Adhesives for leather and footwear materials - Determination of optimum activation temperatures and maximum activation life of solvent-based and dispersion adhesives
This European Standard describes the determination of optimum heat activation temperature and maximum activation life of solvent-based or dispersion adhesives coated onto adherends, primarily based on the requirements for sole attaching adhesives. Optimum heat activation temperature and maximum heat activation life depend mainly on the type, composition and colour of the adhesive as well as the footwear material used.
Klebstoffe für Leder und Schuhwerkstoffe - Bestimmung der optimalen Aktiviertemperatur und der maximalen Dauer der Aktivierbarkeit von Lösemittel- und Dispersionsklebstoffen
1 Anwendungsbereich
Diese Europäische Norm legt die Bestimmung der optimalen Wärmeaktiviertemperaturen und der maximalen
Dauer der Aktivierbarkeit von Lösemittel- und Dispersionsklebstoffen, die auf Fügeteile aufgetragen werden
und primär auf die Anforderungen an Klebstoffe für Schuhsohlen abgestimmt sind, fest. Die optimalen
Wärmeaktiviertemperaturen und die maximale Dauer der Aktivierbarkeit hängen hauptsächlich von Art,
Zusammensetzung und Farbe des Klebstoffes sowie vom verwendeten Schuhwerkstoff ab.
Adhésifs pour cuir et matériaux pour articles chaussants - Détermination de la température optimale d'activation et de la durée maximale d'activation des adhésifs a base de solvant et en dispersion
1 Domaine d'application
La présente norme européenne spécifie la détermination de la température optimale d'activation par la chaleur et la durée maximale d'activation d'adhésifs a base de solvant ou en dispersion appliqués sur des supports, principalement fondée sur les exigences relatives aux adhésifs de fixation de la semelle. La température optimale d'activation par la chaleur et la durée maximale d'activation par la chaleur dépendent essentiellement du type, de la composition et de la chaleur de l'adhésif ainsi que du matériau pour articles chaussants utilisé.

Thecoats applied are dried for a specified period of time under specified conditions.For determination of the optimum activation temperatures coats on sole material strips are heat activated to varioussurface temperatures at intervals of 10 C from 50 C to 90 C, unless otherwise specified, and immediatelyassembled with dried but not activated coats on strips cut from upper material. The test pieces produced are storedfor a specified time under specified conditions before their strength is determined in a peel test in accordance withEN 1392.SIST EN 12961:2002
