DIN EN ISO 17071:2011-12

The text of ISO 17071:2006 has been prepared by the "International Union of Leather Technologists and Chemists Societies" and has been adopted as EN ISO 17071:2011 by Technical Committee CEN/TC 289 "Leather", the secretariat of which is held by UNI (Italy). The responsible national committee is Working Committee NA 062-05-51 AA "Anforderungen und physikalische Prüfverfahren für Leder und seine Ausgangsprodukte" ("Requirements and physical test methods of leather and ..."), Mirror Committee of CEN/TC 289 "Leather" of the Materials Testing Standards Committee (NMP). This document replaces EN 14288:2003. This International Standard specifies two alternative methods for determining the fogging characteristics of leathers used in the passenger compartments of motor vehicles. These are two different test procedures to measure the volatile components and there is no mathematical correlation between the results obtained with Method A and those with Method B. Method A determines by reflection the light scattering properties (or opaqueness) and the nature of the film or droplet formation from volatile components condensed on a cold glass surface. Method B measures gravimetrically the quantity of volatile components condensed on a cold aluminium foil surface.
