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).

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.

This document was prepared by Technical Committee ISO/TC 59, Buildings and civil engineering works, Subcommittee SC 8, Sealants.

This third edition cancels and replaces the second edition ( ISO 13640:2018 ), which has been technically revised.

The main changes are as follows:

the title has been revised from Buildings and civil engineering works — Sealants —Specifications for test substrates;
normative references have been updated;
in Clause 4, the dimensions of the interface substrate or sealant have been added as a reminder;
in 4.1.1, 4.2.1 and 4.3.1, regarding the substrate dimensions: “or other dimensions as agreed between the concerned parties” has been added;
4.2.2 has been added to provide specifications for glass substrates, in the same way as for other substrates;
4.3.2 has been renamed to “Substrate specifications” for anodized aluminium substrates.

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.

1 Scope

This document specifies the procedures for producing substrates of mortar, glass and anodized aluminium used for testing sealants.

This document defines the composition and the method of preparation of the test substrates to ensure the reproducibility of the tests conducted on sealants.

The substrates defined in this document are indicators of the sealant's performance and not substrates which reproduce the characteristics of the construction materials.
