Adhesives for leather and footwear materials - Determination of colour change of white or bright coloured leather surfaces by migration; German version EN 12705:2011
Klebstoffe für Leder- und Schuhwerkstoffe - Bestimmung der Farbänderung weißer oder hellfarbiger Lederoberflächen durch Migration; Deutsche Fassung EN 12705:2011
Overview
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, for example, adhesive coated linings for ironing, toe-puffs, reinforcing tapes or bonded materials. This standard supersedes DIN EN 12705:1999. In addition to editorial modifications, the normative references, in particular with regard to sampling, have been amended. The Committee responsible for this standard is NA 062-04-52 AA "Schuhe" ("Footwear") at DIN.
