Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.

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 document should be noted (see www.iso.org/directives).

Introduction

Anyone who processes confidential, personal and/or sensitive data for themselves or on behalf of others must ensure that data carriers containing such information are safely destroyed in a way that ensures privacy.

In this context, safely destroyed means that data carriers containing sensitive data must be destroyed in such a way that reproduction of the information on them is either impossible or is only possible with considerable expenditure (in terms of personnel, resources and time).

NOTE This standard takes into account that data carriers have different physical characteristics and contain information with various levels of sensitivity.
