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.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 46, Information and documentation,
Subcommittee SC 10, Requirements for document storage and conditions for preservation, Working group WG7,
Requirements for materials related to preservation.
This second edition cancels and replaces the first edition (ISO 9706:1994).
The main changes are as follows:
— Modification of the Introduction and addition of an Annex to emphasize the relationship and differences
between existing standards on permanence, durability and stability of papers.
— Normative references updating.
— Modification of the term Document to use 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

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 ISO 9706 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 for books as well as for files, documents and other
records that are to be stored permanently for legal, cultural policy or other reasons. For this purpose, this
document provides a method for specifying paper which, according to the present state of knowledge, has a
high degree of permanence. Paper fulfilling the requirement of this document shows no or only slight changes
in optical and mechanical properties which have an influence on readability of recording (printing, writing
or copying) and handling when stored for a long period in a protected environment. This purpose requires
papers eligible for permanent use to be free of oxidizable matter that causes undesirable discolouration
e.g. lignin or recycled material of uncertain composition, and/or substances that have a negative impact on
mechanical strength, for example any type of acid sizing or other acid-producing substances.
This document is based on a small number of quantitative tests for which limiting values have been specified.
Paper classified in accordance with this document shall show measurement results within the specified
limits for all prescribed tests.
The limits are chosen so that paper conforming to the specifications of this document can be produced in large
quantities at reasonable prices. This permits printing firms, publishing companies, public administration,
and others to use this paper for all types of written and printed matter, files and records, or publications
which for any reason are to be preserved indefinitely in libraries, archives or any other entities concerned in
this matter.
There are two standards, apart from ISO 9706, regarding either permanence, durability or stability of
papers:
— ISO 11108, Information and documentation - Archival paper - Requirements for permanence and durability
(permanent and durable paper), which describes archival paper with the same permanence requirements
as for ISO 9706 and with high durability (able to withstand the effects of wear and tear during use).
— ISO 20494 - Paper - Requirements for stability for general graphic applications (stable paper), which describes
paper for general graphic applications, not intended for permanent storage, including newspapers,
magazines, catalogues, books, office printouts and copies where changes in optical properties over time
can be tolerated.
The present ISO 9706 and ISO 11108 differ from ISO 20494; they are not comparable either in approach or in
method. In ISO 20494, the decrease in mechanical-physical strength that a paper suffers when subjected to
moist heat treatment for up to 12 days is the basis for defining service life despite any optical changes.
Conversely, ISO 9706 and ISO 11108 are based on the fact that acid-catalyzed hydrolysis
