Adhesives for leather and footwear materials - Determination of colour change of white or bright coloured leather surfaces by migration

This European Standard specifies a method to determine the colour change of white or bright coloured leather surfaces caused by adhesives and/or their basic constituents migrating from the reverse sides to their upper surfaces.
This change of colour may be caused either by the adhesive directly or by adhesive coatings on materials used in footwear manufacture, e.g. adhesive coated linings for ironing, toe-puffs, reinforcing tapes or bonded materials.

Klebstoffe für Leder und Schuhwerkstoffe - Bestimmung der Farbänderung weißer oder hellfarbiger Lederoberflächen durch Migration

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Farbänderung weißer oder hellfarbiger Lederoberflächen fest, die von Klebstoffen und/oder ihren Basiskomponenten durch Migration von der Rück-seite weißer oder hellfarbiger Leder auf deren Oberseite hervorgerufen wird.
Diese Farbänderung kann entweder unmittelbar durch den Klebstoff selbst oder durch Klebstoffschichten auf Werkstoffen verursacht werden, die bei der Schuhherstellung verwendet werden, z. B. klebstoffbeschichtete, einbügelbare Futterstoffe, Schuhkappen, Verstärkungsbänder oder bereits geklebte Materialien.

Adhésifs pour le cuir et les matériaux de chaussures - Détermination du changement de couleur par migration des surfaces de cuir blanc ou de couleurs claires

La présente Norme européenne spécifie une méthode de détermination du changement de couleur des surfaces de cuir blanc ou de couleurs claires lié à la migration des adhésifs et/ou de leurs constituants de base, des revers vers les faces supérieures.
Ce changement de couleur peut être causé, soit directement par l’adhésif, soit par les revêtements adhésifs présents sur les matériaux utilisés dans la fabrication des chaussures, par exemple les doublures enduites d’adhésifs, les raidisseurs de bout, les rubans de renfort ou les matériaux enduits.

Lepila za usnje in obutvene materiale - Ugotavljanje spremembe barve belih ali svetlo obarvanih usnjenih površin zaradi migracije

Ta evropski standard določa metodo določevanja spremembe barve belih ali svetlo obarvanih usnjenih površin, ki jo povzročajo lepila in/ali njihove osnovne sestavine, ki migrirajo od zadnje strani do zgornjih površin.
To spremembo barve na materialih, ki se uporabljajo v proizvodnji obutve, npr. lepilni premazi za glajenje obutve, prstne blazinice, trakovi za ojačanje ali vezani materiali, lahko povzroči lepilo samo ali pa njegova prevleka.
