IS0 9706:1994(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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. IS0 collaborates closely with the International Electrotechnical Commission (I EC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard IS0 9706 was prepared by Technical Committee ISOnC 46, Information and documentation, Subcommittee SC 10, Physi- cal keeping of documents. IS0 9706 was developed on the basis of the standard ANSI 239.48:1984, American National Standard for Information Sciences - Permanence of Paper for Printed Library Materials. That standard was revised in 1992, and the technical requirements of this International Standard are in conformity with the standard ANSI/NISO 239.48:1992, American National Standard for Permanence of Paper for Publications and Documents in Libraries and Archives. The limiting values of two of the four required characteristics, viz. tear resistance and resistance to oxidation, differ slightly. A symbol of compliance in the form of the mathematical symbol denoting infinity set inside a circle was developed by NISO, the US National Information Stan- dards Organization and introduced in ANSI Z39.48:1984. The NISO symbol is now part of ANSI/NISO 239.48:1992. The symbol is used in this Inter- national Standard with the permission of NISO.

Q IS0 IS0 9706: 1994(E) Introduction Librarians and archivists have found that paper documents made as re- cently as 50 years ago are beginning to show serious deterioration under typical library and archive storage conditions. The history of the past 1 500 years shows that fibres of pure cellulose have considerable perma- nence. Modern research indicates that the deterioration is due to the presence of cellulose-degrading compounds in the paper furnish and ma- terials incorporated in the paper during manufacture, e.g. acidic materials such as rosin-alum size. The purpose of this International Standard is to provide a means of speci- fying and identifying paper that, according to the present state of know- ledge, has a high degree of permanence and is likely to undergo little or no change in properties that influence readability and handling when stored in a protected environment for long periods of time. Standardization of document storage requirements is in progress within lSO/TC 46/SC lO/WG 3 (at present IS0 WD 11799, documents IS0 46/10/3 N 1 to 5). This International Standard is based on a limited number of quantitative tests. For each test, limiting values have been laid down. A paper, to be classified in accordance with this International Standard as being suitable for long life documents, records and publications must show test values within the limits given for all the tests prescribed. The limiting values have been selected so that bulk quantities of paper classified by this International Standard can be produced at reasonable cost. This will allow book printers, publishers, offices, and others to use the paper for all types of documents, records or publications which for some reason are likely to be stored in libraries or archives for a prolonged period. Papers for sale that comply with the requirements in this International Standard and documents produced on such papers may be identified by a symbol and a statement of compliance. This symbol and statement is described in annex B. The rationale for exclusion of in annex C. some commonly used paper tests is given This International Standard can be used as a specification as it stands. It can also be incorporated as an element in other specifications, used in trade, or in other national or International Standards for more specialized purposes. . . . III SIST EN ISO 9706:2000

INTERNATIONAL STANDARD 0 IS0 IS0 9706:1994(E) Information and documentation - Paper for documents - Requirements for permanence 1 Scope This International Standard specifies the requirements for permanent paper intended for documents. It is applicable to unprinted papers. It is not applicable to boards. NOTE 1 The terms paper and board are defined in IS0 4046. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most re- cent editions of the standards indicated below. Members of IEC and IS0 maintain registers of cur- rently valid International Standards. IS0 186:1985, Paper and board - Sampling to deter- mine average quality. IS0 187: 1990, Paper, board and pulps - Standard atmosphere for conditioning and testing and pro- cedure for monitoring the atmosphere and condition- ing of samples. IS0 302:1981, Pulps - Determination of Kappa number. IS0 536: 1976, Paper and board - Determination of grammage. YSO 1974:1990, Paper - Determination of tearing re- sistance (E/mendorf method).

IS0 10716: -l) Paper and board - Determination of , alkali reserve. 3 Definitions For the purposes of this International Standard, the following definitions apply. 3.1 document: Paper upon which information is re- corded (see also IS0 5127-I). 3.2 permanence: The ability to remain chemically and physically stable over long periods of time. 3.3 permanent paper: Paper which during long term storage in libraries, archives and other protected environments will undergo little or no change in properties that affect use. NOTE 2 Examples of use of a document include, but are not limited to, the ability of the document to be handled, read, examined, or copied for the purposes of dissemination or transfer to another medium. 3.4 alkali reserve (of a paper): A compound (such as calcium carbonate) that neutralizes acid that might be generated as a result of natural ageing or from at- mospheric pollution, determined as specified in IS0 10716. 1) To be published.

IS0 9706:1994(E) 0 IS0 4 Principle Strictly speaking, the only way to test the perma- nence of a paper is to store it under the relevant conditions for a long time, perhaps for several hun- dred years. In practice, one has to rely upon obser- vations made on historical documents and on present knowledge about factors, expressed in terms of paper properties and paper composition, that promote a high degree of permanence. In this International Standard, the requirements are given in terms of - minimum strength, measured by a tear test; - minimum content of substance (such as calcium carbonate) that neutralize acid action, measured by the alkali reserve; - maximum measured - maximum and minimum pH values of a cold water extract of the paper. content of easily oxidized by the Kappa number; material, 5 Required characteristics 5.1 General A sample of the lot under inspection shall be obtained as described in IS0 186. The paper used for testing shall be free from obvious defects, such as large specks, holes and wrinkles. The presence of an in- tended watermark is not considered a defect. 5.2 Strength properties For papers of grammage 70 g/m* or more, the tearing resistance in any direction (machine and cross) shall be at least 350 mN. For papers of grammage in the range 25 g/m* to 70 g/m 2 , the tearing resistance, ex- pressed in millinewtons, shall be at least r as calcu- lated from the expression: Y = 6g - 70 where g is the grammage of the paper [g/m*], and the constants “6” and “70” are given the dimensions [mN-m*/g] and [mN] respectively. The samples shall be conditioned at 23 “C
