Adhesives - Guide to the selection of standard laboratory ageing conditions for testing bonded joints (ISO 9142:2003)
ISO 9142:2003 describes laboratory ageing conditions under which adhesive joints may be exposed to various environmental influences -- climatic or chemical -- for the purpose of assessing the effects of such influences on certain properties.
The ageing conditions are applicable to bonded assemblies and may be used to constitute a set of tests for the evaluation of an adhesive.
The results obtained using the procedures described in this International Standard are not necessarily applicable to the determination of the service life of a bonded assembly because there is no direct relation between the test results and the behaviour of a bonded assembly over a period of time under service conditions. However, for certain specific applications, experience with the procedures may enable a correlation to be established.
Klebstoffe - Auswahlrichtlinien für Labor-Alterungsbedingungen zur Prüfung von Klebverbindungen (ISO 9142:2003)
Diese Internationale Norm beschreibt Labor-Alterungsbedingungen, unter denen Klebverbindungen verschiedenartigen Umgebungseinflüssen - klimatisch oder chemisch - ausgesetzt werden können, um die Wirkungen dieser Einflüsse auf bestimmte Eigenschaften zu erfassen.
Diese Alterungsbedingungen sind auf Klebungen anwendbar und können dazu dienen, zur Bewertung eines Klebstoffes eine Prüfreihe festzulegen.
Die Ergebnisse, die nach dem in dieser Internationalen Norm beschriebenen Verfahren anfallen, berechtigen nicht ohne weiteres zu Aussagen zur Beständigkeit von Klebungen unter Praxisbedingungen, da keine unmittelbare Beziehung zwischen den Prüfergebnissen und dem Verhalten einer Klebung während einer bestimmten Zeit unter Praxisbedingungen gegeben ist. Bei speziellen Anwendungen lassen sich jedoch auf Grund von Erfahrungen mit diesem Verfahren Beziehungen herstellen.
ANMERKUNG Die Alterungsbedingungen sollten in Beziehung zur speziellen Anwendung des Klebstoffes stehen.
Adhésifs - Guide pour la sélection de conditions normales d'essai de vieillissement en laboratoire des assemblages collés (ISO 9142:2003)
L'ISO 9142:2003 décrit les conditions d'exposition des assemblages collés à différentes contraintes d'environnement. Celles-ci peuvent être climatiques ou chimiques. Elle permet d'en déterminer l'influence sur certaines caractéristiques données.
Les conditions de vieillissement sont applicables aux assemblages collés et peuvent servir à constituer un ensemble d'essais d'évaluation d'un adhésif.
Les résultats d'essai obtenus à partir des méthodes décrites dans la présente Norme internationale ne sont pas nécessairement applicables à l'évaluation du comportement d'un assemblage dans le temps, car il n'est pas possible d'établir une relation directe entre les résultats d'essai et le comportement dans le temps et dans les conditions de service d'un assemblage collé. Cependant, pour certaines applications, l'expérience peut permettre d'établir une certaine corrélation.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 9142 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.
This second edition cancels and replaces the first edition (ISO 9142:1990), of which it constitutes a minor
revision.

INTERNATIONAL STANDARD ISO 9142:2003(E)
Adhesives — Guide to the selection of standard laboratory
ageing conditions for testing bonded joints
1 Scope
This International Standard describes laboratory ageing conditions under which adhesive joints may be
exposed to various environmental influences — climatic or chemical — for the purpose of assessing the
effects of such influences on certain properties.
The ageing conditions are applicable to bonded assemblies and may be used to constitute a set of tests for
the evaluation of an adhesive.
The results obtained using the procedures described in this International Standard are not necessarily
applicable to the determination of the service life of a bonded assembly because there is no direct relation
between the test results and the behaviour of a bonded assembly over a period of time under service
conditions. However, for certain specific applications, experience with the procedures may enable a
correlation to be established.
NOTE The ageing conditions should preferably be related to the specific application of the adhesive.

4.5 Controlled-pressure chamber, capable of operating at a pressure of 0,6 MPa and at an underpressure
of 0,092 MPa.
5 Specimens
5.1 Number and type
The number of test specimens, and the type used, will depend on the properties to be measured and the
required ageing conditions. The test specimens shall be prepared in accordance with the requirements of the
appropriate ISO standard test method. Prepare a sufficient number of specimens to provide homogeneous
sets of samples for testing and to provide control samples. The following International Standards, which do not
constitute an exhaustive list, are applicable: ISO 4587, ISO 4588, ISO 6238.
5.2 Conditioning
Specimens shall be conditioned in the conditioning chamber (4.1) for a minimum duration of 24 h before being
subjected to ageing. The conditioning shall be carried out after the adhesive has been cured in accordance
with the materials specification or the methods specified by the manufacturer of the adhesive.
6 Procedure
6.1 Tests before ageing
Determine the properties required for the sample under test by the appropriate test method, using specimens
conditioned in accordance with 5.2.

6.2 Ageing
Expose conditioned specimens to the environmental conditions as defined in Annex A to Annex F, as required.
6.3 Tests after ageing
Determine the properties after ageing in accordance with the procedure(s) of the appropriate standard(s).
Unless there are indications to the contrary in the Annexes, condition test specimens in the conditioning
chamber (4.1)
for (3 ± 1) h in the case of specimens exposed at a relative humidity higher than 50 %,
for at least 24 h for all other specimens,
before determining the properties.
In addition to the test results, all changes visible during the ageing and testing periods, including mode of
failure, shall be noted.
6.4 Controls
For control purposes, a representative group of specimens shall be kept in the conditioning chamber (4.1) for
the period of time covered by the ageing conditions selected.
7 Expression of results
For properties that can be measured, the results obtained are expressed as either
absolute values or
a relative variation with respect to the initial value.
For properties that cannot be measured, the nature of the effects observed shall be noted, e.g. rupture
between the substrate and adhesive, failure of cohesion of the adhesive joint due to partial or total corrosion
of the substrate beneath the adhesive, etc.
NOTE It may be worth verifying that the variation in a measured property is caused only by the ageing process from
the following three values:
A the value of the property measured before accelerated ageing;
B the value of the same property measured on the control specimen which has undergone only intrinsic ageing at
(23 ± 2) °C and (50 ± 5) % R.H. (see 6.4);
C the value of the property measured after ageing.
This can be done by calculating the following ratios:
a) [(A – B)/A] × 100 (this ratio represents the intrinsic ageing during the period concerned);
b) [(A – C)/A] × 100 (this ratio represents the overall ageing due to intrinsic ageing and the accelerated ageing under the
conditions specified in this International Standard);
c) [(B – C)/A] × 100 (this ratio represents the degree of ageing due to ageing under the conditions specified in this
International Standard).
