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 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 59, Buildings and civil engineering works,
Subcommittee SC 8, Sealants, in collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/SS B02, Structures, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 6927:2012), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— modified the title;
— added important terminology for the property of the sealant to reflect the progress of the sealant
technology.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/ members .html.

Building and civil engineering sealants — Vocabulary
1 Scope
This document defines technical terms for self-levelling and gun-grade (gunnable) sealants for above-
ground exposed structures.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content

3.1 Sealant classification
3.1.1
seal
install the appropriate products in the joint (3.2.15) between components in order to prevent the
penetration of water, moisture and/or air between the elements, components and assemblies made of
the same or dissimilar materials
3.1.2
sealant
text material applied in an unformed state which, once cured (3.4.7) or dried, has the adhesive and
cohesive properties to seal (3.1.1) a joint (3.2.15)
3.1.3
elastic sealant
sealant (3.1.2) in which the stresses (3.5.8) induced as a result of joint (3.2.15) movement are nearly
proportional to the strain (3.5.7)
Note 1 to entry: The elastic behaviour of the sealant is evaluated by the elastic recovery (3.5.10) measurement
(see ISO 7389).
3.1.4
plastic sealant
sealant (3.1.2) in which the stresses (3.5.8) induced as a result of joint (3.2.15) movement are nearly
proportional to the rate of joint movement and are rapidly relieved when joint movement ceases
Note 1 to entry: The plastic behaviour of the sealant is evaluated by the elastic recovery (3.5.10) measurement
(see ISO 7389).
3.1.5
one component sealant
sealant (3.1.2) ready for use not requiring mixing

mixing together
