Paper-Requirements for stability for general graphic applications-Scope amd Principle

Posted Date:2026/2/3 1

1 Scope

This document specifies the requirements for the stability of paper for general graphic applications. It is applicable to all types of uncoated, coated and filled papers.

NOTE For information on International Standards on paper permanence (see ISO 9706), archival paper permanence and durability (see ISO 11108) and on paper stability for general graphic applications (see ISO 20494), refer to Annex C

3 Terms and definitions

3.1 paper stability

ability of paper to retain its intended functionality for general graphic applications (3.2), under normal use and storage conditions

Note 1 to entry: Stability for the purpose of this document differs from permanence which is required for paper used for documents to be stored over long periods of time, as in libraries, archives and other protected environments (see ISO 9706).

3.2 general graphic applications

printing and writing on graphic paper for all applications not intended for permanent storage

Note 1 to entry: Typical products used for general graphic applications include newspapers, magazines, catalogues, books, office printouts and copies.

3.3 alkali reserve

compound (such as calcium carbonate) that neutralizes acid that might be generated as a result of natural ageing or from atmospheric pollutants

Note 1 to entry: Determined as specified in ISO 10716.

4 Principle

In this document, the requirements for the stability of paper for general graphic applications are given in terms of

-- minimum tearing resistance prior to accelerated ageing,

-- retention of tearing resistance after accelerated ageing,

-- minimum content of a substance (such as calcium carbonate) that neutralizes acid action, measured by the alkali reserve test, and

-- maximum and minimum pH values of a cold water extract of the paper.
