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.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee Technical Committee ISO/TC 46, Information and
documentation, Subcommittee SC 10, Requirements for document storage and conditions for preservation, in
collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 172,
Pulp, paper and board, in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 9706:1994), which has been technically
revised.
The main changes are as follows:
— the Introduction has been modified and Annex D has been added to emphasize the relationship and
differences between existing standards regarding the requirements of paper for different applications:
permanent and durable paper for documents which are intended to be used frequently and kept
permanently, and for stable paper used for general graphic applications;
— the normative references have been updated;
— the term "document" has been replaced by an existing definition in the terminology database of ISO.
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.

Introduction
Librarians and archivists have found that paper documents made as recently as the second half of the
th
20 century show serious deterioration under typical library and archive storage conditions. Contrary to
this observation, the past 1 500 years of paper use show that papers consisting mostly of cellulose have
considerable permanence and durability.
Research indicates that the deterioration is due to the presence of cellulose-degrading compounds in the
paper furnish and materials incorporated in the paper during manufacture, e.g. acidic materials such as
rosin-alum size.
The intention of this document is to define a permanent paper that is most suitable for indefinite storage,
e.g. in archives, libraries, and museums. Such paper is to be used
