Building and civil engineering sealants — Determination of resistance to prolonged exposure to water

This document specifies a method for the determination of the ability of sealants to resist differing degrees of exposure to water under conditions of service. The method assesses the effects of water immersion, for specified durations of time, on the ability of the sealant to fulfil its essential functions, principally to withstand joint movement.

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/

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 13638:1996), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— The title of the document has been modified.
— The requirements of apparatus, preparation of test specimens and failure criterion have been
modified in accordance with other revised ISO standards.
— The minimum times of repetition of the water immersion and cyclic movement procedures have
been defined.
Any feedback or questions on this document should be directed to the user’s national standards body. A

4 Principle
Test specimens are prepared in which the sealant to be tested adheres to two parallel contact surfaces.
After immersion of the test specimens in water under defined conditions, they are subjected to repeated
extension and compression movements in a suitable device, at an amplitude which is 50 % of that used
in the test to assess the respective movement accommodation factor. This procedure is repeated a
number of times, or until failure of one or more test spec
