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 document 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 ).

Introduction

This document defines and specifies site application of products and systems and quality control of repairs. The execution of maintenance and repair of concrete structures is an important and integral part of the complex process of repair, and this document specifies how it is carried out. This document incorporates rules for the use of maintenance and repair materials and systems. Maintenance and repair methods applying traditional concrete construction work are listed in this document. Maintenance and repair methods applying electrochemical methods, e.g. cathodic protection, re-alkalisation of carbonated concrete, and chloride extraction, are listed in this document.

1 Scope

This document provides requirements for substrate condition before and during application, including structural stability, storage of materials, the preparation, and application of products and systems for repair of concrete structures, including quality control and qualifications of personnel, maintenance, health and safety, and the environment.
