Data sheets - Footwear tests materials and test adhesives

For research, development and quality certification purposes, some simply formulated 1- and 2-part “reference test adhesives” have been developed and, from the most important and most often applied, some materials have been selected as “reference test materials”. This document offers for each of these reference test adhesives and reference test materials some information and specify some properties. CEN/TC 193/WG 5 takes care for a continuous updating of these data sheets.

Datenblätter - Schuh-Testwerkstoffe und Schuh-Testklebstoffe

Für Forschungs-, Entwicklungs- und Qualitätszertifizierungszwecke wurden einige einfach formulierte 1  und 2-komponentige „Referenz-Testklebstoffe“ entwickelt, und von den wichtigsten und am häufigsten angewendeten Werkstoffen wurden einige als „Referenz-Testwerkstoffe“ ausgewählt. Dieses Dokument liefert Informationen über jeden dieser Referenz-Testklebstoffe und Referenz-Testwerkstoffe und legt einige Eigenschaften fest. CEN/TC 193/WG 5 sorgt für eine kontinuierliche Aktualisierung dieser Datenblätter.

European foreword
This document (CEN/TR 15990:2021) has been prepared by Technical Committee CEN/TC 193
“Adhesives”, the secretariat of which is held by UNE.
This document supersedes CEN/TR 15990:2010.
The main technical changes in comparison to the previous version are as follows:
— New information providers for test materials L1, L2, SBR and SBS in 3.1, 3.2, 3.3, 3.5 respectively;
— Update of company names.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

Introduction
For testing adhesive bonds some important European Standards have been developed by CEN/TC
193/Working Group 5 “Adhesives for Leather and Footwear” in close cooperation with European Shoe
Institutes and the “Association of European Adhesive and Sealant Manufacturers (FEICA)”:
— EN 1392:2006, Adhesives for leather and footwear materials — Solvent-based and dispersion
adhesives — Testing of bond strength under specified conditions
— EN 15062:2006, Adhesives for leather and footwear materials — Solvent-based and dispersion
adhesives — Testing ageing of bonds under specified conditions
— EN 15307:2014, Adhesives for leather and footwear materials — Sole-upper bonds — Minimum
strength requirement
These European Standards intend to serve:
— the manufactures of shoe materials for testing the bondability of their products;
— the adhesive manufactures to determine the bond properties of their adhesives;
— the shoe industry to test the suitability of the materials and/or adhesives before applying in their
production line and for quality control.
In the footwear industry a large number of different solvent or dispersion adhesives are applied for
sole-upper bonding offering a broad range of technical effects. The most important and most often
adhesives used are based on polyurethane and polychloroprene. For research, development and quality
certification purposes some simply formulated 1- and 2-part “reference test adhesives” have been
developed which can be considered as typical adhesives of these types. In footwear manufacture also a
great number of the different sole and upper materials are used. From the most important and most
often applied some materials have been selected as “reference test materials”.
The annexed data sheets offer for each of these reference test adhesives and reference test materials
some information and specify some properties. CEN/TC193 Working Group 5 takes care for a
continuous updating of these data sheets. For further information on a reference test adhesive or a
reference test material (e.g. on availability and supply) please contact the European Shoe Institute
