Leather - Physical and mechanical tests - Determination of heat resistance of patent leather
This European Standard specifies two methods for determining the heat resistance of patent leather. Method A makes use of a modified lastometer whilst Method B uses the 'Zwik' apparatus. Both methods are applicable to patent leathers for all end uses.
Leder - Physikalische und mechanische Prüfungen - Wärmebeständigkeit von Lackleder
Diese Europäische Norm legt zwei Verfahren zur Bestimmung der Wärmebeständigkeit von Lackleder fest. Verfahren A benutzt ein modifiziertes Lastometer, während beim Verfahren B das "Zwik" Gerät angewendet wird. Beide Verfahren sind für Lackleder für jede Endanwendung geeignet.
Cuir - Essais physiques et mécaniques - Détermination de la résistance à la chaleur des cuirs vernis
La présente Norme européenne spécifie deux méthodes visant à déterminer la résistance à la chaleur du cuir vernis. La méthode A met en �uvre un dispositif de charge modifié et la méthode B utilise l'appareillage " Zwik ". Ces deux méthodes sont applicables aux cuirs vernis indépendamment de leurs utilisations finales.
