead of the previousfilter classes,should now realistically render information about the true effect of filters StepThe Filter is subjected to The ISO series describes the equipment, materials, technical specifications, requirements, qualifications and procedures to produce the laboratory performance data and efficiency classification ISO The new standard for classifying air filters. But from the beginning of, a new standard comes into force that completely changes the way that filters are tested and categorised ISO New Standard for Classiying Air Filters. For overyears EN has been the most used standard for classifying air fi lters for coarse and fi ne dust particles. As early as ember, the new air filter standard, ISO, has applied. It also provides an overview of the test In order to work towards testing ventilation filters in a manner that reflects the nature (and terminology) of PM pollution, ISO specifies that filter efficiencies will be calculated ISOFinalFree download as PDF File.pdf), Text File.txt) or read online for free. EN has been the most widely-used method of classifying air filters for overyears. The ISO standard consists of four different parts: Technical specifications, requirements and the classi In ember, the ISO standard became effective in order to globally regulate the various standards such as EN or ASHRAE Particularly affected are the StepTest procedure of the ISO standard begins with measuring the efficiency of an air filter at a particle size range of μm toμm. Under EN, the efi ciency of an air fi lter was assessed as an average value calculated by means of loading steps with a synthetic laboratory dust ISOFinalFree download as PDF File.pdf), Text File.txt) or read online for free.
