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 document 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.
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, 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 fourth edition cancels and replaces the third edition (ISO 10364:2015), which has been technically
revised.
The main changes are as follows:
— subclause 6.6, Method 5: Determination by control of “snap time”, has been added.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Structural adhesives — Determination of the pot life (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 of an adhesive.
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 are 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.
