Leather - Physical and mechanical tests - Determination of fogging characteristics (ISO 17071:2006)

ISO 17071:2006 specifies two alternative methods for determining the fogging characteristics of leathers used in the passenger compartments of motor vehicles, namely Method A and Method B. 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. Annex A gives the results of inter-laboratory trial which show that Method B performs well, whereas Method A showed a large variation in the percentage reflection.
The test conditions allow the two tests to be carried out in succession.

Leder - Physikalische und mechanische Prüfungen - Bestimmung der Fogging-Eigenschaften (ISO 17071:2006)

Diese Internationale Norm legt zwei alternative Verfahren, d. h. Verfahren A und Verfahren B, zur Bestimmung der Fogging Eigenschaften von Leder für den Fahrgastraum von Kraftfahrzeugen fest. Es handelt sich jedoch um zwei unterschiedliche Prüfverfahren zum Bestimmen der flüchtigen Bestandteile und es besteht keine mathematische Beziehung zwischen den nach Verfahren A und den nach Verfahren B erhaltenen Ergebnissen.
Bei Verfahren A werden durch Reflexion die Licht streuenden Eigenschaften (oder Opazität) und die Art der Film  oder Tröpfchenbildung aus an einer kalten Glasfläche kondensierten flüchtigen Bestandteilen bestimmt. Bei Verfahren B wird die an einer kalten Aluminiumfolie kondensierte Menge flüchtiger Bestandteile gravimetrisch bestimmt. Anhang A enthält die Ergebnisse eines Ringversuchs, die zeigen, dass Verfahren B gute Ergebnisse bringt, während Verfahren A eine große Abweichung in der prozentualen Reflexion aufweist.
Die Prüfbedingungen erlauben, dass beide Prüfungen nacheinander durchgeführt werden.

Cuir - Essais physiques et mécaniques - Détermination des caractéristiques de condensation (ISO 17071:2006)

L'ISO 17071:2006 spécifie deux méthodes différentes pour déterminer les caractéristiques de la condensation provoquée par les cuirs utilisés dans l'habitacle des véhicules automobiles, à savoir la Méthode A et la Méthode B. Il s'agit cependant de deux modes opératoires d'essai différents pour le mesurage des matières volatiles et il n'existe aucune corrélation mathématique entre les résultats obtenus avec la Méthode A et ceux obtenus avec la Méthode B.
La Méthode A détermine par réflexion les propriétés de dispersion de la lumière (ou l'opacité) et la nature de la formation du film ou des gouttelettes à partir de matières volatiles condensées sur une surface froide en verre. La Méthode B mesure par gravimétrie la quantité de matières volatiles condensée sur une surface froide en feuille d'aluminium. L'Annexe A donne les résultats d'un essai interlaboratoires qui montrent que si la Méthode B donne entière satisfaction, la Méthode A en revanche montre une variation importante du pourcentage de réflexion.
Les conditions d'essai permettent de mener les deux méthodes d'essai à la suite.

Usnje - Fizikalno in mehansko preskušanje - Ugotavljanje karakteristik meglenosti (ISO 17071:2006)

ISO 17071:2006 določa dve alternativni metodi za ugotavljanje karakteristik meglenosti usnja, ki se uporablja v prostorih za potnike v motornih vozilih, in sicer metodo A in metodo B. To sta dva različna preskusna postopka za merjenje hlapnih komponent in med rezultati, dobljenimi z metodo A, in rezultati, dobljenimi z metodo B, ni matematične korelacije.
Metoda A z odsevanjem določa lastnosti sipanja svetlobe (ali neprosojnost) in naravo filma ali nastajanje kapljic hlapnih komponent, ki se kondenzirajo na hladni stekleni površini. Metoda B gravimetrično meri količino hlapnih komponent, kondenziranih na hladni površini aluminijeve folije. Dodatek A podaja rezultate medlaboratorijskih poskusov, ki kažejo, da metoda B deluje dobro, pri metodi A pa prihaja do velikih variacij odstotka odsevanja.
Preskusni pogoji omogočajo, da se ta dva preskusa izvajata zaporedno.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 17071 was prepared by the Physical Test Commission of the International Union of Leather
Technologists and Chemists Societies (IUP Commission, IULTCS) in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of which is
held by UNI. It was published as EN 14288. It is based on DIN 75201 of Deutsches Institut für Normung and
on IUP 46 published in J. Soc. Leather Tech. Chem., 86 (7), p. 349, 2002, and declared an official method of
the IULTCS in May 2003.
IULTCS, originally formed in 1897, is a world-wide organization of professional leather societies to further the
advancement of leather science and technology. IULTCS has three Commissions, which are responsible for
establishing international methods for the sampling and testing of leather. ISO recognizes IULTCS as an
international standardizing body for the preparation of test methods for leather.

Leather — Physical and mechanical tests — Determination of
fogging characteristics
1 Scope
This International Standard specifies two alternative methods for determining the fogging characteristics of
leathers used in the passenger compartments of motor vehicles, namely Method A and Method B. 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. Annex A gives
the results of inter-laboratory trial which show that Method B performs well, whereas Method A showed a large
variation in the percentage reflection.
The test conditions allow the two tests to be carried out in succession.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 2418, Leather — Chemical, physical and mechanical and fastness tests — Sampling location
ISO 2419, Leather — Physical and mechanical tests — Sample preparation and conditioning
ISO 3696, Water for analytical laboratory use — Specification and test methods
3 Method A — Reflectometric method
3.1 Principle
A test piece is heated in a glass beaker, any volatile ingredients are condensed onto a cooled glass plate and
the reflectometric value of the glass plate with condensed fog is expressed as a percentage of the
reflectometric value of the same plate without fogging condensate. The measurement by light reflection
depends on the nature of the film/droplet formation and needs careful interpretation. An example is that a thick
but clear film can give a good test result when, in actual fact, it is a bad result in terms of volatiles. The test
should be stopped if a transparent oily film is formed on the glass. The reflection measurement result is only
valid when an even opaque film (like a fogged windscreen) formed by small droplets is present. (See Annex A.)
