Adhesives - Determination of tensile strength of butt joints (ISO 6922:1987 modified)

This European Standard specifies a method for determining the bond strength of a butt joint when subjected
to tensile force. The method can be applied to all types of adhesives. Although primarily intended for use
under ambient conditions, the basic method can also be applied to testing under a wide range of temperature
and other environmental conditions. The method requires rigid adherends that can be produced to the
required dimensional tolerances and that will withstand the forces applied to them during the test.

Klebstoffe - Bestimmung der Zugfestigkeit von Stumpfklebungen (ISO 6922:1987 modifiziert)

Diese Europäische Norm legt ein Verfahren zur Bestimmung der Festigkeit einer Stumpfklebung fest, wenn
diese mit einer Zugkraft beansprucht wird. Das Verfahren ist auf alle Arten von Klebstoffen anwendbar.
Obwohl es in erster Linie zur Anwendung unter normalen Umgebungsbedingungen vorgesehen ist, kann das
Grundverfahren auch für eine Prüfung in einem weiten Temperaturbereich und unter anderen Umgebungsbedingungen
angewendet werden. Das Prüfverfahren erfordert starre Fügeteile, die mit den geforderten
Maßtoleranzen herstellbar sind und der Zugbeanspruchung widerstehen, die während der Prüfung auf sie
einwirkt.

Adhésifs - Détermination de la résistance en traction des joints bout à bout (ISO 6922:1987 modifiée)

La présente Norme européenne spécifie une méthode de détermination de la résistance à la rupture d’un joint
extrémité à extrémité soumis à une force de traction. La méthode peut être appliquée à tout type d’adhésif.
Bien que primitivement destinée à être utilisée dans des conditions ambiantes, la méthode de base peut aussi
être appliquée pour effectuer des essais dans une large gamme de températures et d’autres conditions
d’environnement. La méthode nécessite des supports rigides qui peuvent être usinés aux tolérances
dimensionnelles requises et qui seront à même de supporter les forces appliquées pendant toute la durée de
l’essai.

Overview

EN 15870:2009 (CEN) defines a standardized method for determining the tensile bond strength of butt joints. Based on ISO 6922:1987 (modified), the method is applicable to all adhesive types and is primarily intended for ambient-condition testing but can be applied across a wide range of temperatures and environmental conditions. The standard requires rigid adherends that meet dimensional tolerances and can withstand test forces.

Key Topics

  • Principle: A butt joint formed from two bar or rod adherends, bonded on faces normal to the length, is loaded in tension along its long axis until rupture. The reported result is the force observed at rupture.
  • Apparatus: A Class 1 testing machine complying with EN ISO 7500-1 is required. The machine must measure force accurately (recorded force within 1% of true force) and allow steady, controlled increase of load. Self-aligning grips and a simple jig for alignment during bonding are specified.
  • Test specimens: Adherends should be rigid and, for comparative testing, identical materials. Typical cross-sections permitted include circular or square (10, 15, 25 or 50 mm) with tolerances of ±0.1 mm; length rules are defined in the standard. Surfaces must be plane and normal to the long axis and prepared per adhesive manufacturer or EN 13887.
  • Bonding and conditioning: Use manufacturer-recommended bonding procedures or those that produce an optimum bond. Condition specimens under standard atmosphere (recommended 23 ± 2 °C and 50 ± 5 % RH per EN ISO 291) unless otherwise specified.
  • Procedure and reporting: Apply tensile loading at a constant jaw separation rate approximating 10 mm/min so that rupture occurs in (60 ± 20) s. Record the maximum force at rupture and the failure mode (per EN ISO 10365). Report the mean of five valid results, specimen details, bonding conditions, adhesive identification, adhesive layer thickness, and failure types.

Applications

  • Quality control and batch verification of adhesives
  • Comparative R&D testing of adhesive formulations
  • Material qualification for bonded assemblies in design and production
  • Environmental conditioning and performance assessment across temperatures and humidity

Related Standards

  • EN ISO 7500-1 - Verification of static uniaxial testing machines
  • EN ISO 291 - Standard atmospheres for conditioning and testing
  • EN ISO 10365 - Designation of main failure patterns
  • EN 13887 - Surface preparation guidelines for metals and plastics
  • ISO 5893, ISO 3534, EN ISO 472 (referenced for related test and statistical guidance)

This standard provides a practical, reproducible method for measuring adhesive bond strength of butt joints, facilitating consistent reporting for QC, certification and laboratory comparison.
