  1. 2010 NAFA Technical Seminar ● April 21 - 23 , 2010Louisville, KY International standardization activity related to air cleaning equipment The Galt House Hotel, April 23rd 2010 Track Two "What's new: International Standardization" 11:45-12:15 Paolo Tronville Politecnico di Torino Italy

  2. Background • Standards-writing organizations have been developing “regional” air filtration standards for more than 50 years • ASHRAE and IEST have been providing air filter test methods and ratings for the US market and beyond • Globalization and new emerging markets represent a new challenge for leading organizations like ASHRAE, CEN, … • ISO (International Organization for Standardization) was founded in 1946 and develops International Standards • 156 national bodies and 580 organizations in liaison • ISO is the clear leader for the production of International Standards: about 200 Technical Committees (TC) at work Paolo Tronville - NAFA 2010 Technical Seminar

  3. Member Country SC TC Secretariat ISO Experts Member Country TAG WG How Does It Happen? Paolo Tronville - NAFA 2010 Technical Seminar

  4. ISO/TC142"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. Paolo Tronville - NAFA 2010 Technical Seminar

  5. History of ISO/TC142 • Created in 1970 (French Secretariat) • Published 2 documents • ISO 3649 – Vocabulary • ISO 6584 – Classification of Dust Separators • Put in stand-by in May 1976 (USA was not participating) • Re-activated in 2005 • Secretariat: UNI (Italy) • Secretary: Anna Martino (martino@cti2000.it) • Chairman: Paolo Tronville (paolo.tronville@polito.it) … volunteers welcome to apply for the position! Paolo Tronville - NAFA 2010 Technical Seminar

  6. ISO/TC142 current structure 16 P-members (participating countries), about 100 experts • WG 1 "Terminology" (John Dyment, UK) • WG 2 "UV-C technology" (Peter Beale, Steril-Aire, USA) • WG 3 "General ventilation filters" (Don Thornburg, Camfil Farr, USA) • WG 4 "HEPA and ULPA filters" (R. Vijayakumar, USA) • WG 5 "Dust collectors, droplet separators and purifiers" (Bruce McDonald, USA) • WG 8 "Gas-phase air cleaning devices" (Mikael Forslund, Camfil Farr, Sweden) • WG 9 "Particulate air filter intake systems for rotary machinery and stationary internal combustion engines" (Ulf Johansson, Camfil Farr, Sweden) • JWG "Aerosol filters for nuclear applications" (Pierre Cortes, ITER, France) Paolo Tronville - NAFA 2010 Technical Seminar

  7. Stages leading to a new standard After a New Work Item Proposal has been approved the clock starts running: the work must be completed in 24, 36 (usually) or 48 months. Paolo Tronville - NAFA 2010 Technical Seminar
