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 on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

Subcommittee SC 8, Sealants.

INTERNATIONAL STANDARD ISO 11618:2015(E)
Buildings and Civil Engineering Works — Sealants —
Classification and requirements for pedestrian walkway
sealants
1  Scope
This International Standard applies to sealants used for pedestrian walkways, public areas, movement
joints between concrete slabs, areas with pedestrian load, areas which are used with trolleys, parking
garages, walkable floors, balconies, terraces, and warehouses.
This International Standard specifies the types and classes of elastic sealants used in building
construction pedestrian walkways according to their performance characteristics. Sealant may be
either non-sag or self-leveling as declared by the manufacturer. Areas of application are floor joints
which have been designed.
Chemical containment, cold applied joint sealants for concrete pavements to be used in roads, airfields,
and sewage treatment plants are excluded.
Local regulations may be required in addition to this International Standard based on local laws and
codes.

4  Classification
4.1 Classes
Sealants are classified according to their ability to fulfill sealing functions in joints with movement
parameters as given in Table 1.
a
Table 1 — Sealant classes
Class Test amplitude %
25 ±25
20 ±20
12,5 ±12,5
a
For the correct interpretation and application of movement capability to the design of joints, relevant national
standards and advisory documents should be considered.
4.2  Subclasses
4.2.1 Sealants of class 25 and 20 are additionally sub-classified according to their secant tensile modulus.
Low modulus: code LM.
High modulus: code HM.
If the measured secant tensile modulus value at 100% strain exceeds the values specified below for
either or both temperatures, the sealant shall be classified as high modulus. Specified values (see
Table 2 and Table 3) are as follows:
2 °
0,4 N/mm at + 23 C (1)
2 °
0,6 N/mm at – 20C (2)
The secant modulus shall be the mean value of the three measured values. Round the mean value to one
decimal place.
