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.

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 the following

This document was prepared by Technical Committee ISO/TC 59, Buildings and civil engineering works,
Subcommittee SC 8, Sealants.
This second edition cancels and replaces the first edition (ISO 8394-2:2010), which has been technically
revised.
The main change compared to the previous edition is as follows:

Part 2:
Using standardized apparatus
1 Scope
This document specifies a method for determining the extrudability of sealants independently of the
package in which they are supplied.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For

4 Principle
The tested sealant is filled in a standardized apparatus.
The sealant is extruded under defined conditions. The mass of the extruded sealant is determined.
This document specifies reference test conditions, such as temperature, pressure, extrusion time and
geometry of cylinder. Deviation from these conditions is possible. Deviation modifies the final result;
therefore, any deviation shall be descr
