ISO/TC 142 "Cleaning equipment for air and other gases" Scope: Standardization in the fields

ISO/TC 142 "Cleaning equipment for air and other gases" Scope: Standardization in the fields of terminology, classification, characteristics, and test and performance methods for air and gas cleaning and disinfecting equipment for general ventilation and industrial applications. Excluded : • exhaust gas cleaners for gas turbines and IC engines in mobile equipment, this being within the scope of other ISO technical committees; • filters for personal protection equipment which are the field of work of technical committee ISO/TC 94; • cabin filters in mobile equipment covered by ISO/TC 22, 23 and 127. 23 rd April Paolo Tronville - NAFA 2010 Technical Seminar 4
