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, 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, 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 ).

This document was prepared by ISO/TC 71, Concrete, reinforced concrete and pre-stressed concrete, Subcommittee SC 7, Maintenance and repair of concrete structures.

Introduction

ISO/TR 16475 outlines six basic properties and the required performance levels of water-leakage repair materials, and ISO/TS 16774‑1 through ISO/TS 16774‑6 provide test methods designed to evaluate the respective properties of these repair materials.

These test methods are intended to serve as references for nations that have not yet developed a test method on the six proposed required performance properties of water leakage repair materials. If other forms of test methods that are simpler, more accurate or more organized are available, such methods are recommended for use instead.

Many of the dependent variables outlined in the ISO 16774 series of reference test methods are subject to change in accordance with the environmental conditions (temperature; chemical substance and concentration; relative humidity; width of movement activity; water pressure or water flow velocity, etc.) outlined in the standards and testing parameters used in respective countries.

In ISO/TS 16774‑1, ISO/TS 16774‑5 and ISO/TS 16774‑6, for the purpose of objectively comparing the performance of injected repair materials, artificial cracks of same volume were used to control the usage of repair materials for each testing cycle and enable repetition of the same test methods under the same conditions.

1 Scope

This document specifies a laboratory test method for evaluating the thermal stress resistance of water-leakage crack repair materials through permeability testing.

The repair material injected into a test specimen with an artificial crack is thermally stressed under the applied temperature conditions outlined in different national testing parameters that reflect different environmental conditions. As such, the results are only intended to provide a comparative performance evaluation of the waterproofing repair materials between different products of the same type of repair material.

This document outlines general guidelines and procedures for the test method. Specific variables that control the quantifiable parameters of the testing are filled in using relevant national standardizations and/or testing parameters.
