Adhesives - Determination of dynamic resistance to cleavage of high-strength adhesive bonds under impact wedge conditions - Wedge impact method (ISO 11343:2019)

This document specifies a dynamic impact wedge method for the determination of the cleavage resistance under impact loading of high-strength adhesive bonds between two adherends, when tested under specified conditions of preparation and testing. This test procedure does not provide design information.
The method allows a choice of sheet metal or fibre reinforced plastic substrates corresponding to those materials frequently used in industry, such as for automotive applications.

Klebstoffe - Bestimmung des dynamischen Keil-Schlag-Widerstandes von hochfesten Klebungen unter Keilschlagbelastung - Keil-Schlag-Verfahren (ISO 11343:2019)

Dieses Dokument legt ein dynamisches Keil-Schlag-Verfahren für die Bestimmung des Keil-Schlag-Widerstandes unter Schlagbelastung hochfester Klebungen zwischen zwei Substraten, die unter festgelegten Bedingungen hergestellt und geprüft werden, fest. Dieses Verfahren liefert keine Informationen für die Konstruktion.
Dieses Verfahren gestattet, Metallbleche oder faserverstärkte Kunststofffügewerkstoffe, die solchen entsprechen, die in der Industrie häufig, wie z. B. für den Automobilbau, eingesetzt werden, zu wählen.

Adhésifs - Détermination de la résistance dynamique au clivage de joints collés à haute résistance soumis aux conditions d'impact - Méthode d'impact au coin (ISO 11343:2019)

Le présent document spécifie une méthode d'essai d'impact au coin pour la détermination de la résistance au clivage de joints collés à haute résistance soumis à une charge dynamique entre deux supports collés, dans des conditions spécifiées de préparation et d'essai. Ce mode opératoire d'essai ne fournit pas d'informations relatives à la conception.
Cette méthode permet d'opter pour des substrats métalliques en tôle ou des substrats en plastique renforcé de fibres, qui correspondent aux matériaux fréquemment utilisés dans l'industrie, notamment l'industrie automobile.

Lepila - Ugotavljanje dinamične odpornosti proti cepitvi lepljenih spojev z veliko trdnostjo pod udarnimi klinom - Metoda z udarnim klinom (ISO 11343:2019)

Ta dokument določa metodo z udarnim klinom za ugotavljanje dinamične odpornosti proti cepitvi lepljenih spojev z veliko trdnostjo med lepljencema proti udarnim obremenitvam pri preskušanju pod določenimi pogoji za pripravo in preskušanje. Ta preskusni postopek ne podaja informacij o zasnovi.
Metoda omogoča izbiro pločevine ali z vlakni ojačanih plošč iz polimernih materialov, ki ustrezajo pogosto uporabljenim materialom v industriji, na primer za avtomobilsko uporabo.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

.org/iso/foreword .html.

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11,

Products.

This third edition cancels and replaces the second edition (ISO 11343:2003), which has been technically

revised. The main changes compared to the previous edition are as follows:
a) added new terms and definitions;
b) explicitly included usage of different test machines in apparatus;
c) added Note regarding signal filtering;
d) added representative points in force-time figures;
e) minor editorial changes.

Any feedback or questions on this document should be directed to the user’s national standards body. A

3.1
dynamic resistance to cleavage

force per unit width necessary to bring an adhesive joint to the point of failure by means of a stress

applied by a wedge moving between the two substrates of the joint, and thus separating the adherends

in a cleaving mode

Note 1 to entry: The dynamic resistance to cleavage is expressed in kilonewtons per metre.

3.2
cracking force
maximum force after which the force falls to a plateau
Note 1 to entry: The cracking force is expressed in newtons.

Note 2 to entry: Typically, it is also the highest force measured. It characterizes the beginning of cracking.
