ARAUJO, Juan Facundo. Established requirements for ISO standards for permanent papers. Inf. cult. soc. [online]. 2011, n.24, pp.87-96. ISSN 1851-1740.

Most of the national and international documentary heritage are on paper. From industrialization in the manufacture of such material, paper with acidity levels has been produced which, together with other factors, has been causing the deterioration of this type of documentary heritage. In recent decades, with the incorporation of new paper production processes this problem has been partly solved. The international standards organism ISO has drafted two rules in this connection: ISO 9706 and ISO 11108. With the spread and recommendation for the use of permanent paper for preservation of documentary heritage in the long term, it is essential to know the standards and be well informed. This article describes the variables in the manufacture of paper that influence the permanence of the papers. It also identifies the concepts and history that surround both ISO standards  and the main characteristics and component parts of them. The annex provides a glossary of key technical terms used.

Keywords : Permanent paper; ISO; Acidity; Conservation.
