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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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
in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC
193, Adhesives, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This fifth edition cancels and replaces the fourth edition (ISO 10364:2024), which has been technically
revised.
The main changes are as follows:
— The structure of the standard has been changed making it more user friendly. Each of the methods is
now described in a separate clause containing the list of materials and equipment, a description of the
procedure and the specific requirements for the content of the test report;
— The somewhat misleading information on the relevance of the respective methods of some methods has
been adjusted;
— The option of mixing the adhesive components using a dual asymmetric centrifuge has been added;
— Clause 3.1 pot life: definition adjusted;
— Clause 3.2 working life: definition adjusted;
— Clause 11: Method 6: Pot life - Determination from the change in wetting properties has been added;
— Clause 12: Method 7: Pot life - Determination – from the change in tensile lap shear strength has been
added;
— Clause 13: Method 8: Working life - Determination – from the change in tensile lap shear strength has
been added.

Structural adhesives — Determination of the pot life and
working life of multi-component adhesives
SAFETY STATEMENT — Persons using this document should be familiar with normal laboratory
practice, if applicable. This document does not purport to address all of the safety concerns, if any,
associated with its use. It is the responsibility of the user to establish appropriate safety and health
practices and to determine any regulatory requirements prior to use.
1 Scope
This document specifies methods for determining the pot life of multi-part adhesives, in order to be able
to determine whether the pot life conforms to the minimum specified working life required for a specific
bonding process or to determine the reactivity of a multi-component adhesive as part of an incoming or
outgoing goods inspection.
The different methods described in this document to measure the property do not necessarily provide
identical results.
The test methods described are suitable for assessing all multi–part adhesives, and especially epoxy based
and polyurethane based adhesives, but they may not suitable for some acrylic-based adhesives.
NOTE 1 Some of the methods described in this document can also be suitable for determination of working life of
one-part adhesives that react to humidity (e.g. PUR prepolymers).
NOTE 2 This document can also be used for assessing non-structural adhesives.

3.1
pot life
maximum time period, starting with the first contact of the components of a multi-component adhesive,
within which the rheological properties of the adhesive allow it to be dispensed to the adherend and
sufficiently wet both this and the adherends applied during joining; the steps to be carried out within the
pot life are: dosing and mixing of the components, dispensing of the mixed adhesive to the adherend, joining
and clamping the adherends
Note 1 to entry: The pot life varies with volume (more precisely with the surface to volume ratio of the tested adhesive
sample), the temperature of the mixed adhesive and the ambient temperature.
3.2
working life
pot life plus the time interval within which the adherends can still be repositioned slightly by moving them
parallel to each other after joining without adversely affecting the bond
Note 1 to entry: The pot life varies with volume (more precisely with the surface to volume ratio of the tested adhesive
sample), the temperature of the mixed adhesive and the ambient temperature.
3.3
open time
maximum permissible time interval between the start of the application of the adhesive to the adherends
and the completion of the joining process
[SOURCE: EN 923: proposed revised wording]
4 Significance and use
The pot life as well as the working life of a multi-component adhesive are important adhesive properties with
regard to its processing. Even if the information about the pot life in the technical data sheets was originally
intended to give the adhesive user an indication of how long an adhesive can be processed after mixing the
individual components, methods have now also been established that allow to check the adhesive’s reactivity
as part of quality assurance, whether in outgoing or incoming goods inspection, but do not necessarily allow
conclusions to be drawn about s
