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 ).

Introduction

The ISO 24283 series specifies the qualification criteria for geotechnical investigation and testing and has three parts:

• Part 1: Qualified technician and qualified operator
• Part 2: Responsible expert
• Part 3: Qualified enterprise

The fulfilment of the technical criteria by the enterprise or the individual can be proven by:

• a) a declaration of conformity by a contractor (first party control);
• b) a declaration of conformity by a client (second party control);
• c) a declaration of conformity by a conformity assessment body (third party control).

1 Scope

This document specifies the qualification criteria for enterprises performing sampling, testing, measuring, monitoring and installation of equipment (e.g. piezometers, borehole heat exchangers, inclinometers and extensometers) in the framework of geotechnical investigation.
